I was driving the car and it was losing power. On reaching destination. I checked the engine oil and noticed it had been filled well over the correct level. THis was checked with engine cooled down. Also noticed that oil appeared to be coming from air filter on crank case. No other indicators of engine problem, exhaust ok, idles ok but loses power when driving. Can anyone advise what damage can be done by over filling or how to rectify the problem such as drain oil, replace filter.......................
