Problem I see (or my theory) at most dealerships IMO they (some of the mechanic's) don't know how much oil to put in. thinking every thing holes 5 quarts. so if your 4 cylinder holes 4 1/2 quarts you get over fill by 1/2 quart. Really no excuss. if you change oil every day you should 1. know how much oil to put in. 2. Check the oil level when through. 3. DOUBLE CHECK oil level and look for leaks after shut down after the oil change. Which I bet 2 and 3. aren't done either and that's why NO 1 gets overlooked. Then the desk jockey has to put up with the aftermath when caught! Which is probably rare cause nobody follows up on service preformed'
Maybe IMO 1/2 quart won't hurt, but I wouldn't want Full quart over. Even though it won't blow the engine up it still would probably overheat and put undo pressure on the seals. SO IMO at 90K more or less oil leaks maybe worse than normal??? my opinion of course.
I bet management or service supervisor had little Talk to the mechanic's after this incident. Hopefully it won't happen again there. Others should thank you for bringing this up again. Last time was 2012.
