I have a 300E Mercedes 1989

Asked by Jan 12, 2015 at 06:01 PM about the 1989 Mercedes-Benz 300-Class 300CE Coupe

Question type: Maintenance & Repair

I was told that it is not a good idea to switch from regular oil to synthetic, was told it might create leaks and damage the engine.
Your feedback is appreciated.

synthetic is always good for an engine. HOWEVER, a high mileage engine that is used to regular oil will likely have high oil consumption if you switch to Full Synthetic. Try a synthetic blend first. It will still benefit the engine, but not cost as much. A common type is 5w-30w.
