See it happen lots of times. Its does NOT mean you overfilled the oil tank, having oil backup on the filler when filling has nothing to do with the oil level, other than your tank is getting full. The best way of checking the oil level in the car is to have the car warmed up (min 1/3 up the temp gauge) and use the dipstick while the engine is idling, and on a level surface. Only if the oil is over the twisted section of the dipstick are you really overfilled and need to drain. Conventional wisdom is to put the oil level 1/3 up the twisted portion of the stick, this allows for oil expansion and leave plenty oil in the engine.

So, have you truly overfilled your tank, or you just overflowed the fill spout when filling the tank? Overfill may mean removing some oil, overflowed means just a mess. I hope that you get that these are very different.

Cheers,

Mike

Oil in 993 is like syrup, my father in-law who helped me fill my 993 after oil change could not believe how thik the oil is. Took a while to pour it all in.

Thanks
