Diesel Tank fill level when stored over winter

[Lobo]

Question regarding how full should a diesel tank be during long term storage. Still want to start engine once a month. Near empty, 1/2 full, full? Additives or no additives.

I have always heard to keep it full during storage. Less chance of condensation inside of the tank.

Conventional wisdom and my practice is to have a full tank when the rig is parked for any length of time beyond a few days. A full tank prevents condensation and it’s associated ills. I also put a few ounces of bioguard in the tank.

It appears great minds think alike @skychs.

As others have said, we store with a full tank of fuel. And, we run the engine and generator for 30 minutes each on a monthly basis.

Always, always store with a full tank, even if the tank only requires 15 gallons or so. My Rv is my safe shelter in case of a disaster such as an earthquake or serious storm. A full tank gives me lots of generator run time if ever necessary. And, I agree with the possible condensation problem.

I add a biocide various times throughout the year for added protection to ensure no algae etc. grows.
