as my fellow colleagues have noted,, Techron is the bomb... It's the only thing I will pour into my tank as a "cleaner/preventer" for gummy gas...
I do use IsoHeet, regularly, when I think I have water issues...
BUT, I never "mix" the 2 in the same tank, I make sure to get rid of water, with the IsoHeet, run the tank empty, and fill the tank with good fuel again, (I can get "pure"gasoline here), and then when the tank gets down below half, just on straight gas, do a refill, and dump a bottle of Techron in.. yes, I do a full bottle (but then I make sure to run that full tank out... just don't dump it in, and let it sit.. that does nothing good...hell, do we need an
excuse for riding 230 miles, in a day?.. that's silly... go ride.."honey, I gotta go clean my fuel system, I'll be back in 6 hours (meaning really 3-1/2 hours...heheheheh)..."... "ok dear, have fun"...) Makes for stinky riding,
as it does clean, and ends up as smelly exhaust... but it's goooood. Heaven help anyone that follows you on a ride..
I miss Chevron gasoline up here in Ohio, always loved using it down in Va., and would go out of my way to get it....
