My mechanic changed my oil and put about 1/2 a quart too much. Can this damage the engine? Should I drain the extra or just leave it alone? The car is a Chevy Malibu 6 Cyl.

Is too much oil a problem?

I knew a mechanic who intentionally ran his 1.2L Civic 1/2 a quart over for extra protection.
He also had a Weber carb, performance cam and exhaust header.
