Low price for diesel

Diesel prices around me went below 3 bucks a gallon. If I put fuel in my auxiliary tank how soon should I use it before it goes stale???

    Regardless of what others have gotten away with, Biocide is cheap insurance that will keep you from repairs that will run into the many thousands. Algae can start forming in a matter of 4 to 6 months and you wont know until it's way too late.
  • Put some biocide in the diesel. The new ULSD content will get algae etc a lot faster than the the old fuel with sulfur in it.
  • I can't verify it, but heard stories of dozers and other equipment sitting for years. They put in a battery, gave it a shot of ether and had it fire up and run OK. So letting it sit for a year should be no problem. I would be more concerned if it was biodiesel.
  • Ive been told you can store it for a year. When I return in April the truck is stored so the tank is full and the fuel is now 8 months old. I just started it and took it in for servicing and it is fine.
  • Diesel lasts a long time, especially if the tank is clean and free of water that grows algae. My motorhome has a 150 gallon tank that sits for nearly a year between fills with no issues. Diesel doesn't really go bad like gasoline does.

    Diesel prices here in the Minneapolis area are crazy right now. There are three stations locally right around $3.19 and the price then jumps to $3.49 or more. It is simply highway robbery for gasoline to be $2.29 and diesel $3.49 at the same station. In Texas one can buy diesel for $2.29 which is the price of gasoline here.
