I probably should have posted this under oil change stories.

I recently had my independent MB mechanic replace the rear diff mount on my 1973 MB 280 dual cam six with carb.

I had him or I should say the kid in his shop so an oil change. They used Castrol 20w/50. I was kind of curious why and he said that's what he puts in all MBs. I trust his judgement.

However, when I checked my dip stick later in the day, it looks like the "kid" overfilled my crankcase. It's about a quart over the max line. I'm curious....is this a big deal. Can it cause problems. It's probably coincidental but my car seems to be hesitating...not running as well.

Can either of these things affect my buggy?

I'm a novice here and appreciate your input.
