RE: old diesel fuel in tank

I've always filled up before storage and I think it would be good for you too. The less air in the fuel tank will resist 'breathing' which allows moisture into the tank. Just fill up before you put your 'baby' away. Safe travels, Mark Yeah, I won't make that mistake again. Been worried about it for a month or two, so it's a relief all is well.

RE: old diesel fuel in tank

Baring algae diesel lasts a long time The one that amazed me was a gasser.. Sat for years... Fired up and ran like new after we put a new chassis battery in it. I think what saved me was the long period of time that temperatures don't rise to a level that will support algae growth in our northern latitude. Plus my storage site isn't exposed to a lot of intense Sun. I couldn't even find a mobile fuel cleaning service. Not sure if the same applies with storing gassers... but at least there's an apparent advantage to a cold climate with diesel!

RE: old diesel fuel in tank

Good to hear. We just returned from a 2,200+ mile trip, topped off 2 miles from the house and put it away for the season. Unless something changes it won't come out of the garage for around 7 months. I have zero concern about the diesel going bad. I've owned our Journey since '17 and never even heard of problems with water or algae after storage. But the pandemic set us back a year and the rig ended up sitting for 2 years with only half a tank. I looked into possible issues with the fuel when I fired up the generator and it started surging. That's when I investigated and found out that... oops!, should have put an additive in. Apparently Cummins builds their machines to withstand owner neglect. I'm thankful!

RE: old diesel fuel in tank

Just wanted everyone to know that I took the Journey out yesterday and everything was fine. I wanted to burn off as much of the old fuel as I could so I drove out a rural expressway for an hour and then an hour back, running my AC and generator the whole way. When I got back home I was down to a quarter tank. I filled up with fresh diesel and a 'shock dose' of Biobar. The Lord was good to me. So were the other posters here and I thank you all for taking the time to give me advice. I learned a lot about diesel along the way.

RE: biobar jf

It says "NOT FOR USE IN ON-ROAD VEHICLES" because it is not a certified fuel. Other than that, the remaining issue is if you have contamination, it may clog the fuel filters. Just be ready. Matt - a ship's engineer that worked in Detroit Thanks, Matt. Already have replacement filters. Am I correct that there are two? Does the generator have a dedicated fuel filter? 2011 Winnebago Journey 40l. Also beginning to wonder about my DEF. That's two years old, too, although I think my tank is pretty much full.

RE: biobar jf

Yup, add the biocide NOW. If you have a long filler tube, follow with 4-5 gallons of diesel to make sure the biocide gets down into the tank. The biocide would do you any good if it is stuck in the filler neck or hose to the tank. Good advice. Maybe I'll mix the shock dose of biocide into a couple gallons of diesel, and then pour it in. Hey, Wolfe, do you have any idea why the bottle of biobar includes the disclaimer against using it in 'on road vehicles'?

RE: biobar jf

I have been using BIOBOR JF for 8 years in my Cummins ISC 8.3 without any problems. Like it says, 1oz for every 80gal fillup has prevented any microbe growth problems and my coach sets for months at a time in hot, humid weather. Thanks for your reply. I've had a motorhome sitting for 2 years with a half-tank of fuel and no treatment. Going to take it out in early October. When would you suggest adding the Biobar... and how do you make sense of the label cautions? Add the BIOBOR JF NOW and use the shock treatment amount, then take the coach and fill the tank with fresh fuel. This will get things well mixed. Living in north it's unlikely you have much microbe growth, but this is cheap insurance. As to the labels, I don't have an answer I never saw that. Probably C Y A lawyer speak. That was my exact plan. It will have to sit until October, though. Should I let the shock sit in the tank till then? I was planning on treating the new fuel as well, as it will be mixing with the old fuel, and diluting the 'shock' effect. Make sense to you?

biobar jf

Bought a container of Biobar JF to use in my Winnebago motorhome. It has a Cummins diesel in it. In reading the instructions it lists many types of engines to use this in, such as diesel boats and stand-by generators. It does not list RV's. In fact, in bold print it says, "NOT FOR USE IN ON-ROAD VEHICLES". Did I buy the wrong product?

