JF Diesel Fuel Additive: Highly Effective Fuel Biocide Supplement, Prevents Corrosion of Fuel Tanks, Increases Lubricity, Dual Phase Chemistry | 1 Gallon, (BBJUG01US)

You can use this for gasoline also and it has been used in aviation fuel tanks too. Originally, it used to say that on the label, but you can still find it, if you dig deep enough into the specs on their website. It has kept my boat fuel tank clean for years and astonished my mechanic, when he changed the filters on my truck. The gallon size is cost effective if you use regularly.

FORGET all those other Diesel fungus killers, this is the only one approved by Mercedes, you add it and it kills the fungus, might take a few tank fulls to get it all gone but IT WORKS, remember to change the fuel filter after 1,000 miles or so .Great for Diesel cars, trucks and boats .WORTH EVERY PENNY ! .-Nate

Great price on great product

It did all I was told it would do, and plan on expanding into eight of my other stores. Can it be bought in five gallon containers.
