BIOBOR JF Diesel Fuel Additive: Highly Effective Fuel Biocide Supplement, Prevents Corrosion of Fuel Tanks, Increases Lubricity, Dual Phase Chemistry | 8 Ounce, (BB08EZ01US)

Excellent Product ! Works Great ! Worth the Money ! We Recommend it to all of our customers.

Works great, I use it in my 500 gal tank, once a year, first time I used it was on 5yr old diesel, fuel was clear 36hrs after treatment. For maintenance I use it once a year, my average yearly consumption is 75-100 gallons.

My diesel pickup sits more than it's driven which we know is bad on many levels. With all the garbage in biodiesel, this is a must have product for me. My state requires all diesel to be bio. Last thing I need is some science project to be growing in my tank. Lasts a long time at the required dosage. Sometimes,the dose is small so I put this in the funnel first and flush it through with my dose of Hotshots EDT before filling the tank. Never clogged a filter with this in the tank. Also used for diesel generator fuel that sits for a looong time sometimes. Never a problem. People will tell you, you don't need this. Maybe not with premium fuel or if you run through your fuel regularly. In my case, it's cheap insurance.

I added this to a transfer tank after noticing a small blackish color glob in the bottom. I checked a couple months later and the area turned grainy and had no more growth or any new areas of concern. Definitely plan on using in every tank from this point forward.

Arrived well shipped got the slime out like no other stopped the chatter in the fuel pump. bottle is tough well designed no leaks and easy dependable measure and cap

Using in a 500 gallon off-road diesel tank. We have had problems with algae which might come from our supplier. What a pain! Changing filters on equipment way to frequently. This product does the job admirably. Unfortunately we have to time the fill to allow for use of the product, but well worth it.

Seems to have cleared up my cloudy diesel

It works good for diesel fuel and injector fuel additive
