Everyone in , knows we are advised to go to our dentist twice a year. Oral-conscious residents have a teeth-cleaning and examination. Once a year, we get x-rays to look for problems that can't be seen with the naked eye. When our dentist is done, he/she tells us what was found - "Everything's fine, see you in six months." Or "You've got a small cavity starting, let's schedule an appointment to take care of it." By the time you leave, you have a plan for addressing any necessary issues.
This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.
If folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our car maintenance?

Following the car maker's recommended intervals can be confusing. First, there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing …you get the point.
Every item has a recommended interval and it's hard to keep it all straight - even if you're part of the 1% of the auto owners that read their owners' manual.
And if you have more than one , the complexity is multiplied. You'd need a computer to keep track of everything. Well, that's how your service center does it. For example, subscribes to automotive databases that have your vehicle's recommended intervals. You may have wondered how they know what else to recommend when you take your car in for an oil change - it's all in the database.
Well, it's not all in the computer. There are other variables that can't be accounted for in the schedule. Things like weather conditions, altitude, and where and how you drive in . Talk about these things with your technician and you may decide that the severe service schedule in your owner's manual is more appropriate.
Since anything that's not expressway driving in moderate weather is considered severe, most of us do at least some of that around , and it should be taken into account.
Let's take your basic oil change as an example - what issues are involved? The oil you put in your car is a blend of base oil and special additives. There are detergents to clean the inside of your engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.
Now, these additives deplete with use and time. That's why most maintenance recommendations include both a time and mileage element - like 3 months or 3,000 miles, whichever comes first.
It's easy to think, "Gee, I've only driven 2,000 miles in the last 3 months. I can wait on that oil change." But you need to remember that the inside of your engine is a harsh environment. The oil is contaminated with combustion by-products that starts degrading its effectiveness even when it's just sitting there.
A lot of people in don't realize how harmful it is to skip an oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it's clogged up because you haven't changed it, it can't trap any more.
Oil sludge is another problem. Sludge is oil that has turned to a gunky jelly - think ‘Vaseline'. Obviously, sludge doesn't lubricate. It can also clog small oil passages so that all the parts don't get properly protected by the oil. That'll lead to premature wear.
If you've missed some oil changes, don't despair. Just talk with your service advisor at . Fess up - you'll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your car on the road and avoiding costly repairs.
