Is it ok to overfill your car with motor oil?

the oil level on the dipstick is one inch over the F lineIs it ok to overfill your car with motor oil?
As mechanic you don't want to put more the what fills it up to the full line, a hair bit more won't hurt but that much is a bad call on whom ever did your oil change and could very possibly cause sever damage to your engine. From lifter's to seals, even bearings. The first thing to usually go is a main seal of the engine, like a rear main or engine seal internally. Which is a major expense. Go back to where you had it changed and make them do it right this time! Then take it to another place for a free inspection.Is it ok to overfill your car with motor oil?
no that's way too much oil in your engine as some others have mentioned it will whip your oil up and go frothy and this oil doesn't make a good lubricant it's not good for the engine, best to remove the sump plug and let some of that oil out slowly to get it to the correct level on the dipstick. Buy some oil just in case you let out too much oil and top it up a little bit at a time so you don't go over the full mark again...
no horrible idea, you need to make sure it is what the manufacture recommends because if you fill it too high you will have high oil pressure and also can ruin many parts such as bearings and you could also possibly lock up the engine
No.


In some rare cases, the crank shaft will whip the oil into an aerated foam which isn't a very good lubricant. At a minimum, the oil will impede the crankshaft and cost you a few horsepower.
Yeah its ok, as long as you dont mind eventually blowing your engine up.
Best to stick with the manufacturer's recommendations.
my experienced opinion, a half a quart only
