I drive my 2006 Ford Escape a couple of times a week, maybe 10 miles per day, with occasional longer trips. The average is less than 3000 miles per year. The owner's manual specifies oil changes at every 5000 miles or 6 months, whichever is earlier. In my case, with the low miles driven, do I still need to change oil every 6 months, or can I extend the interval by a couple more months?

Ide go with what the owners manual recommends. An oil change is cheap insurance.

As a disclaimer, its hard to argue with the manufacturers recommendation, they built the car, we didn't.


That said, reviewing a ton of oil analysis on the Bob site, it seems pretty reasonable to extend that almost up to a year, as long as you really do take the occasional longer trip. If you never get the oil at temp for a while, it will break down quicker. Personally, in your scenario, I would feel pretty good going another few months. While in most cases I would feel good going to a year, or even longer, I'm not as comfortable I would in your case.


The only low mileage good condition car oil analysis I've seen that looked bad after a year was one that was short trips only.

If you intend to keep the car a while, just change it every 6 months. If you're not planning to keep it more than a year or two, I would change it yearly.

The reason why you want to avoid letting old oil sit in the engine for longer than recommended is that the oil tends to accumulate carbon contaminates from combustion, as well as fuel residues and moisture from the crankcase that tend to form acids in the oil. This acid can have a detrimental effect on bearings and bushings over time. Short drives (like what you do) can accelerate this effect as they don't allow the oil to get hot enough to drive off some of the contaminates.

My recommendation is to do what the manufacturer recommends.

That site has frequently questionable information, usually from a fringe group of people that like seeing what their car can do/take. And not just on oil. It's like a big experiment. Just a quick interjection.

I would err on the side of being conservative. Change the oil at least as frequently as the owner’s manual says. Even if you don’t plan to keep the car forever, you might have to keep it longer than expected.

The cheapskate advice that reeks of “Screw the next owner” is one reason why I stopped buying used vehicles a long time ago.
