Hammonds Biobor JF, Diesel Fuel Biocide - 32oz

Top-of-the-line product to keep your diesel, fuel free of algae

excellent diesel additive, highly reviewed, works as expected

One of our tractors kept getting milky looking hydraulic oil, even after multiple hydraulic oil changes. I added one half of an ounce of Biobor JF to the 15 gallon hydraulic system when I changed the oil last time and the issue has not returned! Before adding Biobor JF, the hydraulic oil was growing algae and plugging up the filters, usually in just a few months and very few hours. It's been over a year since I added Biobor JF and the hydraulic oil still looks perfect! Hydraulic oil and new filters are expensive. Biobor JF has saved me a lot of $ in fluid and filters already, not to mention the time and headache of having to change it before it should be due!

This worked well to get rid of bacteria in my fuel and lines. Cleared up years of weird problems in just 4 tanks. Saved thousands in unneeded repairs. Very happy.

Small amount needed for a full tank so should last a long time. Hard to say if it works, better safe than sorry. My truck is only occasionally driven so fuel sits in the tank a long time. Algae growing in the tank would clog the fuel system and be an expensive repair.
