JF Diesel Fuel Additive: Highly Effective Fuel Biocide Supplement, Prevents Corrosion of Fuel Tanks, Increases Lubricity, Dual Phase Chemistry | 16 Ounce, (BB16EZ01US)

I've tried several products to keep the bio goop out of my disel cans and tractor tank. The crud is apparently in my local fuel supply and a given it would show up every time my cans were filled. Just a very small amount of this treats a 5 gal can and it really works so much better than any other additive for stopping and preventing the goop. This isn't a water preventor or anything like that. It actually works on minmizing and stopping the microbial growth - fungi and bacteria, in the fuel. I had a bad contamination show up in my tractor tank and I was getting plugged repeat offenders (blockage) of fuel line and filters. Once I finally got that stuff out of the entire system, Biobor JF has killed off any residual and prevented this from reoccurring again. I have taken an extra step and added a double filter on my funnel to catch any other non-fuel things that make it into the diesel. The problem seems to be solved.

Exactly as advertised

Haven’t changed my primary fuel filter in my marine diesel engine in 7 years.

Ordered March 31st, delivered April 21st.I haven't used it yet, but it should do what I need.

Works great! Killed the algae that was in my tank

Have been using this for years in diesel boats. My most recent boat was purchased in Florida and the fuel had a lot of growth. Racor filters would tun black after only a few hours of running. After using this additive with each fill up for a couple years now, I only change Racors once a season and they stay relatively clean.

In my case, it needed several tanks over time to fully eradicate the algae problem.

I dump this in the diesels I don’t use often to mitigate water
