I'm having 150 gallons of diesel fuel delivered today. I use it in my tractor, gator, and generator. I expect this to last me 3-12 months depending largely on how much I have to run my generator. Do you guys put any additives in your storage tanks?
Ask the supplier that you bought it from. A couple things I would be concerned with would be water and algae contamination over time.
If your buying this time of year, I'm sure your gettting winter mix, so thats one issue gone.
I caught the delivery guy and asked him. He said with this super x stuff, it will last forever. I've got a jug of diesel conditioner. I'll read the directions and see how much to put in per gallon and give it a shot of that stuff.
I was going to suggest either Biobor or Prist. It's what we use in Jet A to prevent biological growth in fuel/fuel tanks. Jet A and Diesel/Kerosene are pretty similar
A lot of suppliers for ag/off-road fuels pre-treat for the normal storage conditions so you may want to ask what treatments this fuel already has in it.
Startron prevents algae buildup. It also binds to the algae and water making both sink to the bottom of the tank so you can drain it out, otherwise it is now large enough to get caught in the fuel filter. I would suggest a Racor turbine series fuel water separator between the tank and the pump. It might look expensive at first, but it will allow you to polish your fuel instead of hiring someone to come get the ickies out or buy a polisher. After it is installed, all you do is put the nozzle in the gas cap and let it pump for the duration of the tank capacity. So if it is 100 gallon tank, let it pump 100 gallons and it will clean up your fuel and get the water out. I spent 5 years living on top of a floating 2500 gallon diesel tank, and we left the dock only in the summer. The notion of 1500 or more gallons of $5 a gallon diesel going bad wasn't something I ever had to contend with because I did the aforementioned.
