What is the best to clean out the algae ina diesel fuel

I don’t know which is the best. But I had a bad problem with algae in my tanks. This stuff worked the best out of all! This stuff is killer

Does this treat Treats 1280 Gallons or 1920 as the Title says?

I put the hole bottle in my 2000 gallon tank.

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 ?

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)

Will this work for gasoline algae

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.

Will be buying more to add regularly great product

This stuff is great I have been fighting bacteria in my fuel tanks on 2 trucks . The filters would turn black in minutes after charging them . I added 5oz to 200 gallons and cranked the truck it ran for 5 -10 minutes and the filter was clear . The filter was black before it had 600 miles on it . This stuff really works .
