• Introduction to Diesels for Ann Arbor, Michigan

    2018-02-20 12:02:03



    Something you're going to be hearing a lot about around Ann Arbor, Michigan, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.

    Most people in Michigan are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in Ann Arbor, Michigan. But that's about to change.

    In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Ann Arbor, Michigan, so we are now ready to start seeing more diesel options offered over the next few years.

    Why are so many Ann Arbor drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved fuel economy.

    Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Ann Arbor with diesel engines?

    If you think back to the late 1970's and early 1980's, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in Michigan have evolved considerably.

    They are quiet, clean – and powerful. They're so refined that many Ann Arbor drivers can't even tell they're riding in a diesel powered vehicle. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

    Another thing the Ann Arbor green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Ann Arbor restaurants. There is a lot of buzz about hybrid cars in Michigan. Look to diesel-electric hybrids in years to come to make a good idea even better.

    Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import brands have plans to bring more of their outstanding diesel engines to Michigan as well.

    New Ann Arbor diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it's important to keep your fuel system clean with a diesel.

    The good news is that Convenience Auto Service in Ann Arbor is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

    When we tell you to look for more diesels on Ann Arbor streets, you won't be looking for smoky tail pipes as a clue. You also won't be listening for that familiar big rig rattle. And, you certainly won't be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

  • Automotive Tips from Convenience Auto Service: A Broken or Damaged Timing Belt

    2018-02-11 09:35:03

    The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around Ann Arbor.

    An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.

    It is important for Ann Arbor drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at Convenience Auto Service in Ann Arbor if it’s time for your timing belt to be replaced.

  • Beware of Cheap Tires in Ann Arbor

    2018-02-06 01:14:03

    Do you like to shop for shoes in Ann Arbor?
    When buying a running shoe, is quality important?
    Does durability matter as long as the shoes look fabulous?
    Would you rather have one pair of long lasting shoes or two pairs of lower quality shoes at the same price?

    Is the warranty important when buying tires?

    Ann Arbor drivers should also think about the safety aspect of tires. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. You want to be sure they hold the road and provide good traction on Michigan freeways and surface streets. If you carry heavy loads or tow a trailer on Michigan highways, the tires need a high load rating.

    Ask your friendly and knowledgeable Ann Arbor tire professional at Convenience Auto Service. I think it's important that Ann Arbor residents understand the effect of price on a tire's quality, performance and durability. When I was a kid, my dad would say, “Pay twice as much and buy half as many.”

    The same principle applies to tires. The major tire brands that you're familiar with in Ann Arbor are known as Tier 1 tires. These tires are high quality and well-engineered. Comparable vehicle Tier 1 tires are usually priced similarly.

    Stepping down, you come to private label tires. Some large Michigan tire store chains carry tires with their own brand. It's important to know that most private label tires are built by the same Tier 1 companies that you are familiar with – so you are pretty safe in choosing them. To be sure, you can ask your Convenience Auto Service tire professional which manufacturer makes their private brand.

    The lowest priced tires on the market in Ann Arbor are Tier 3 tires which are usually imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.


    What's the difference in the tires with high mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

    Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built. Buy value – not price.

    Give us a call.

  • Hey Ann Arbor Drivers: How Do You Save Gas?

    2018-01-28 10:23:03

    Higher Ann Arbor fuel prices aren't going away any time soon. That's not good news for our wallets. A lot of Ann Arbor drivers are trying to find ways to cut down on fuel consumption and hang on to some of their hard-earned money.

    North Americans drive billions of miles less during months of high fuel prices. That's right, billions. Of course Michigan vehicle owners can't stop driving altogether, so we still need to find other ways to cut fuel bills.

    Preventive maintenance at Convenience Auto Service in Ann Arbor and good vehicle care can actually pay for themselves by lowering our fuel consumption. Here's a real-life example of how that can work.

    A family planned a four-day camping trip. Before leaving, they took their SUV into Convenience Auto Service for an oil change. They flushed the cooling system, serviced all three differentials and cleaned the fuel system. They replaced the PCV valve and breather element. Then they checked the tires to ensure they had enough air.

    This was several hundred dollars in maintenance and repair. You may be thinking how the family could possibly recoup the cost in gas and save money. First of all, the repairs all needed to be done anyway. Even if the costs aren't recouped, many of them will pay for themselves by preventing even more costly repairs later. Also, the family had planned and budgeted for the routine maintenance, so it didn't cut into their trip allowance.

