Deep Clean Your Fuel System At

Having trouble with your fuel system? Bring your into for a check up.

,


Today we're talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they've had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That's the fuel filter's job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner's manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It's real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can't do that if they're dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it's burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it's dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it's dirty as well.

Do all these things and your engine's air and fuel will be as clean as possible. You'll get much better fuel economy and better power

Fuel System Cleaning At

Is your car sometimes hard to start on an early morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

,

Most of our in have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some people are interested in buying fuel system cleaners that you can pour into your gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see your service center at . has the professional tools and chemicals to really do a complete service.

Your service center at in uses a process that gives your car a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you'll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts.

Fuel system cleaning is just one of those recommended service items that helps keep your vehicle running strong. As with all maintenance, it can help avoid costly repairs that often result from not taking the right preventive steps. And you will notice the difference in how well your car runs. Check with your service advisor at in to see when your car is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure.

Smooth Shifting in : Transmission Service

So you have some exciting plans for the weekend. You’re going to take some of your , friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. But you want to make sure that your maintenance is up to date.

Think about it – heavy traffic on the way out of . There’s hilly terrain as you get to the lake. Some dirt roads – and its going to be pretty hot in this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.

Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the local lake for you is really severe duty for your transmission.

It’s important to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced at on schedule to make sure it runs efficiently.

An automatic transmission contains a maze of passages through which the fluid has to pass to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems.

Neglect your transmission for too long, and it can fail. You really don’t want to pay for a major transmission repair.

This reminds us of how much of our driving around , is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold weather. Dusty roads and city driving around , add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.

While you have your vehicle in, ask for a trip inspection. Your , service technician at will check your belts and hoses and let you know if your brakes are in good shape.

Now, don’t forget the sunscreen.

Automobile Fluids For Your

If you've walked through the automotive fluids of an auto parts store in , you'll know how overwhelming the sheer number of products available can be. How do you know what's right for your vehicle?

As you know, these fluids all serve a function in making your car run as you drive around the area. Your vehicle manufacturer has specified a particular type of fluid for every system from the motor, to the cooling system, brake fluid and so on. When you realize that not every variation is applicable to your vehicle, the task becomes more manageable.

First let's talk about why there are so many varieties. Starting with motor oil, we see that manufacturers match the properties of a particular weight or type of oil with the design needs of the engine. For example, engines with sophisticated valve trains often require a thinner weight of oil.

Some vehicles around come from the factory filled with synthetic oil and the recommendation to use it for life. The safe bet is to always use what the factory recommends. The recommendation is what's been proven to work in function and durability tests. The recommended oil is also a factor in determining oil change interval schedules.

A good quality oil has more additives that are engineered to clean and protect the engine. They cost a bit more, but are worth the extra protection. If you buy budget oil, you might want to consider shortening your oil change interval.

Sometimes fluids are developed specifically to meet the needs of a particular family of engines. An example would be coolant. Because of the different materials used to build the cooling system, the coolant has to be formulated to protect those parts, which vary from manufacturer to manufacturer, from corrosion. We've seen special coolant in for General Motors, Volkswagen, Chrysler and others.

The same is true of transmission fluid and brake fluid in recent years.

The really good news is that your service center has databases that tell them the recommended fluids for your vehicle. This takes all the guess work out. If you have some special needs, like a higher mileage engine or want enhanced performance, ask your service advisor for upgrades or additives that'll meet your needs while being consistent with the manufacturer's recommendations.

Of course, your full-service oil change will top off your fluids. But it's a good idea to have some of everything at home in case you need to top something off yourself or to take on a trip. Ask your service advisor at or check your owner's manual for fluid specifications.

It's important to know that there are national warranty laws that say that a manufacturer cannot require you to use their brand of fluid to maintain your warranty. That said, there are two things that may affect your warranty.

Using the wrong type of fluid may void the warranty. Going back to radiator coolant, the correct type protects against corrosion and the wrong type will not. So it's important to be right.

Also some warranty protections are conditioned on taking care of scheduled preventive maintenance. Please review your warranty if you have questions.

Fuel Saving Tip: Tune Up

Have you ever gone to to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That's why they tune up together.

Now this is no surprise; I'm going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.

