Keith THAT is funny Keeps your valves from sticking!

I got sold on MMO years ago, it does really help with today's dry gasoline. I don't think anything over 4 oz. per ten gallons will hurt a thing.

I buy it in gallon jugs at WalMart, Farm and Fleet, Farm King, whoever has it on sale lasts all season.Good stuff.