    The SUV pulled a one-ton trailer and hauled everything the family needed on their camping trip. At the end of the trip, the owner was surprised to learn the SUV had actually gotten better gas mileage than it ever had before—even with that heavy load. The repairs and maintenance at Convenience Auto Service had improved the gas mileage by 25%! The family saved $48.00 in gas on their four-day trip. And they are continuing to reap rewards from the improved mileage.

    So what can you do to save fuel? First, stay caught up on routine maintenance at Convenience Auto Service. Almost every maintenance item listed in your owner's manual will maintain or improve your fuel economy. Second, take your vehicle into Convenience Auto Service for scheduled tune-ups. And third, take care of needed repairs. You may be surprised at how much you save at the pump and probably with the improved vehicle performance as well.

    If your Check Engine light is on, find out why and take care of it. Some of the problems that set off that warning light can seriously reduce fuel efficiency.

    As you schedule preventive maintenance, don't forget your tires. Proper tire pressure and wheel alignment are both essential to good fuel economy.

    Here's some more auto advice about some simple things you can do to improve fuel economy, beyond maintenance and repairs:

    Dump the junk. More weight in your car equals more fuel. You'd be surprised how much stuff people carry around in their cars. That adds up to a lot of extra fuel. One hundred pounds of extra stuff in your vehicle can add up to the loss of one mile per gallon of fuel.

    Get the lead out. No, don't speed up, slow down. Get the lead out of your right foot. The single biggest drain for most Ann Arbor vehicles is speeding or sudden accelerations. Slow down and go easy on turns and lane changes, and don't treat every stoplight and stop sign like a green flag. These small changes can add up to quite a bit of change in your pockets.

    We haven't mentioned the pills you can drop in your gas tank or special devices you can hook on your fuel line in order to increase fuel efficiency. There's a simple reason for that: they don't exist. There may be some truth behind some of these claims, but most of them are full-out scams. And if any of these things do actually help, it's not nearly as much as the things we've listed here.

    Be smart. Your vehicle and your wallet will thank you for it.

  • Fuel Injector Cleaning at Convenience Auto Service

    2018-01-22 03:41:03

    In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected vehicle driving down Ann Arbor roads.

    Most fuel injectors for gas engines are known in the Ann Arbor automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

    A few have recently introduced gas direct injection systems on some engines. They are now available at some Michigan dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

    Although more complicated, direct injection technology promises greater power with improved fuel economy. Michigan motorists can expect to see more of it in the future.

    High temperatures under your vehicle hood and variations in Ann Arbor gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

    When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor fuel economy and loss of power. So it's wise for Ann Arbor residents to keep their fuel injectors clean.

    Your technician at Convenience Auto Service can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

    Proper maintenance of your vehicle fuel system means that you will spend less on gas, enjoy strong performance and prevent repair bills down the road.

  • Good Service at Convenience Auto Service Equals Good Fuel Economy in Ann Arbor

    2018-01-14 08:24:03

    Whether we're trying to save money, save gas or save the environment, most of us Ann Arbor drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in Michigan, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?

    The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.

    Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fuel doesn't burn efficiently. Replacing that faulty sensor can save you 40% at the pump. That's certainly a reason to improve your car care and have the automotive professionals at Convenience Auto Service inspect things once in a while.

    A faulty oxygen sensor will activate the check engine light. So will a lot of other problems that are big fuel wasters. Finding out why your light is on and fixing the problem will also improve your fuel economy. Bring your car into Convenience Auto Service in Ann Arbor and we will take care of it for you.

    What about tires? Ann Arbor drivers have all heard that keeping them inflated will improve our gas mileage. True? Yep. It's a 3% savings for that one. And even small drops in tire pressure can start to add up, so a weekly tire check is in order.

    Using the correct weight in motor oil is another way you can save at Ann Arbor area gas pumps. It adds up to a 2% savings.

    What about that courteous driving? That doesn't cost us anything and doesn't require our Ann Arbor service center to implement anything. Is it worth the bother?

    Again, the answer is yes. Sudden acceleration, such as charging away from stoplights, sudden stops and quick lane changes all add up in lowered fuel economy. Taking it easy when you drive on Michigan roads amounts to a 5% savings around town and a whopping 33% savings on the freeway. Is it worth your time to slow down? How much do you get paid?

