BIOBOR JF Diesel Fuel Additive: Highly Effective Fuel Biocide Supplement, Prevents Corrosion of Fuel Tanks, Increases Lubricity, Dual Phase Chemistry | 32 Ounce, (BB32EZ01US)

Based on 4 years of experience with this product, it appears to be a very effective biocide supplement. Our 800 gallon capacity tanks were significantly fouled when we purchased the boat. BIOBOR has essentially eliminated the fouling and maintained the tanks clean. Additionally the bottle is the best and easiest method I have seen to measure and dispense the product.

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!

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

I have a fair amount of experience with marine diesels and this additive is absolutely essential in my opinion for your diesel fuel. In fact, I consider it essential in all diesel fuel regardless of what the engine is powering on land or water. It kills the micro-organisms that turn into a slimy, snotty, blob usually associated with water or condensation build up that could be growing in your fuel tank that your unaware of untill it's too late. With plugged up fuel filters, injection pump, or worse, it could be a very expensive repair or a least a major inconvenience at the worst possible time. Biobor takes care of that. The nice thing is it doesn't take much, a little goes a long way. I have used it at every fuel up for over 28 years and have never had a fuel related problem with any of my diesel engines on land or water. Just service your fuel filters regularly and you're good to go. Pretty cheap insurance if you ask me.

Started using this because the inside of my 125gal tanks on my Freightliner Columbia is contaminated with black algae. I've giving it the shock dose which is 3oz per 125gal. I can see the black speck in the filter floating around so it's working. The filter getting black as well. I think I just need to have my tanks steamed out. Also I'm not 💯% sure but my truck idle is not as smooth as it used to be since adding this. I'll update this once I'm sure.

excellent diesel additive, highly reviewed, works as expected

It doesn’t let algae grow in storage tank Works as described

I run a WVO/diesel blend in my old Benz, and was plagued with mold growing in my prefilters to the tune of having to change them every other week. It was getting expensive. I researched this product and gave it a try. Almost immediately I found that the prefilters were lasting almost two months. Yeah, I have to change them more often than I would if I were running straight diesel, but WVO is free so there is a trade off here and it's well worth the cost of a few filters. I use a cap full of Biobor for each 5 gallon cubie of filtered WVO which is almost exactly equal to what the manufacturer's recommendations are. I expect this 32oz. bottle to last more than a year running two vehicles. Well worth the investment.
