The gasoline however, tears the oil apart - destroys it. That's why the oil turns into sludge. It's the same thing if you where to drive 50.000 miles on the same oil. Once the additives and molocular structure of the oil, can't stay together anymore, you'll get sludge. The gasoline does the same, just more rapidly... > I have heard of sludge problems on the 4 cylinder engines ever since the > recommended oil change interval was increased.
