Fuel additives

I had been wrestling with fuel problems (dirty Racors and engines shutting down) all last season so after I put Callisto up on the hard for the hurricane season in Sint Maarten I had a fuel guy come out and clean the tanks and polish the fuel. I have always faithfully added Biobor JF and Biobor MD every time I fueled. My fuel guy is telling me that the additives are causing the problem and I would be better off not adding them. Do other people agree with not adding the fuel treatment additives? I thought everybody put in some kind of fuel treatment additives to control algae growth.

Re: Fuel additives

i've used the biotoxin in the two 50 gallon diesel tanks for 17 years now, no problem for the ford lehman. i also check with a turkey baster and 2 foot of hose the bottoms of the fuel tanks and suck up the very bottom to see if it contains water and or sluge. so far no problemo

Re: Fuel additives

The only thing I add is a cetane booster. Contrary to mythology, diesel ages poorly and can be “too old” and many people up north suffer the consequence because they keep the tank(s) full when wintering. If your tank has fresh fuel and you preclude moisture, additives aren’t necessary

Re: Fuel additives

Storing diesel fuel over 2 months in warm climates/3 months in cold, add a BIOCIDE such as Biobar JF to prevent algae/fungus growth.

And, when storing fuel, fill the fuel tank FULL to minimize condensation.

"... Contrary to mythology, diesel ages poorly and can be “too old...”

no, sorry, Total guarantees its diesel only 6 months
new diesel contains more products of vegetable origin, less stable, and less sulfur which is toxic for bacteria
no, its not a "mythology" ...
