Gassers don't mind, in fact it used to be common to overfill cars with straight sixes and a pan without baffles if you were cornering hard. Well, american cars. One quart is probably not going to make a difference. If the oil level makes contact with the crank, the oil will break down incredibly fast from sloshing. Other badness is possible if you're really unlucky. A diesel will run itself to death off crank slosh, as the engine is quite happy to burn oil as fuel. K
