It's a slow process. Just switch to synthetic. If you know that the motor is really dirty change the filter often, maybe every thousand miles or so, a few times. May take tens of thousands of miles to really clean everything out. No, I've never torn down an engine to verify that it's clean. But enough knowledgable people (e.g. Marshall) have made the cleaning claim about Mobil 1 that I have no reason to doubt it. > In a past life I knew a fellow who would pour the same gallon of > diesel through an engine repeatedly for this purpose with engine > initially warm but not running.
