True. But (make that a big BUT) knowing 100% that you do not have any water and that there will be 0% chance of condensation over the winter is too much speculation for me.

Your fuel is at best only as good as your last fuel stop. In other words, who knows! It is sage advise to use a biocide for storage and is not costly per treatment.

If the engine is in storage, and not being used, there is no need to put an anti-gel in the tank.
Diesel fuel does not "rot" like gasoline does, so there is no need for a stabilizer.
When I had a 4X2 one ton dually diesel truck that only rarely got used during the winter, I did not put any additives in the fuel tank. Once the hay barn was full, it was parked and left there all winter.

Agree on Biobor JF as a biocide. Marine stores carry it. In our area, Academy has it the cheapest.

And would also add an anti-gel if storing "summer grade" diesel through the winter. PS brand is found in most Walmarts.

I use Biobor JF in the diesel fuel at every fill. It only takes 1oz of Biobor to treat 80 gallons of fuel. When it is going to sit for a while I will double the Biobor on the last fill.

If it is a diesel, it must be a biocide. Sta-Bil, etc are not biocides and will not keep your diesel fuel safe through the winter. You can find it at a marine store.

I use a biocide when storing a diesel for more than 2-3 months.

I use STA-BIL Marine in our Southwind. Some use regular STA-BIL, some use Seafoam or another stabilizer, and some don't use anything.

I think it's cheap insurance. I pour the Sta-Bil in before I top off the tank so it gets mixed thoroughly. Then run the engine and generator to get it in the fuel lines.

I believe it also works on diesels.
