What should I do to prevent Diesel Fuel problems?

This is my first DP. I have read about algae problems but don't know why they occur.
What precautions should I follow to keep things running smoothly?
Is it important to always store the rig with a full fuel tank?
How about additives.
I line in CA. now but moving to Flagstaff in a couple of year, so there will be colder temps coming.

This is all new to me,

Thanks,

Dan

Now this just confuses me even more. Most of these additives are for winterization, which I take to mean improving mpg at low Temps.

When you read info from additive manufactures, they make it sound like diesel fuel is crap until you add their product.

Is everyone on this forum using a additive?

Nope, only stabilizer on a full tank for winter storage to prevent gelling.

i am in so cal. last winter/spring i had a problem on starting/keeping running due to water in the fuel. when i changed the fuel filter i noticed a lot of black flakes (size of a sesame seed) in the filter. i was not sure if it's algae. but in the past summer and up to now, my engine has been running smooth. in order to keep the fuel in stable condition, i added this to the tank http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
it's suppose to be good. time will tell.

I suppose you should check with your engine manufacturer first for restrictions. I have a bunch of different diesels and do not use any additives except for one and that is a Kubota and the dealer strongly recommends an additive. The rest of my diesels are either John Deere or Mercedes Benz or Cummins. I doubt if an additive will do much damage as long as it is a reliable brand, but I have never seen any reliable studies that supported their use. I strongly recommend just adhering to a basic preventive maintenance program.
1. Change all the fuel filters often. And use a quality filter. Don't cut any corners here.
2. Keep the fuel tanks topped off when in storage.
3. Buy fuel from stations or distributers that have a high turnover.
4. Top off the tanks of stored equipment with winterized fuel if you are in a cold climate.

I was involved in an algae in fuel study a few years back, and I can tell you that the conditions that bring it on are what I would call abuse and neglect. It just does not pop up out of nowhere. Again, the above plan will pretty much reduce any risk. Algae gets its start with high outside temps, low tank levels and time.

As far as bio-diesel is concerned, I see a lot of negative comments on this stuff, but I have been using it in my equipment for several years and have had no problems with the bio content. I have had blown injectors, leaking pumps and blown high pressure lines, but I could not honestly attribute those problems to the fuel blend. I have a couple of DEF engines and will not use an additive in one unless the manufacturer has recommends it, and they do not.

Keep it simple.

As your coach is new, your engine is designed for the newer ULSD fuels. So what you add to your tank would be less important then what a coach with an engine designed to run pre ULSD. All of the products recommended are good. I find the cost of the Biobor JF to be reasonable, and use it in every tank.

I will add to the other great input about keeping the tanks topped, high volume stations, regular schedule filter changes with good quality filters. One other are of higher need of preventative tank supplements, are areas of high humidity. High humidity coupled with higher temps, like down in the South East, provide a higher risk of problems.

For those with engines designed for pre ULSD, I recommend fuel additives that also provide lubrication. I use Optilube, they have different products to choose from. As mentioned, in colder travel areas, the winter protection for gelling is important. Either by tank full of fuel with the winter additives, or by adding winter additives protection. Optilube does have winter protection products too.

Best to you with your new ride, enjoy, and travel safe,
Smitty

When storing, this is what you need, it's a biocide. Many of the products listed in this thread are not biocides and will not protect against algae when in storage.

Dan.....Congrats on your new coach. If it were me, I wouldn't do anything until you move to Flagstaff, except keep your tank full. The California weather is so moderate that you really won't have issues. I've had a DP since 2005 and never had a problem. I do use an additive, but for other reasons (lubricity).

Once in Flagstaff they will be offering winter and summer fuel. You might start using a biocide then.

Since we live in California, always having a full fuel tank can be important in case there's an earthquake.

To Dan, this is the best advice you'll ever hear.
Algae is not algae What is commonly called algae is actually formed when the fuel system is not properly maintained. Follow vraines advice and you'll avoid fuel problems, plus save money.

Thanks for all of the great advice. Now all of this makes a lot more sense.

I will rest a lot easier now.
