How much is Overfilling?

If the top of the oil pool comes in contact with the crankshaft counterweights while the crankshaft is spinning, that's overfill. How much oil does it take to get to that condition? It depends on the configuration of the oil pan and its relationship to the crankshaft.
I would jump at the chance to see where the oil line is on my car because I run 6 quarts (recommended fill is 4.5 quarts). Going by engine performance alone, it seems as though the oil is staying clear of the crankshaft.

There is a full mark on the dipstick, over that is overfull. I wouldn't put more than that in my motor. Although it may never hurt anything.
I'd say a half quart over the full line would be considered overfull. It's not likely to hurt anything unless it's drastically overfilled though, as Merkava said, where it comes in contact with the crankshaft and causes bubbling, etc.
Wow!
I fill mine alittle over the full mark on the stick. Book says 5.8 i throw in 6 and its still over the full mark even with a oversized filter.
A half qt over is OK on most cars.
Try to get it right, of course.
Some autocross guys overfill their engines a bit on purpose, to keep oil at the pickup in harsh cornering conditions.

I agree, i wouldn't go any more then that,i always over fill mine 1/4-1/2 qt.
when your engine is running allot of oil is pumped out of the pan and up to the top of the engine,so i don't see or have had a problem with it..
I don't like the idea of overfillin'....extra oil might slosh around and make it hard to turn left!
Just curious, because it sounds like you have never looked at your dipstick. Do you check your oil level? Do you just overfill by this much because your car burns oil?
It seems like there is one in every forum!!!
No...it's right
I've never done this, because I've never raced my Corvette. But the owners manual instructs you to add an extra quart of oil if you are going to race the car or operate it over 150 miles per hour (as well as xtra air in the tires). When done you are to drain it and go back to the normal fill. So at least in that vehicle (LS2 engine)there's room somewhere.
I have a tough time reading my dipstick. On my Avalon, it is so skinny and picks up so much oil going in and out the tube, it is hard to see the actual oil level. I'm tempted to put in an extra 1/2 quart since it specifies 6 1/2 qts with filter.
why is that with the corvette? does it burn when it runs that hard?? i would assume so but i am not sure... can you give details on why? just out of curiosity
Okay this sounds a little techno geek, but the only true way to find out if you overfill is to measure the sq in of your pan and find out how much it rises per ounce or something like that. On average, there is about one to two inches between crankshaft and proper oil level to allow for hills and grades. To me if a manufacturer specifies a certian amount of oil in the engine, I stick with it. Anything else is risking it. Unless maybe like what ARB1977 says and it's just an extra .2 qts on a big engine. I knew a guy who added an extra quart to his engine for extra lubrication. He couldn't figure out why his lifters tapped on first start of the morning. The first start was in his driveway with a steep slope. I told him to just fill to level. The lifter noise went away. IMO, I'm not going to challenge the engineers on this one unless I go with a deeper pan.
ADD 1 QT|. . . . .|FULL
My oil level comes to the last 'L' in FULL
My car and truck are both in excellent condition and consume no oil. I run the 6 quarts because I believe more oil is easier on the oil itself.
If you were to single out one singe oil molecule, and a reference point within a complete loop for the molecule to pass through during circulation, that same molecule would pass through the reference point fewer times with an increase in oil volume because that molecule would have to wait for the other molecules to pass by the reference point first.
That reference point could be a chain link in a timing chain that has a tendency to "squish" the little oil molecule as it comes through. If the same little oil molecule is able to pass through less frequently, because he has to wait for more of his buddies to pass through the chain link first, than he gets sent through the chain link fewer times during an OCI.
Well done, Merkava 4.

You convinced me! Imma fill mine up to the rockers!
