Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it's no wonder that engine oil needs to be changed frequently! You've probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufactruers have introduced extended oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change. The key phrase here is "under the right conditions". If you look at your owner's manual, you'll see two different maintenance schedules: one for "normal" driving conditions and one for "Severe Service". Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That's why at AutoN ... read more

Working up a sweat is a great thing to do in a gym, but not in your car. When your car's AC System has a problem, you'll often feel it right away. The question is, how long do you put up with it? You know, the old comfort versus cost dilemma. But a more comfortable drive has a lot of benefits, and keeping the AC System well maintained can help prevent expensive repairs. A common cause for AC failure is water and air in the system. The system does not work as well with air in it. And water can cause rust that leads to damage of the A/C components. Also refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system, making it work harder to try to cool the air. That is why periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system so it cools better and lasts longer. You sh ... read more

Modern cars and trucks run on 12 volt electrical systems. 12 volts is enough to get the job done without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks, windows and sun roofs. And then we have all the power outlets for our cell phones, computers, and DVD players. We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off. Fortunately, battery technology has given us resilient batteries that are able to meet these strenuous requiremen ... read more

One of the most popular vehicle modifications in CA is custom wheels and tires. Custom wheels help you stand out from the crowd without spending a lot of money, and custom tires can help you fine tune your performance. Not that long ago, new cars came with just one or two tire and wheel options. Now manufactruers are offering more choices and over a third of new vehicle buyers choose custom wheels. That seems to have fueled public demand for custom wheels in all vehicle categories. The available styles, colors and finishes are endless. You're sure to get the look you want - from sleek and stylish to tough and aggressive. While custom wheels are largely a matter of taste, custom tires are a matter of function. That is not to say that there are not a lot of cool looking tires out there, it's just that tires are vital to your safety, so there are some important practical considerations. Let's look at it in terms of extremes. Think about the enviro ... read more

CA new car dealerships are happy to leave you with the impression that you should have all of your scheduled automotive maintenance performed at the dealership during the warranty period. Some go so far as to imply that your warranty protection depends on it. In fact, nothing is further from the truth. Federal laws in both the United States and Canada specify that you do not have to have your vehicle serviced at a dealership to maintain warranty protection. The laws further state that a vehicle manufactruer cannot mandate that you use their particular brand of replacement parts or fluids. This certainly means you have many more service options, but what about quality? First off, it is important to know that vehicle manufactruers do not make all of their own parts. They look to thousands of independent suppliers to manufactrue the parts that go into your car or truck. Many of these same manufactruers that make the parts that are original equipme ... read more

Sometimes we hear people say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's cars and trucks 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 folks don't realize how high tech automotive fluids have become. Fluids like, 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 prematrue wear and corrosion. Time and miles 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 ... read more

Did you know that today's cars carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969? New cars have as many as 12 networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, computers have been controlling about 85% of your vehicle's functions. Cars have sensors for manifold air temperatrue, coolant temperatrue, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem? It's simple - the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores ... read more

The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure. A few auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection syst ... read more

Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel's off center, you have uneven tire wear or your car doesn't feel like it handles right. When all of a vehicle's wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin. Driving for an extended time when you're out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You'll have to replace your tires sooner, but even worse - you may cause prematrue wear to your suspension system, which can be really expensive. The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ways. The first adjus ... read more

If you're reading this article, then you are probably a CA driver that cares about your car and how it runs. Even though you care, there is still that moment of dread when your service technician tells you the manufactruer recommends some additional service. Your heart beats a little faster, your blood pressure rises. You worry about spending more money than you expected. And you worry that if you say "no" you might be harming your car or compromising safety. At the risk of sounding like your dad, you really should have done your homework. All of this stuff is in your owner's manual. But it is not like you want to keep your maintenance schedule on your nightstand for bedtime reading. Cars are complicated machines and it takes care to keep them running well. That is why manufactruers have maintenance schedules that explain how to keep your vehicle performing efficiently and prevent costly break downs. In ... read more
