Thanks for the info BigBear. I have never used MMO, but picked some up today on way home. I usually put SeaFoam in the OPE gas. Usually about an ounce per gallon. MMO is about half the cost and I have heard good things about it.
I did notice that Sta-Bil marine states on it's label that it protects against ethanol.
How much MMO per gallon do you suggest for OPE?
BTW, my truck is Flex-Fuel capable, I just run Techron in the fuel, every Oil Change.
