I don't have a definitive answer. For one thing, the climate you're in makes a difference. From what I've been told, if the temperature gets low enough outside, the engine may never reach the point where all of the moisture gets burned off.
As a general rule of thumb, I would take a WAG and say probably about 10 miles at highway speeds. If you live where it gets cold in the wintertime, it's probably gotten warm enough about at the point where the water vapor coming out of the exhaust disappears even at an idle. Cars that get thoroughly warmed up frequently with regular trips on the highway last longer than ones that are used for short trips. They have better fuel economy, too. --Geoff On 10/12/06, rebecca risberg <[EMAIL PROTECTED]> wrote: > > how for does a car have to be driven for the oil to be hot enough to burn > off the moisture? i drive my car long enough for the temp gauge to come off > of C. does this matter? > > Geoff <[EMAIL PROTECTED]> wrote: > All cars have a risk of developing sludge inside the engine.
