Change is Good (Oil Change)

You’ve heard that expression, change is good. When it comes to your vehicle’s oil, change is not only good, it’s vital for the health of the engine. But there’s one question that puzzles many drivers: how frequently should my vehicle’s oil be changed? There is not one simple answer, but here are some guidelines that will help.

It used to be pretty much a rule of thumb that vehicles got their oil changed once every 3 months or 3,000 miles/5,000 kilometers. But times have changed. Oil formulations have gotten better and engine designs have made longer oil change intervals possible.

Most experts advise you to read the recommendations that come from the manufacturer that designed and built your vehicle. Their designers and engineers know more about your vehicle than anyone else. They spell out their recommended oil change interval and type of oil in your owner’s manual. Many automakers say you can go at least 5,000 miles/8,000 kilometers between oil changes and many recommend even longer intervals now. If you use synthetic oil, it doesn’t have to be changed as often.

Ever wonder why you have to change your oil? Your vehicle lives in a dirty environment. Contaminants build up in your engine oil and, after time, they inhibit the lubricating properties of the oil. Without optimal lubrication, increased friction inside the engine starts wearing down the metal parts, shortening the engine’s life.

Oh, and driving habits matter, too. Short trips with a lot of stop-and-go driving will stress your engine and oil more than longer trips at highway speeds.

The bottom line is this: Oil changes are good for your vehicle in so many ways and probably the most important maintenance service you can get.
