Diesel Biocide Additives?

I was and am curious just how many of you have used and do use any type of Biocide to keep all the green slimy stuff out of your diesel fuel tanks?

Do you think this product is necessary in a daily driver pickup?

My 7.3L just turned over 287K miles and I have never added any type of Biocide to my fuel tank... I just wonder if I need to invest in a 16oz bottle and treat my fuel system?

Does anyone Know---->What is the main cause of bacteria and fungi within the fuel tanks?

Just trying to gain more knowledge on this product and subject...

Thanks SyN

My guess would be from the water in the fuel

Re: Diesel Biocide Additives?

If you aren't having trouble you don't need the additive. It is only if you have the fungus in your system. If you buy good quality fuel from a reputable dealer you should never get it. It tends to grow in fuel that has been in storage for a long time especially if moisture was able to get with the fuel. We sell premium fuel that is supposed to keep it from ever starting to grow. I have never had it in any of my customers in 7 years of fuel hauling. The only thing I have heard of was a piece of county equipment that had sat for 6 to 8 months after they bought it. They just had to drain the tanks and replace filters and it was good to go.

Re: Diesel Biocide Additives?

the way i understand it is that if you live in a state that requires so much % of bio-diesel in the fuel they sell, then it may be needed. we run 4oz of john deere's biocide in our machinery every week in north dakota. it may be a ploy, but the parts guys tell us that if dont it will gum up the fuel lines.
