But I had a bad problem with algae in my tanks. This stuff worked the best out of all! This stuff is killer **Q: Does this treat Treats 1280 Gallons or 1920 as the Title says?** A: I put the hole bottle in my 2000 gallon tank. **Q: I have a 2006 peterbilt 379 with a c15 cat engine do i just open the fuel tank and poor an oz or do i need to inject the product somewhere else ?** A: just dump it in the tank, I think with 2 100 gallon tanks ill do about 9 fills, have extra filters on hand, you will need them. It will knock all that black crap out of the tank (algae) **Q: Will this work for gasoline algae** A: The website for the maker of the additive directly indicates it is also for gasoline. I suggest a look at the website and ignore the people that think they know what they're talking about. Algae is not necessarily in the gasoline but in the water that is in the tank and mixed with the fuel. "Kill bacteria and slime in your fuel on contact with FPPF Killem.
