Junkman, I know that most of the guys working in those places know what they're doing, but I just could never get myself to trust them. When I was about 18 and my Dad owned a service station, we hired a guy who said he was experienced at oil and filter changing, and greasing vehicles. And he did all right on the first few cars, then he had the mayor's new Oldsmobile in for an oil & filter change. When he let it down off the lift, he came inside and told me the car started OK, but wouldn't back out of the bay. He had drained the transmission and added 5 quarts of oil to the crankcase! /forums/images/graemlins/frown.gif We told the customer what had happened, but fortunately the car suffered no ill effects.
