Bactericide in diesel

Yahoo Message Number: 21442
Changed my fuel filters and found some green/brown slime on one of them. The filter had a very small amount of water in it (1/4-1/2 cc) when I dumped out the diesel in it. Has any one used a bactericide diesel fuel additive? If so how did it work? Did it clog up you fuel filters and how many fuel filters did you have to change before you stoped having problems?
Thanks

Hello Calvin; YES, I use a bacteriacide in my fuel with every fillup.
I think it is critically important. The big over-the-road trucks go through so much fuel that they usually don't have a problem with algae growth in the fuel, but as a motorhome owner, I know that often it will be months between fuelings, especially during the winter months.
So, we ALWAYS use Pri-O-Cide with every fill-up during every season.

Likewise, I use a fuel life extender called Pri-D because sometimes I'll have a tank of fuel that may just sit there for 3 or 4 or 6 months. Pri-D is what the hospitals use on their diesel generators to ensure that the fuel is fresh and will start their critical backup generators when needed.

Lastly, the new low sulfur fuels have a very low lubricity factor and will cause excessive fuel pump and fuel injector wear, so I use an "upper end lubricant" additive made by Lucas to eliminate these porblems. This additive can often eliminate engine smoking too if you are having that problem.

I buy my Pri-O-Cide and Pri-D from Slidell Marine. Their web site has some EXCELLENT information on it regarding these products. Click here to learn more...

I use these 3 additives with every fuel up. When I remove my filters and cut them open to see what's inside, I have never found any slime or sludge or algae.

I know it costs a about a buck more every time I fill-up, but that is a small price to pay to ensure that I never have a fuel related breakdown when traveling.

I have a '98 Magna that I bought in '04. The unit had water in the fuel tank and in the summer of '05, bacteria began to grow. I tried having the fuel tank pumped out and treated to no avail. Continued to have breakdowns every 100 miles or so. A real nightmare. I also had rust in the tank from the water. I finally had Buddy Gregg remove the tank and have it cleaned and re-lined before the problem was fixed.
My advice is to treat it aggressively and carry plenty of filters but it took major "surgery" to fix my problem.

Good luck,
Bob

Thanks for the info

I do not think my problem is that bad. I think the water I have is from condensation, not bad fuel. I plan on haveing several fuel filters and treat the fuel before my next trip. I plan on going on a trip in two weeks that will use the old fuel up. Then I will find out if I have a nightmare or just an isolated problem.

Microbicide usage in diesel fuel

Most coach owners don't realize they have a problem until it's too late. Every fuel tank expands and contracts as the fuel is heated and cooled. Just running the engine for a few hours circulates fuel and heats it as it passes through the fuel pump so that after a few hours the fuel has expanded and is warm. Then when the fuel cools, it draws moist outside air through the air vent. Then this moist air condenses, the water accumulates in the bottom of the fuel tank. After a few years, the water level gets deep enough to reach the fuel pickup tube and then the microbes will be sucked into the fuel filters and stop the fuel flow. That's when most coach owners think of starting to use a microbicide -- BUT it's too late as the damage has already accumulated in the bottom of the fuel tank.
Sometimes pulling the drain plug on the bottom of the tank and flushing it with fresh fuel can abate the problem... then the owner must start using Pri-O-Cide or some other microbicide to prevent a reoccurance of the problem.

So, as they say, it's "Pay me NOW, or Pay me Later"... but sooner or later this issue will affect most motorhome owners who travel in humid places, keep their coach 5 years or longer, and do not use a microbicide.

When will you pay the piper?

Be sure not to use anything but truck stops such as Flying J, Burns, Travel Plaza etc. Do not go into a regual gas station they do not turn over enough diesel and this is the source of your water.

Will a separator filter remove enough water from fuel to prevent bacteria problem?

I have considered adding a pump & separator filter near fuel tank.
Purpose would be to get water from fresh fuel & get water from bottom of tank. It would draw fuel from bottom of tank & return to top of tank thru genset return line.

Would this be enough or would water return to tank thru separator filter?

Caterpillar C9 has no return line. Fuel goes to engine once.

Can we use any bactericide found in any Truck Stop (i.e. Flying J, etc.) or should we look for specific kinds? Thanks...
