Oil Changes 1999 ML320

Currently I am changing my oil every six months. The reason I do that is because I only drive the car 2000m per year and it sits a lot. I am thinking that I could change the oil once per year with no harmful effect to the engine. I use Mobil 1 sythethic. I would appreciate any advice from the forum. thanks. charles

Your thinking is correct. The nominal interval is 10,000 miles (follow FSS) or annually, whichever comes first. You could probably fudge some as well, but personally I would not.

Side note: At that rate of mileage accumulation, you must have the most pristine 163 on the planet. ;)

Good luck.
Check Codes: thanks for your advice. Actually I own a ML 320 and not the 163. It is in very good condition despite its age. charles
Actually, you do own a W163, which is the chassis designation for your SUV.

There is an excellent forum here full of good information aimed directly at your 163: W163 M-Class - Mercedes-Benz Forum

Happy reading! :D