    Speeding is another way we ding ourselves at the gas pump. We've all heard that it's okay to drive five miles over the speed limit, but that actually hurts our wallets. Eventually it could add up to more than a speeding ticket. An extra five miles over the speed limit ends up costing us 7% per gallon. Fifteen miles over? 23% Now there's a reason to slow down.

    Another thing Ann Arbor vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping one hundred pounds of extra weight adds up to a 2% savings at the pump.

    So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

    All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in Michigan.

  • Cooling System Components

    2018-01-08 12:06:04

    Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Ann Arbor auto owners don't give much thought to until it fails and then they're stranded by the side of a road in Michigan.

    Cooling systems fail more often than any other mechanical system – usually because of neglect. Don't you hate it when something breaks and you could have done something to prevent it?

    The good news is that if Ann Arbor drivers take care of their cooling systems, they can keep working for the life of their car.

    Here at Convenience Auto Service in Ann Arbor, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

    It sounds complicated, but we Ann Arbor residents don't have to be experts – we can leave that to our friendly and knowledgeable service advisor at Convenience Auto Service. But, having an overview will help us remember how to take care of your car's cooling system.

    Most Ann Arbor folks would be surprised to know that burning fuel in your engine produces up to 4,500 degrees F/2,500 degrees C of heat. And all that heat has to be dealt with. If the heat can't be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.

    Now the water pump is what forces the coolant through passages in the vehicle engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some cash on replacing the belts and water pump is much less than the cost of repairing the extremely massive damage that can be done when an engine seizes.

    There's another little known but important part of the coolant system that protects the engine. It's called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.

    It is hard to believe, but the expanding frozen coolant is enough to actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.

    The team at Convenience Auto Service can check your cooling system and make any necessary adjustments or repairs. Give us a call.

  • Ask Convenience Auto Service About the Importance of Service Intervals

    2018-01-03 02:05:03

    Today in our Convenience Auto Service blog, we're going to talk about following recommended service intervals. Your vehicle isn't the only aspect of your life with recommended intervals: What about six-month dental cleanings and regular physical exams? Then there's laundry, mowing the lawn, paying your electric bill, changing your furnace filter - you get the idea.

    Now, what would happen if you didn't follow these intervals? For one thing, your teeth may get more cavities. You might not discover health issues that benefit from early detection and treatment. And you'd have to wear dirty clothes, be embarrassed by your overgrown lawn and have your power shut off.

    We all realize there are some things in life that we have to take care of regularly. If we don't, there are negative consequences. Our quality of life diminishes and it inevitably costs more money.

    Have you ever wondered, "How often should I bring my car in for scheduled maintenance?" You can let your friendly and knowledgeable Convenience Auto Service technician remind you of the manufacturer's recommendations. He has checklists of what the manufacturer recommends and can find potential problems when he inspects your vehicle. Rely on Convenience Auto Service professionals to help you make good car care decisions, that's our job.

    For those in Ann Arbor who want to be more proactive with their vehicle care, here are some simple ways to remember what has a maintenance interval:

    First: fluids. If it's liquid, it's got a replacement schedule. Oil, transmission fluid, coolant, power steering fluid, brake fluid, differential fluid, etc.
    Then think tires. They need air, rotation, balancing, and alignment. And while you're thinking tires, think brakes and shocks.
    And what makes your car go? Air and fuel. Air filter replacement, fuel filters and fuel system cleaning.

    Of course there are more items, but if you remember to take your vehicle into Convenience Auto Service for these things, your friendly and knowledgeable service advisor will help you with the rest.

  • The Maintenance Free Myth

    2017-12-11 03:15:03

    Sometimes we hear people in Ann Arbor say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most Ann Arbor drivers don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.

    Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard to emphasize and show how important it is to get things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and money. But they are tales of a stitch in time saves nine.

    The first comes from someone who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on a highway in Michigan and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been completely replaced - just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundreds of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

    Another story involves the true cost of skipping an annual inspection. This guy took his SUV in for the Michigan safety inspection to renew his registration. At the Ann Arbor inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the money. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind - over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a little on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story for Ann Arbor drivers: don't skip your annual inspections. The irony is that many Ann Arbor service centers would have done a brake inspection for free.

