Maintenance for High Mileage Vehicles in Tucson, AZ

Many people in AZ 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 Tucson 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.

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.
