fuel additves which one or any??

[ohiojim]

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.

 

[aeblank]

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.

 

[newbury]

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.

 

[Sawyer Rob]

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!

[Kubota 2007]

I use a lube additive all year round, never had a problem, well worth the extra few dollars per tank full for peace of mind, sure can't hurt.All diesel injection shops recommend adding lube, but warn about using any additive that contains alcohol. Most winter additives do contain alcohol.

 

[number two]

What is wrong with the engine that makes them believe additives would have prevented?

 

[JOHNTHOMAS]

Grew up in the 60s and was not a Motor Honey believer and yes I did add a can one time. I''m generally a non addative in a bottle person. over 170 vehicles and around 20 Kubotas and still not a big believer in addatives. But......wanting to always be open to new ideas that seem to have a degree of logic I'll ponder, meditate and seek advise. Over the past 12 years of Kubota ownership there have been to many supporters of Power Service addative in the white bottle here on TBN soooo I started doing a little bit in each tank full when I remembered it. Did it ever help/hurt? I don't know or didn't until our historical cold winter this past winter in Ky. My RTV1140 froze up at -15 with my wife and grand kids who shouldn't have went out to get groceries as late in the evening as they did. Vehicle wouldn't come up my 15" deep snow drive way so they RTVed down to truck and then was half way back up with a bunch of groceries and the RTV stopped and wouldn't start. I went out the next day and couldn't get it to start. Remembered a had some Power Service in the white bottle. Trugged up to the garage and back with the small bit I had and poured it in the fuel tank and about 30 minutes later I went out and the RTV1140 started, sputtered a bit and then smoothed out. Do I believe in white bottle Power Service? Yes, for severe winter service I do but after my experience I started paying more attention and came to the conclusion that the White bottle is just for cold weather and the silver bottle is for the rest of the year. Am I a diligent user? No but I have a big bottle of silver Power Service and I'll pour some in each tankful when I remember it. Does it help? I don't know but I don't think it hurts and with the other requirement being faith and confidence in my fuel distributor.............I'll just keep using Power Service in the silver bottle when I remember to and when winter comes I'll get a bottle of the White one and keep for another unusual Ky winter,
Still mostly skeptical of super stuff in a bottle but technology has came a long way and many incompetent workers that are supposed to do......................

 

[Turbys_1700]

I use Power Service Diesel Kleen Silver in my tractors. Used it in my Power Strokes for years. Does it help? Don't know for sure but to date have never had an issue with an injector or pump. If it ain't broke don't fix it.

 

[Sawyer Rob]

If it ain't broke don't fix it.

I agree, that's why I don't use any or see the need to use any!

I think this sums it up. One person's experience is not proof. Without knowing the chemistry/engineering (materials & systems involved), we don't really know what is going on. There's lots of magic potions out there, maybe one might do good, might do bad, or might do neither. In all cases the "ain't broke don't fix it" can apply.

Personally, I'm a no-goop guy. That said, I did use some marvel mystery oil on a crappy old car I used to drive. It got rid of the knock that was there previously.

I'm impressed that the anti-gel additives work on an already gelled system. That is good to know!

 

[sixdogs]

The dealer is confused on what an additive would have prevented. The two aren't really related.

Separately, I have used Stanadyne Performance Formula for maybe 20 years and have never had a problem in maybe 3000 hours on eight different tractors. A friend of mine that owns a diesel repair shop suggested it a long time ago and I have used it ever since. Zero problems.

 

[varmint]

Another question that borders on the mystical! Since I have my heating oil guy fill up a 5 gal. jerry can when I need diesel (he tells me that the fuel depot doesn't differentiate between heating oil and diesel, other than red dye) I figure adding the Power Stroke stuff can't hurt, might help, in terms of storing the fuel for who knows how long until I use it. Not ideal, but then again, I have never had a problem. My boiler guy added some stuff to our 250 gal. heating oil tank to kill the crude that was developing in the bottom, and he swears by it. (he doesn't sell anything but service). I would think that moisture and algae could be an issue in a tank subject to condensation.

 

[dodge man]

I will add in my opinion, there are some good reasons to add an additive. Storing fuel for a long time, gas seems worse than diesel though. The second, as someone above mentioned, diesel will grow algae. If algae is growing, there are additives that will kill it. Another is gelling in the winter, although if you buy blended fuel, your probably OK. When it gets really cold, as in near zero, I do add stuff to my truck and tractor for gelling.

Algae will only grow in diesel IF it has water in it, keep the water out!

I store fuel for more than a year without problems, I have some now more than 2 yrs old... (I just came in from raking hay with some old fuel in my tractor)

My neighbor get's one fuel drop a year, and he doesn't have any problems either...
