1. Don’t Drive
Want your car to last? Don’t use it. That sounds obvious, but it’s worth keeping in mind.
Chances are there are plenty of times when you currently use your car that you could be walking, biking, using public transportation or carpooling — choices that are better for the environment, your wallet, your health, and the car you won’t be driving. It’s simple: The less you drive, the longer your car will last.
2. Make Fewer Short Trips
Short trips of less than 10 minutes can be particularly hard on a car, resulting in excessive wear and tear. During a short trip, your car’s engine never has a chance to reach its full operating temperature.
So what? Here’s why it matters: One of the byproducts of engine combustion is water. When an engine reaches its operating temperature that water turns to vapor and is expunged, either out the tailpipe or the crankcase ventilation system. On a short trip, however, that water stays inside your car’s engine and exhaust. Unfortunately, water is one of only three ingredients necessary to make rust (you’ve already got the other two, oxygen and metal), and rust kills. Look at any of my brother’s cars.
A further complication of condensation and water is that it dilutes your oil, which then does a poorer job of lubricating the engine. If you can’t avoid taking lots of short trips, we recommend you change your oil frequently, such as every 2,000-3,000 miles.
