Quick oil level question

[Tom]

Last week when I changed the oil I overfilled by almost 1/2 quart.  Could this cause damage or should I let it go?  Thanks.

[Run Away]

I give it about 4 days.

[Run Away]

Seriously though, no harm done at all.
It'll just end up burning off over the next month or so.

Agreed with above...


*how'd you over fill by a Half-quart...

[Tom]

The thing is the engine doesn't burn or leak any oil.  It will be just as high the next time I change it.

He put a pint more in than was specified...?

[Tom]

Does anyone know if having a 1/2 quart more in the crankcase can damage an engine??  I wouldn't think so, but better safe than sorry I suppose.

It won't be a problem, I always overfill a bit.  This way under hard cornering I'm less likely to starve the engine.

Ok, thanks.  I'll just let it go.

It might cause you a little fuel mileage as well from the crank whipping through the oil. You won't do any harm unless you hammer the engine enough that the crank actually whips the oil into a froth.

Thanks.  Wouldn't this happen, though to a lesser extent, if the oil was not overfilled?

I overfilled my lawnmower's oil by quite a bit and nothing has gone wrong all summer.

A little extra oil never hurt anything...Since lawnmowers tend to burn oil a little

Not the Deere.

No offence, but I've filled a mowers crankcase with water and it it still ran..

That's some good stuff.  I'll make sure to check it out in depth in the morning when I can concentrate.  But for the record, I've killed a B/S motor

Typically speaking? No. Most oil pans are deep enough that it isn't that much of a problem except if you're in the habit of running the motor at 5000-6000 rpm all the time. I skipped on putting a windage tray in my SVO simply because it wouldn't have much effect at the engine speeds I'd be at most of the time.

A half quart over should be no problem.  But it is possible to hurt an engine with too much oil.  My 2.7T is notoriously sensitive to too much oil. It's been known to blow seals and mess with emissions stuff.  Other engines I've heard it can mess up your PCV valve, etc.  Just be careful out there!

[BartsSVO]

Excess oil could perhaps get sucked up through the PCV valve, but likely wouldn't damage it unless the car was infrequently driven and it just sludged up. Most vehicles have a baffle where the PCV valve/hose connects to the block or intake to keep them from sucking up oil though.