RE: old diesel fuel in tank

Yes, fuel polishing (common on diesel boats because of the same storage issue) is an alternative. That will remove water, microbes, dirt etc. That is what the fuel filters and water separator is for. You have the systems already installed on the vehicle. I think and pray you're right pastor. Can't get out until early October, but hope my filters do the job they were intended for. Taking spares just in case.

Yes, fuel polishing (common on diesel boats because of the same storage issue) is an alternative. That will remove water, microbes, dirt etc. It will not "cure" diesel that has "turned". Smell fresh diesel, then smell from your fuel fill. We are not talking about a subtle difference! Yes, we FEEL you will be fine. But would sure hate for our long-distance opinion to lead you into an expensive repair. Got a chance to sniff my tank today, and it smelled like fuel to me. I didn't pick up any hints of algae or decay.

You have the systems already installed on the vehicle. Not sure what a mobile fuel polishing service would cost, but I'd have to compare that to the cost and trouble of replacing my fuel filters a couple times. Might it not be easier and cheaper to have the fuel polishing done (if I can locate a mobile service)?

I have a Love's across the street from my campground and they don't do it, nor did they know anyone who does.

RE: old diesel fuel in tank

I live in Florida with our heat and humidity. I left my diesel pickup sit for a bit over 2 years. When I went to start it, no problem. I drove it to the nearest station, topped off the tank and I was good to go. Never had any issues. Now if you are still concerned, one option is to get a fuel polisher to come over and clear your fuel. Since you are in Michigan, there will probably be some fuel polishing companies on the lake that can come over and take care of it. Here are some in Michigan from Google. Good Luck Hey, thank you, Joe, that's a really helpful post. I'm going to look into this.

RE: old diesel fuel in tank

As it has been said, if it smells ok, just top it off and then drive it off, or at least as much as you can. I would highly advise having spare filters. I'm not sure I could tell you what good diesel smells like. Maybe I'll have someone more knowledgeable take a sniff. But you think I should get some fresh diesel in it right away?

RE: old diesel fuel in tank

Actually, your NOSE is a very good guide to the state of the fuel. If it still smells like diesel, you are good to go. If it has "turned" have it drained-- someone may be able to use in an oil-based furnace. If turned, certainly not worth doing damage to an expensive injection system. Tell us what your nose says. Hard to know what to do when others are sayin 'just drive it'!

RE: old diesel fuel in tank

If you have to hit the fuel with a biocide, be very ready to replace both fuel filters and learn how to bleed a dry fuel system. Matt Well, I guess I'll have to be prepared to pay someone to do the work that needs to be done. Obviously I'm a novice with diesel engines.

RE: old diesel fuel in tank

Algae, I have read, only grows when water is in the tank. It grows at the water/fuel interface. No water in tank, no need for biocide. Water in tank, the tank should be drained and cleaned, then filled with fuel, and all fuel filters replaced. Correct. But (OK large BUT) the original post said the tank was stored HALF FULL for two years. Very likely there has been enough condensation to provide the water necessary for microbe growth. Storing with a full tank reduces condensation. On the upside being in Michigan the rig is in storage during the cold months of November-April, which should help inhibit growth. I've had the rig since '17 and in all honesty have never added a biocide and never had an issue. The difference this time is COVID kept us from traveling in '20 which ended up doubling the time it sat untreated.

RE: old diesel fuel in tank

Carry a spare fuel filter. Already have that on order and will carry it with me just in case. Still wondering what the advice is on when to top off the tank. Should I do it ASAP before trying to use up the old 40 gallons? Either way, prior to storage for Winter I plan on having the fuel filter replaced.
schmitts711 08/21/21 05:26pm Class A Motorhomes
RE: old diesel fuel in tank

Biocide is something like Biobar JF. I was looking for biocides on Amazon and saw this. Sounded like what I wanted. I was going to add a shock dose (1 ounce for 40 gallons), let it sit for a week or so, then run the rig and generator. If everything is okay, I'd try to do a trip where I can burn off the old gas. Should I try to burn off most of the half tank before topping off?
