how much damage can overfilling engine oil cause?

>>16931718
Can create a fuck ton of crankcase pressure, won't lube properly and probably blow out some seals

Much. Too much oil can cause sloshing, then foaming. Foam is your worst enemy.

>overfilling engine oil
It fucked my lawn mower for good.

>get a dealership oil change 3 months ago
>check oil for the first time today and it's way over the checkered line

I've owned the same Toro lawnmower for 18 years and only changed the oil 3 times. And the mower was made in 1991.

It runs like a champ. 5 years going since the last change.

You must buy shit products.

No thank you sir.

Car buying story
>drive two hours to go look at a car
>2008 Nissan Xterra
>Dealership looked a little sketchy when my buddy and I pulled in
>Decided to go look anyway
>Car is in decent shape inside and out
>Decide to test drive
>Start going down the road and realize that the oil pressure gauge is all the way to the top
>Pull over to look at engine
>Sales guy that was with us says it's probably broken
>>probably
>Look under the car and notice there is a crack in the engine block that was dripping oil
>The fuckers filled the thing with as much oil as it could hold so that the oil pressure kept oil from shooting out of the engine block
