Join the Mobil One club and get about $1 per quart rebate. You have to buy in multiples of 6 quarts though.

Somewhat related since I just bought a '99 C280... I checked the dipstick and noticed the oil reached a few mm above the MAX line. Should I siphon some oil out or should I not worry about it? The oil was still clean and the car was just serviced less than three months ago so I don't feel the need to do a full oil change.

If it is high when engine is cold, siphon it down. Develop a routine for checking the oil with car in level place and after cool down.

Just a follow up, it's been over a week since I changed the oil and it only really needed 7 quarts. I probably could have put in 8 with no problems but at 7 it's right in the middle on the dipstick.

7 or 7.5 qts is about right. It really depends on how long you let the old oil drain. Full 8 qts will normally be too much. To be safe, go with 7, drive for a week and then check and adjust as needed.

1998-2000 C280s all have the same M112.92 engines.

Oil capacity is 7.8 liters or 8 1/4 quarts. With a new oil filter and depending on well it has been drained, you'll need 8+ quarts. Just go by the dipstick and try and be consistent in when (overnight) and where (on level spot) you check.

Glen, The specs are probably right and I am not disputing it. But as you and I have hit the nail on the head: "It is how well you drain out the old oil".

You definitely do not want to over fill.

Just two weeks back I did an oil change on my 1999 C280 at my friendly indy. In our conversation we lost track and put full 8 Qt. Guess what? It is over the full mark on the dip stick.

Therefore, it is prudent to go slow and you can always add on later.
