Did I overfill my oil ? Consequenses? solutuions?

Did I overfill my oil ? Consequenses? solutuions?

So I changed the oil in my 2005 997s. I drove the back of the car up on ramps and then unscrewed the drain plug and let it drain for about 20 minutes or so. I changed the oil filter as well. Replaced the plug with new washer and then filled it back up with 8.25 L's of Mobile 1 0-W40. I thought better to underfill and add more later. So I drive the car around for a but and then find a nice flat surface to check the oil on but the electronic check says it's ABOVE full !!

I'm a little worried. Anyone know if there are consequences or am I just worrying too much. My only thought is that I didn't let enough oil drain out (oil wasn't warmed up enough?) or that since the rear of the car was up on ramps all the old oil didn't drain.

Should I re-do the whole oil change ?

Who's the expert ?

The ramps is most likely the cause of the over fill. It's hard to say how over full it is right now. You can remove the oil filter canister and drain out a few hundreds of a ml and recheck the level. It's best to let the engine sit for a few hours to cool before checking the level.

Anyone try siphoning oil out the top ?

If you changed the filter as well you should be just fine.

If you didn't (change the filter) then I think you did overfill and need to drain some out.

I did change the oil filter... but it was still way over.

Your 997 oil capacity with a filter change is 8.7 quarts, correct? The GT3 is 9.3 quarts I believe...not sure if I have the fill capacities correct. I'm going off memory.

If you installed 8.25 Liters, you installed 8.72 quarts (just slightly above the capacity). If you were on ramps, and really out of level, you might have some oil left in the sump, but I wouldn't think enough to cause the situation you are having.

I know you mentioned you may not have had the car warm enough when you did the oil change. Did you have it warmed up? Did you allow the oil to drain for at least 20 minutes?

Over capacity would drive me crazy as I think it is you too. If you have a MB shop close to you, they can siphon a little out for you and I'm sure would probably do it complimentary knowing your circumstances.

Good luck.

Well - I purchased a pump at my local Kragen autoparts store and stuck it into the oil fill pipe and drained out about 3/4 of a L. Oil level is perfect now. Next time I'll put the car on jack stands to get it level before the change.

Thanks for the great post and pictures showing how you recovered from the overfill. I would have never imagined Kragen had a pump like that you could adapt to remove engine oil. Nice work!
