Default Overfilled engine oil is bad?


I got my car's engine oil and filter changed by a mechanic and it looks the oil is overfilled by about 1-1.5 cm above the max line on the dipstick. Are there any bad effects running engine with this much overfilled oil or should I unscrew the filter and drain some oil out of the engine?

Please help.

I didn't find the right solution from the Internet.

I think the biggest thing it would do is the crank would be in the oil. This wouldn't hurt anything, but it could make it sluggish. It's enough oil I think I would drain some out, but do it out of one of the drain plugs, not the filter. Since your mechanic overfilled it, he should be willing to fix it for free.

So others might chime in, 1.5 cm = .591"

If your oil level looks like this Ford say it's fine
