Diesel Fuel Additive During Winter Storage

I put a bottle of Power Service injector cleaner in about every other tankful and one into the last tank. You need to drive it for a while to get the stuff into the injectors. On that last fillup I also use Power Service anti-gel. Probably not needed on Cape Cod but it's cheap insurance. Wal*Mart carries this. They also have a biocide, but if you keep the tank full you shouldn't need it.

In 40+ years of having diesel vehicles only once have I gotten "bad diesel" and I buy from whoever has the cheapest price. Unfortunately my DP has sat for the last six months and other than parking with the tank full I do not worry about it. I also do not crank it up until the day before I plan on leaving in 14 days.

don,t forget the peppermint oil and fresh cab to keep the mice out. your fuel will be just fine.

Get the biocide, even with a full tank, you need it, it's cheap insurance.

I do use the pure peppermint oil, works flawlessly!

Algae is a warm/hot weather problem - you're doing winter storage. For peace of mind dump a bottle of Power Service Bio Kleen into the tank. Order from Amazon.

Since you're putting additives in the tank get a bottle of Power Service Diesel Fuel Supplement also. It will help with any condensation in the tank. Amazon

Be sure to run both the engine and the generator so both products are in both fuel lines and engines.

Before adding any additive to any fuel, do a google search for the Material Safety Data Sheet (MSDS) for the stuff, to find out what is in it.
Many of them are Acetone, light petroleum distillate (diesel fuel), and Isopropyl alcohol (IPA).
Then do a search for "home brew diesel fuel additive". You can make your own for $5 per gallon or less!

I have read that algae can/will only grow at the water/fuel interface. If you have no water in your fuel tank, no algae can grow. I do not know if that is true or not, but it makes sense.

If you filled before weather turned really cold, you need to add an ANTI-GEL. PS brand is sold in most Walmarts. That keeps #2 diesel from gelling. Fuel you buy right now where you live should already be "winter blend" and probably does not require an anti-gel.

Additionally, as others have suggested, use a BIOCIDE. Biobor JF is a common brand, and is even sold in Academy stores in our area.

Do not confuse either of these with injector cleaner or fuel stabilizer. I am not recommending against them, but many do not do the same things as mentioned above.

Thanks all, I did fill up with "winter blend" before storage, and with the cold temps it sounds to me like the algae issue is a non-issue. Cummins says no additives needed, and they built this engine, so going to stick with that.

Cummins's advice is just fine if you are driving it. It does not address storage.
