Just as I thought there could be no more new twists on the oil thread, here comes one!

You will tell very little difference, probably immeasurable, between checking the oil five minutes after shutting it off or checking it the next morning. There could be a few cars in the world that could vary more than others. It's more important to see that you check it on a relatively level surface.

The acceptable tolerance for oil level is between the full and add marks. This is usually a quart of oil difference. That's quite a lot of tolerance relative to the difference you will see right after shutting it off as compared to setting overnight.

Additionally most all MB's have at least 6 quarts of oil, making this MUCH less critical than some of the domestic and Japanese cars that carry as little as 3.5 quarts.

All that said, it's a very good thing that you are this concerned about proper oil level. It indicates that you want to take care of your car.
