Diesel Fuel Additive During Winter Storage

Not always true. Been there and did that and it's not a cheap date (repairing and replacing components and flushing tanks because of algae growing in the fuel over the winter.

While I don't have a diesel pusher, I do have a diesel pickup truck that sits all winter in the garage, next to my truck camper, usually from November to April every year and a couple diesel farm tractors too. I lucked out on the tractors, didn't on the truck.

I got a case of algae (red slime) in the fuel system over the winter 3 winters ago. I didn't know it until I got the truck out and it died in the driveway, I went hmmmm, what's going on, so I did all the usual checks (both fuel tanks were full and I had Power Service anti-gell in both tanks (I have 2 on the truck) so I pulled the fuel filter (my filter sits on a cast aluminum bowl atop the engine.

When I pulled the filter it was a solid mass of red, slimy gook and it stunk. So, I had to remove the fuel bowl (no easy job and clean it plus it ate the lift pump so I had to replace that and I had to pull all the injectors and have them cleaned and benched because the goo was in the injectors too. All in all, I had about a grand in parts with me doing the wrench part. If I had, had a shop do it, I imagine it would have been at least twice that because pulling the injectors on a Powerstroke is a job in itself. Besides the mechanical stuff, I had to drop both fuel tanks, remove the sending units and pickups and have them steam cleaned inside and I replaced both sending units and pickups because they too were loaded with the goo......and all new duel lines too..

Just glad I have the tools and the know how to do it myself...

Moral of the story is this:

Straight diesel with no biocide added, you might get lucky and never have an issue but, if you do, it's going to be a costly one for you.

Biocide is cheap and it don't take a lot. I Power Service Bio-Kleen myself....and a dash of Power Service anti gel too.

That is my story and I'm sticking to it....:B

Additionally, because I have a Powerstroke I also use Archoil Friction / Stiction modifier and their fuel additive (which has biocide in it) as well. I picked up a real world 1 mpg in fuel mileage overall and the motor runs much quieter.

While neither here nor there concerning algae, I figured I'd toss it in too, while I was entering this post.

Have fun.

You have me talked into it. Mine was filled up at the end of October, batteries removed and covered. I'll add some biocide tomorrow.

Cummins has approved Power Service products.

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

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.

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.

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.

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.

I do use the pure peppermint oil, works flawlessly!