We call this, (ta-da) a tune-up. When an orchestra's out of tune you get a bad concert. When your vehicle's out of tune you get bad performance and bad fuel economy.

So check your owner's manual for recommended tune-up intervals. Or ask your service advisor at what he thinks.

...Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Defensive Driving In

There was a man in who learned that most car accidents occur within a mile of home – so he moved. (Just Kidding!)

When we think of defensive driving, we often focus on our local highway situations. The fact of the matter is we need to be just as careful close to home in , because that's where we do most of our driving. We can't let our familiar surroundings keep us from driving defensively.

Defensive driving begins with the proper attitude. Have in mind that you won't let anyone take your safety away from you. You'll be aware of your surroundings, road conditions, other vehicles and hazards. And the first person to be concerned with is you: start with your own environment.

Don't leave without securing all occupants including children and pets. Watch for loose items that can become projectiles during evasive maneuvers.

Driving too fast or too slow increases the chance of an accident.

Never drive impaired: Alcohol is a factor in half of all fatal crashes. Never drink and drive.

Other impairments include being sleepy, angry, daydreaming or talking. If you suddenly wonder how you got where you are – you're not paying enough attention.

Keep your windows clean and uncluttered. No fuzzy dice and stickers.

Keep your car in good shape so that it handles properly: Maintain tires, lights, brakes, suspension, wheel alignment and steering.

Always use your turn signals while driving around . Avoid other vehicles' blind spots.

Don't drive faster than your headlights – if you can't stop within the distance you can see, you're going too fast.

Avoid driving over debris in the road. Even harmless looking items can cause damage or an accident.

Keep your wheels straight when waiting to turn at an intersection. That way if you're hit from behind, your car won't be pushed into on-coming traffic.

My daddy always said that when you drive, you're actually driving five cars: yours, the one in front, the one behind and the ones on either side. You can't trust that other drivers will do the right thing, so you've got to be aware of what they're doing at all times.

If you see another car driving erratically, weaving, crossing lanes, etc., stay back. Take the next right turn if you're downtown , or take the next exit on the highway. Notify the police if you see someone driving dangerously in our community.

Never follow too close. The minimum distance is the two second rule. Pick a landmark ahead, like a tree or road marker. When the car in front of you passes it, start counting: 'one-one-thousand, two-one-thousand'. If you pass the landmark before reaching two-one-thousand, you're following too close.

Remember that the two second rule is the minimum – it assumes you're alert and aware. Three seconds is safer. Move out to five seconds or more if it's foggy or rainy.

Someone will inevitably move into your forward safety zone – just drop back and keep a safe distance.

If someone follows you too closely, just move over.

Don't play chicken by contesting your right of way or race to beat someone to a merge. Whoever loses that contest has the potential to lose big and you don't want any part of that. So stay alert, constantly scan around your car and arrive safely.

Is Your Driving Severe?

People near often ask how often they should have a particular service done. It's a great thing to ask. You can look at your owner's manual, or have your service advisor at look up your vehicle in a service database. What you find is often a surprise to people – there are actually two service schedules.

One is the regular schedule and the other is the severe service schedule. Service intervals are shorter on the severe service schedule. When asked, most folks in will say that their driving is normal and that the 'regular' schedule probably applies to them. 'Severe service' sounds pretty extreme – 'I don't drive like that'.

Well, here is what the manufacturers say constitutes severe driving conditions; you can draw your own conclusions.

• Most of your trips are less than four miles.
• Most of your trips are less than ten miles and outside temperatures are below freezing.
• The engine is at low speed most of the time – not on the highway. You operate your vehicle in dusty areas.
• You regularly tow a trailer or carry heavy loads.
• Drive with a car-top carrier.
• Stop and go driving.
• Driving in very hot or very cold weather.

If that's severe driving, what constitutes regular driving? Well, it would look something like this: I live somewhere with moderate temperatures all year round – I'm thinking San Diego here. And I live close to a freeway on-ramp. Everywhere I need to go is right off the freeway, at least four miles from my home. I can drive at a steady 60 miles per hour when I'm on the freeway.

