fuel additves which one or any??

ok 2007 B7800 dealer thinks my engine is bad from NOT USING additives.. so if I,m going to add stuff to the fuel whats best, I have a RTV and this 7800.

Outside of using IPA to absorb moisture. The rest are witchcraft, sorcery and potions. If diesel fuel gells it's because it's the wrong fuel for that climate.

I use power service in all my diesel fuel year round. It prevents bacterial growth as well as helps to increase the cetane rating. Never had a problem with fuel! In my book it is cheap insurance.

I have never used anything in my diesel and never had any problems. I just recently changed my fuel filters for first time at about 400 hours for my Kubota RTV and my Kubota B26 TLB. With anything newer than late 1980s/ early 1990 model, you shouldn't need any additives other than possibly some anti-gel additive if you have weather below 20F for extended periods and you plan to use your tractor. Using it year round is a waste of time and money because it isn't needed. If you store your fuel properly and don't get a bunch of water in it, biocide isn't needed. My tank has been in constant use for 5 years and there is no water in it. The tank is stored inside an enclosed shed with good ventilation.
Basically you can use whatever makes you feel good because folks that load up with all kinds of additives and report no problems are getting no more than I do with no additives.

NOTE: I don't have any use for my machines if it is below 20F so they set in the storage shed or garage although my BIL did use his tractor last year when it was 15F without any problems with gelling and no anti-gel is used and we have summer blend fuel I assume since we topped off our tanks in the spring/summer.

I would talk to a different dealer if that is what they claim is wrong with your engine. A newer tractor engine like yours should be designed to run ultra low sulfur diesel without any problems. Are you talking to a salesman or mechanic. If mechanic, I would take my repairs to another place.

I agree, additives really shouldn't be required. I have used them in the past but mainly to prevent gelling, but as said above, if the fuel is blended correctly, it shouldn't gell either.

Ask them where in the manual it states the requirement of said additives.
I haven't used additives in the last year, and my dad hasn't for the last 15+ years.
I FIFO my fuel and only keep a few months supply. I *try* to run out when it starts getting cold so I can get the winter blend(s).
No issues for this boy.

Lubricity Additive Study Results - Diesel Place : Chevrolet and GMC Diesel Truck Forums

A key statement in the dieselplace.com study: "The Research firm obtained a quantity of untreated ULSD fuel from a supplier. This fuel was basic ULSD fuel intended for use in diesel engines. However, this sample was acquired PRIOR to any attempt to additize the fuel for the purpose of replacing lost lubricity. In other words, it was a worst case scenario, very dry diesel fuel that would likely cause damage to any fuel delivery system." It is my understanding that the fuel we buy already has a lubricity additive. This study really doesn't tell us if an additional additive is of any benefit to fuel that has already had a lubricity additive added. The question for me is, can I be 100% sure a lubricity additive has been put in the fuel prior to me buying it.

There's a 2003 presentation by Bosch http://www.arb.ca.gov/fuels/gasoline/meeting/2003/022003bosch.pdf which describes the lubricity problem.

There have been MANY failed Bosch injectors.

Do you have a Bosch injector?

Neither of my Kubotas have one and neither do my Fords ('88 and 2002 7.3's) however my '09 VW JSW TDI does and I make SURE I add lubricity to it's fuel. As far as I could tell from all my readings too much lubricity isn't a problem.

I don't use any, nor do my farmer neighbors or my relatives, all of which own numerous diesels. NONE of us are having problems...and combined we have several Kubota's along with numerous other brands...

Buy good fuel, store it properly and you don't need any additives...

I agree, if you have gelling problems in cold weather, you are using the WRONG fuel!
