Sheesh! Just tried to change the oil on my old Chevy. Easy, huh? Wrong. The last person to do it (not me) managed to round off the drain plug so no wrench will fit it. I can’t grind it off because my neighbor borrowed my grinder and left town. What kind of moron does it take to bugger an oil drain plug? It’s easy on Fords, their plugs are made from pot metal and are designed to be easy to strip or round off. A Chevy plug though is forged steel. To round it off you have to work on it hard with obviously wrong tools. Idiots.
