Fuel Additives?

[MBlanks]

I was just wondering if anyone recommended using fuel additives. I know that some guys believe that you should never run your truck without them. What do y'all think? Are they necessary and if so what additive is the best?

Mark, I don't think it can hurt to use fuel additive as long as you dont use too much. Winter time, you better use additive unless you want your truck/fuel to gell up on ya. Wallyworld sells Power Service I believe, which I havent had any problems using. 30 gallon tank, I've added 16 oz of additive which from a 32 oz bottle that treats 100gallons, 16 would treat 50 gal, so its a little rich, but I've had no problems. I don't run additive in the summer, unless its given to me, but it won't hurt to run some in the summer if your rich. Bill

I think over used the Valvoline Injector Treatment by putting it in three consecutive tankfuls. My injectors performed better, but my injector pump started leaking in the front. After a few tankfuls without any fuel additives, no leak. Just my experience... When I change my fuel filter I fill up the filter with a milder fuel treatment product, (I don't have the name with me right now, if you want it I'll post). Patrick.

I've been using PFFP additive (sold at Fleet Pride stores) regulary for about a year. When the weather got really cold here I bought the anti gel version.

I just guestimate the amount, but I'm probably close to correct judging by how long the battle lasts.

No fuel problems yet, no leaks, just smooth runnin'.

CHris, dont worry about any wars gettin started here

I use whatever I can get ahold of. Stanadyne is my preferred snake oil, but I use the Rotella DFA, and PS Diesel Kleen with good results. I agree about adding something in the winter time, just to be safe, though a little now and then in the summer cant hurt. Do NOT use ATF, it will coke up your injectors faster than anything else. It might have worked way back when, when the average operating pressure was around 3- 4000psi, but not our 8000- 10K psi operating pressure systems. And the VE is the oldest and lowest pressure of the 4 systems in the Super B.

I use Stanadyne Performance blend every once in a wile. Thats all i used to use Cen-Pe-Co Powerflow Clens but i havent used that in a long time.

Personally, I like stanadyne.



Some jacka$$ told me to run ATF through my pump to clean the injectors... .

I like the PS diesel kleen, I bought my truck last fall and made the mistake of buying a tank full of Maverick brand fuel (big mistake!!!)

the truck was running poorly 'til I put half a tank of Chevron gas in. My local parts guy turned me on to the diesel kleen, I noticed a slight improvement in mileage and a big improvement in performance. Diesel Kleen boosts cetane up to 6 numbers, and its pretty inexpensive. Occassionally I run about 1/2 bottle of Seafoam to a full tank. I've had great luck with Seafoam in my gas engines and they claim its good for diesels too, can't really say for sure, but notings gone out yet and last saturday my truck started with out being plugged in in below freezing weather.

that's my 2 cents worth!

JMO, but, at least use something... . SPF, Howes, LE, Amalgamated, what ever.....

Our pumps are solely cooled and lubed by fuel. . and since we're pushing our pumps harder and harder all the time, it could use all the help we can offer... . in my case, no exceptions, short of running outta fuel on the highway I'll wait till I have something to put in before I fill up...

I use SPF for convenience sake since it' more work to get Amalgamated #15.

I used power service for years and years, the white bottle with the antigel from Wally World. When I bought my new truck I was reading all the stuff about Stanadyne so I bought about 6 bottles. Nearest Stanadyne is in Salt Lake City, ~35 miles east. Anyway, I am going back to Power Service. Can't tell any difference in the way the truck runs, but have to bring the stanadyne in the house to warm up because it thickens (gels?), Never had that problem with Power Service at temps to -25 degrees. My Stanadyne hasn't seen Zero yet!! Hard to believe how this stuff got so popular.

Hey Bill,



I have no proof of this but I remember reading somewere that the SPF would do that, when unmixed with diesel. However it apparently never happens when it is in the tank, in solution with fuel...

Now, as I say, I've never tested that theory... it has something to do with the interaction between the two fluids...

I have used it in my tank as low as about 10*F and had no probem myself... .

BushWakr-- I always read the additive threads and read that also. Seems the solvent they use freezes at 0 degrees. The problem is, I can't carry a bottle of it in my toolbox. First time this happened to me, I pulled the bottle out and it was "lumpy".

I was really looking for an increase in fuel mileage since the truck is getting awful mileage. I have been looking for Lowe's but we don't seem to have that out here. Back to Power Service.



Off subject --- This is the third day of snow in Tooleyville and piled up about 18" now on top of the snow we already had. . Wife is now using CTD to get around town.

Making me nervous!!!

Well, I didn't mean to start a thread that was known for being notoriously controversial. I was just looking for some information. I live in TN, and we normally don't get much colder here than the low teens, is it still a good idea to run an anti-gelling fuel additive in these temperatures? Also, what is SPF, is that Stanadyne Performance Formula, or what? Thanks for all of y'alls help, sorry for the recurring thread... .

Hey not to worry Mark... this is a pretty easy going bunch in here... yes SPF is Stanadyne Performance Formula...

Around here, any question is fair game...

Thanks for the invite! I have some SPF that I left in the truck and when I went to use it it was jelled. My question is, can it still be used after it warms and returnes to liquid?
