JIffy lube put 3/4 of a quart too much oil in my wife's car, takes 5.5qt and they put 6.25qt in the engine. She drove it about 100 miles before I caught the error. We took the car back to jiffy and had them drain it out.
Car runs fine, but how would I know if there was any damage to the crank seal or anything else? What is the root cause of problems due to too much oil..oil pressure too high damaging seals/bearings?
This is a 9k mile brand new engine and I need it to run 250k miles, I am now concerned that this stupid error has compromised the engine.
3/4 quart didn't do anything. All it did was reduce fuel economy because of drag on the crank. I used to overfill my Honda intentionally by almost a half quart. Did that for 20,000 miles and totally ran perfect. Every time the motor was out it looked great.

I use a full 6 qts, in my car just so I don't sit on half a quart for 3k miles. no problems with fuel economy or power...now needin a new clutch...that's the only thing keeping me from going fast Where's Scoggin Dicky when I need a deal
Any problems due to high crankcase pressure would have shown up right away. So it was not overfilled to the piont that causes damage. This is not something you want to find out where the tipping point is.
