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

Works great! Killed the algae that was in my tank

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

For my system it took about three capfuls and two filter changes. But the stuff works and it's much cheaper than power service by far.

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

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.

Used this in August 2017. Added this, plus stabil for diesels and Ford cetane booster and filled up a 40 tank....drove around to mix it up and run it through the lines.Put my truck in a dirt/gravel storage lot. Disconnected the batteries. Put a lot of moth balls and eucalyptus oil in containers under the hood, in the passenger compartment and in the covered bed of my truck.Now it's mid May 2018, nine months after storing my truck, and my fuel is good too go, started up my truck (used a portable jump starter) for some extra juice.No critters invaded my truck (Arizona) and it's running like new. Just had an oil change and fuel/water separation filter change too.A combination of all these steps saved my truck! Highly recommend these fluids.

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

I store my diesel motor home in hot humid Florida. Without Biobar, algae will form in the fuel tank and very expensive and time consuming to get it cleaned out. Won't park for more that a few weeks without it. The one time I didn't algae caused almost $5,000. in damages for the new purchasers. He waited 3 months to pick up the motor home with no fuel protection, big mistake burnt up main and boost fuel pumps as he drove to Cummins instead of changing filters. Biobor JF is very cheap insurance.