    Next: a teenage daughter and a curb. Daddy's little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn't get an alignment. The impact was hard enough to ruin the tire - so it was enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later - and then an alignment.

    Situation: son and wife with cars from the same vehicle manufacturer with essentially the same engine. Our staffer checked the son's maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done - it cost several hundred dollars. His wife's car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed, the entire head was shredded and it had to be replaced. The cost: several thousand dollars. Does he wish he had checked the vehicle manufacturer’s maintenance schedule? You bet he does - every time he passes a big-screen TV.

    The team at Convenience Auto Service in Ann Arbor recommends taking care of little things before they become big things. And when you take care of the little things, you can make your car run better.  Plus, it is more economical to operate in Michigan. Remember to save those maintenance records. It'll show potential buyers that you've taken care of your vehicle and it will help you get a better price. Or when you buy a used car, check those records. If there aren't any, assume that the maintenance hasn't been done and take it to Convenience Auto Service in Ann Arbor for an inspection. Take care of unperformed routine maintenance sooner rather than later.

  • Keep Your Tires Well Rounded in Ann Arbor: Tire Rotation and Wheel Balancing at Convenience Auto Service

    2017-12-06 07:11:03

    Taking care of our tires is part of vehicle care for Ann Arbor drivers. We know they have to be replaced when they wear out, but tires also require some preventive maintenance. This maintenance will improve and extend the life of the tires, so it's well worth the effort and expense for Ann Arbor drivers to get it done. Tire maintenance includes keeping tires properly inflated, rotating tires and balancing wheels.

    The recommended tire pressure for a vehicle's tires is printed on a sticker on the inside of the driver's side doorjamb. A lot of engineering goes into calculating the correct pressure, so it's an important number for Ann Arbor vehicle owners to know. Not following this recommendation can throw off the suspension system and can lead to tire damage. Underinflated tires wear out more quickly than properly inflated tires. Vehicles also get better traction and handling on properly inflated tires. Check your tire pressure at least once a week and add air if necessary.

    Don't be tempted to add a bit of extra air to your tires when you fill them. Overinflated tires will cause the center tread to wear unevenly because of improper contact with the road. It will also affect the handling performance of your vehicle.

    Rotating tires allows all four tires on a vehicle to wear evenly. Front tires get more wear than rear tires because they do most of the work on turns. Tire rotation allows all of the tires to spend time on the front of the car so they all experience the extra wear.

    For most vehicles, tire rotation is simply a matter of moving the front tires to the rear and vice versa. Some vehicles, however, recommend a cross-rotational pattern. Other vehicles use asymmetrical tires, which means the right tires have to stay on the right side of the vehicle and the left tires on the left. Some vehicles use differently sized wheels on the front and back of the car and should not have their tires rotated.

    What kind of rotation do you need? Check your owner's manual or talk to your service advisor at Convenience Auto Service. Your owner's manual will have information about how to rotate your vehicle's tires as well as letting you know how often you should get it done. For most vehicles, that's usually every 5,000 miles or 8,000 kilometers Your friendly and knowledgeable Convenience Auto Service professionals can also offer auto advice about tire rotation. A quick tire inspection can also indicate whether or not your tires are due to be rotated.

    When it comes to tire maintenance for Ann Arbor drivers, wheel balancing is usually what we know least about. Balancing a wheel is necessary to keep it in constant contact with the road. If a tire is not balanced properly, it actually hops along the roadway. You can feel this hopping as a vibration in your steering wheel if the unbalanced tire is a front tire. You'll feel the vibration through your seat if a rear tire is unbalance. Properly balancing your tires is important and will extend their life span, improve handling and improve the safety of your vehicle. When you replace your tires, the new tires need to be balanced.

    Never use different sized tires on the same axle of a vehicle. In other words, your front tires need to be the same size and your rear tires need to be the same size. Mixing sizes can lead to some serious handling problems for Ann Arbor drivers.

    If you have an all-wheel drive or four-wheel drive vehicle, all four tires need to be the same size. If your tires are wearing out, you can sometimes make a new tire purchase fit within your budget by only buying two tires at a time. When you do this, the new tires should be installed on the rear of the vehicle. Rear tires are more in need of the traction than your front tires to avoid spinning out on slippery surfaces. If you drive a vehicle around Ann Arbor, you need tires, so you need to know how to care for them. The safety of your vehicle can depend on the condition of your tires.
