    For our big EFI engines, we use a recommended quart of TCW3 to three gallons of gasoline for storage mix, with some stabilizer….What’s that? 8:1? We drain the VSTs down and make sure the mixture gets all the way through the motor. The plugs get a little fouled but there is no noticeable smoke. It is kind of amazing.

    Long live American manufacturing!
