Arriver rapide et fidèle à la description

I've been using Marvel Mystery Oil for my air tools since the early 1970's when an elderly mentor told me to use it when I was a young man just out of the service on my first civilian job. It works fine and my air tools have always lived a long and useful life with out gunking up or showing much wear. It has never failed me. I also use it for a general light lube oil and when mixed with a little lacquer thinner it frees rusty bolts about as good as anything else I've tried. My elderly mentor had been a mechanic his whole life so the history of using this oil these ways has been well proven over time.

Works very well for gdi motors, which run well as faster speeds. This is designed for gas asperated, ekectric throttle body fuel enjection motots.would definitely buy it again.
