Strafzettel

2 days ago I had a B-Service done at Mercedes of Chicago and today I checked how much oil they put in the engine. I checked after the car had sat over night and after I drove it today and both times the level was above max. I called the dealer and they said to come by and they would correct it Has anyone had issues because of overfill?

Overfill actually is Bad - have them adjust soonest at no charge - it happens at some shops in Winter - proper spec is to run engine to operating temp 1st - then pump out the oil - warm oil flows down from the head/block channels more smoothly - cold oil tends not to film/stick up in the engine channels (like cold oil should) resulting in about 1/2 qt less drain out - tech's full spec - yep, overfill..

You will be running it into the dealer warm... they will take it in warm ... all will be smooth when they pump out a bit-at-time - a 10min shop thing max..

They all look like that on the GLS...its fine as the long its not too far above the red plastic tip

I believe it should be in between min and max, not 1 centimeter above max

Good thing is GLS does not burn through oil like MB V6 engines....I had a GLE 350 that ate through a quart once very 3 months

This is my 3rd MB with V6 engine since 2011 and I never had to top off the oil
