this thread makes a great case for learning to do a DIY oil change on this car.

The first time I had my oil changed by the dealer, the same thing happened to me. When I got home, I loosened the drain plug, so it was just dripping. A hour later, I re-tightened and it had drained a 1/2 quart and the level was one bar below.

Almost everyone who gets the oil changed at the dealer will have the oil a little overfilled. They just pour in a set amount, but rarely do they wait the alloted time to allow all the oil drain out. After watching the tech change the oil, I do all oil changes myself and don't have to worry about overfilling.

Relax. Much fuss about nothing. Most dealer refills will read full = or one bar over. They add a measured amount - it's not guesswork - and there will always be some oil left in the system hence the slight overfill. It's marginal, normal after a service and your car will soon burn it off (and quite quickly given some of the other threads on here!).

See owners manual.

I would not fret it.

The Electronic Measurement is more of an approximation than an accurate system.

Showing "over-full" could be a result of 1 or 2 oz. of additional oil triggering the sensor to the over-full indication.

I posted an update but for those that missed it the dealer took out about 3 teaspoons of oil and it dropped to one bar below full!
I was considering changing the oil, i like getting my hands dirty, but for resale i decided to just have the dealer go ahead and do it.

cheers

Three whole teaspoons? Should have put it on a flat bed and dialled 911. Glad they managed to save the engine!

My sensor seems to fluctuate between overfilled and not overfilled depending on its mood. I don't put much faith in it anymore which begs the question "Why didn't Porsche give us a manual dipstick?"

Your observation of full bars indicates just that - full condition. That's what they're trained to do - to fill it up to full.

You can take it back to Newport if you like. But you'll end up just wasting your time.

I don't know about Porsche...but at Mercedes no one sits there opening up individual quart bottles. These are bought by the drum and they certainly can be adjusted to a fraction of a quart.

I'd sell it pronto. Sounds terminal to me. Most engines never recover properly after a three teaspoon overdose. I sold my S after overfilling the front tyre by 4 PSI. Well, you can't be too careful - I may have buckled the wheel.

Do you think i should disclose the fact that the engine may have been terminally damaged to a potential buyer? I know i will probably take a big hit $ wise, but i want to do the right thing?
I also used a non P leather conditioner the other day which im sure wont help either.

Thanks for any advise.
