Diesel winter storage

Fill the fuel tank all the way up and park it.

Hi all,
Should I use a diesel fuel additive when I put my motorhome up for the winter? Not sure if I should use an anti fugal treatment or something. Also do I need to do anything special to the generator before I put it away? Thanks.

never hurts to put in a algae/water additive for storage, if u do run it long enough it goes through the system
Other than the obvious MH chit regarding water and batterys
don't need anything special for generator
just don't be one of those people that thinks you need to start either of them every 2 weeks or month. leave them sit till your ready to roll in the spring

I use diesel additive products from http://powerservice.com/ and recommend them highly. Most are available at Walmart.

I also recommend that you use a fuel stabilizer while you make your last fuel top off before storing (important the tank be full). Then run the coach and the generator so all lines are treated. Park it and do not start either again until you are ready to travel again.

With a lot of stations now having Bio that has a short storage time.
Add Diesel Sta-Bile and some Biocide. Walmart carrys both.

If filling up now (a good idea to always keep the tank full to minimize condensation) you have a tank of #2 diesel.

Since you are way up north, you need to add an anti-gel. Walmart, etc carry PS brand. Be sure to drive far enough after adding it that it gets circulated through out the system including generator.

I would also add a BIOCIDE if storing for more than a few months. Biobor JF is a common brand and available at most marine stores, etc.

As others have said. Fill it up add an additive and park it. Think about how many farmers and others leave 'em sit all winter and just start them up in the spring.

Farmers also put coffee can on the exhaust and disconnect the batteries.

That is the first for me with the coffee can and it makes sense to ensure condensation doesn't go back into any of the cylinders, at least the ones with the exhaust valves open. Being from cold country I've learned my lesson and add both an anti gel and biocide and let it sit. Additionally with all the cracked manifolds on the isc no need to stress it with large temperature changes with periodic startups in the middle of winter. It's the fuel which has caused most if not all of the issues I've had in the spring and since I've used the additives I have had no spring issues.

although iam certainly not against fuel additives one has to realize if your tanks clean and the fuel is clean fuel additives will have no bearing on any spring start issues
the can that was alluded to was regarding farm tractors that used to have vertical exhaust stacks with no cover. nothing to do with a horizontal tail pipe
