How often do you change your oil? Maybe too often:

“There was a time when the 3,000 miles was a good guideline,” said Philip Reed, senior consumer advice editor for the car site Edmunds.com. “But it’s no longer true for any car bought in the last seven or eight years.”

Oil chemistry and engine technology have improved to the point that most cars can go several thousand more miles before changing the oil, Mr. Reed said. A better average, he said, would be 7,500 between oil changes, and sometimes up to 10,000 miles or more.

You know, I’ve never changed my oil every 3,000 miles. Every car I’ve owned, going back to about 1980, I’ve changed the oil every seven or eight thousand miles and I’ve never had any problems. No unusual engine wear, no weird noises, no parts wearing out, no nothing. My current car (ten years old) almost seems to not even use any oil. I can drive it five or six thousand miles and it’s not even down a quart. More like a pint. Or less.

At this point, I have a feeling I might not ever get an oil change again in my life if it weren’t for the fact that it happens automatically when I take the car in for routine service every year or two. So far, no problems after a decade. Will I regret this slothful attitude someday?

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