I don't know about you, but that doesn't sound like my normal driving. It sounds more like ideal conditions. I live where it gets hot in the summer and cold in the winter. I run short errands around . Occasionally we load up for family trips.

For me, normal driving includes elements of severe service driving. So here's what I tell people: think about how you drive, where you live, where you go and what you are expecting to with your vehicle in the near future.

Picture a line with 'regular' on one end and 'severe' on the other, and make a judgment on where you fall. If your regular oil change recommendation is 5,000 miles and the severe service recommendation is 3,000 – when should you change your oil? For me, it's closer to 3,000 miles. For my wife, it's closer to 5,000 miles. Your auto service advisor at will be happy to have this discussion with you and help you sort it out.

Just a quick word on why severe service intervals are shorter. One has to do with heat. That can either be external heat from the weather or engine and transmission heat from stop and go driving or working extra hard moving heavy loads or towing. The heat causes the fluids like oil and transmission fluid to break down more quickly and then they aren't as effective.

Another factor is water. Moisture naturally collects in fluids as they cool. In your motor oil, for example, if you don't drive long enough for the oil to fully heat up, the water won't evaporate. Water in the oil can lead to the buildup of damaging sludge.

If you live where the air is dusty or polluted, fluids will become contaminated and filters will get dirtier more quickly.

So make an honest evaluation of your driving conditions. You've made the commitment to take care of your vehicles, so it only makes sense to follow the right schedule.

Nighttime Visibility In

There are a number of factors that contribute to the high nighttime accident rate in the greater area, things like drowsy driving and a higher rate of impaired driving. Without a doubt, visibility is a major contributor. Let's focus on visibility…

It's said that 90 percent of our driving decisions are based on what we see. Nighttime driving has the effect of reducing 20/20 vision to the equivalent of 20/50 vision. What you could clearly see at 50 feet in daylight can't be seen until you are just 20 feet away at night.

Too make sure your headlights are giving you the greatest visibility, visit us at . you'll find us located on , , . Please give us a call to make an appointment: .

Accident avoidance is dependent on reaction time. Reaction time deteriorates measurably in low light conditions. One thing we can do to improve visibility is to make sure our headlights are as bright as they can possibly be.

Headlamps dim over time. They dim so gradually that you may not notice it. Many experts suggest replacing your standard or halogen headlamps once a year.

If your vehicle has standard headlamps, consider upgrading to halogen lamps. They make a big difference. And there are upgrades available within the halogen category as well. This once-a-year expense is very modest compared to the safety benefits.

Some s come with high intensity discharge – or HID – headlamps. These lamps should last for the life of your car. They are very bright and are clearly the best option for nighttime driving. Depending on your vehicle, you may be able to upgrade to HID headlamps. Talk with your service advisor at about options for your car.

Another startling fact is that 90 percent of s on the road have dirty or yellowed headlight covers. Dirty is easy to fix. Just run the window washer over the headlight cover when you stop for gas. Get those bugs and dirt off the cover.

Now plastic headlight covers can yellow or become hazy over time. They can be restored to clarity with a special polishing process. can help you with this service.

It's also vital to keep your windshield clean and streak free when driving at night. Make sure you have plenty of washer fluid and that your windshield wipers are in good working order.

We recommend replacing wiper blades twice a year – in the spring and fall. Fall is also a good time to replace headlamps so you'll be ready for those long winter nights.

What Is A Differential And Do You Have One?

With front-wheel drive being so common these days in , , the differential is just taken care of during a transmission service, so most folks in , don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of mind for our customers. So it's not uncommon for people to not know they have a differential let alone know that it needs service.

Call at for information about differential service, or stop by our , auto center at .

To better understand what a differential does, think about our local high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars in the , area weigh between three and six thousand pounds – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool.

The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that breakdown over time. So manufacturers recommend intervals for replacing your differential fluid.

Your , technician at will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. Then he'll replace the fluid and install the additives if necessary.

Your service advisor can look up the manufacturer's recommended service interval or you can check your owner's manual. Give us a call at for more information about your differential service.

Direct Fuel Injection Update From

For those of you in who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it's atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can't do its job as well. That means less power and worse fuel economy for your and can lead to damaged fuel injectors.

Replacing fuel injectors isn't cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we're talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they'll last a long, long time.
