Prevents and kills the diesel fuel bugs
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.

Solved my hydraulic issue!
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!
