I think we need to get back to the first post. The request was to check the oil. The mayonnaise doesn’t mean the end of the world. Change the oil anyway and send him on his way. The less done to the car the better. Otherwise when the next thing fails our friend Lance’s good intentions will be on the hook. The car is being driven into the ground and the owner is going to change habits. Putting effort into the car now won’t change that.

Gift the guy a dipstick from a 98-99 E320 so he doesn’t come back.
