Many people in Illinois are keeping their vehicles longer. The economy has influenced that, but the fact that modern vehicles are more durable and reliable means that owning a high mileage vehicle doesn't have to be a painful experience.

Local car owners in Plainfield with over 100,000 miles on their vehicles often ask which service intervals they should follow. Let's start with the special needs of the older vehicle...

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There'll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they're worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Talk with your Plainfield service advisor at Tuffy Tire & Auto Service Plainfield about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your vehicle is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Plainfield auto service advisor at Tuffy Tire & Auto Service Plainfield help you with an assessment of your older car or truck. If you haven't gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it's time to start taking care of those things. It'll help keep you on the road for many more happy miles.
