I bought this stuff at Wally World to add to my fuel for the winter months. Its says its a cetane boost, prevents gelling, cleans injectors, and lubricates pumps and injectors. Anyone tried this stuff or have any comments about it, good or bad? Just trying to find out before I use it.

Ry

I've used it for years in everything from cat, cummins, navistar, and now duramax. No problems. then again, don't know if it did any good. Many of the big rig guys around here use it.
hope that helps

I ran it in my d-max w/o any problems and now in my cummins. I looked up online and it does not contain any alcohol which will kill your pump. The new power services also now includes a lubricant which the old one did not. The additive of a lubricant is on the front of the bottle.

:) I run the stuff constantly and love it in my Duramax!

I use Power Service additive exclusively and have never had a problem. Run #2 year round w/ Power Service in MN and haven't gelled up yet.

I used Stanadyne for most of my first 35-40K miles, now I'm been using PS for the last 10K, truck runs the same and the PS is a lot cheaper and easier to find. Satisfied!

I also use PS in my little JD diesel (1.0 liter engine...woo hoo) and have had no fuel issues in two years.......

Cheap (Walmart), and it seems to work, I don't mind doubling up on mine because the price is so good. No alcohol the key thing.

Power Service is great stuff. I buy one big jug and one small bottle. After you empty the small one you can reuse it by filling it from the big jug, which is cheaper by volume and the lil' guy is easier to poor.

I found some P/S at a local farm/ranch store and it was about a buck and a half cheaper than wallyworld. You might want to shop around.

thanks for the help, this is my first winter with a diesel so im kinda having to get used to adding to the fuel and pluggin in and stuff. just out of curiosity what water temp are most of the people running in cold weather(10's and 20's) getting. i have a cutout billet grill but i have it blocked off behind it. if im out on the road running about 65 water temp is around 200 205 idleing around town its 180 185, which seems too cold???

That's what we always use. It was nice and easy to find on the drive to Michigan.

I also use only P/S. Dealer didn't put anything in my 'free tank?' when bought it new. P/S has been in every tank since. We've had some -10f mornings here and haven't plugged the truck in yet, starts first time every time. And like others here have said, you can always find a WalleyWorld. Get the big jug and a little jug, works out fine.

And now thanks to 'byronlj' post I'll check out the local Farm & Fleet for the even cheaper price. Thanks byron. :ro)

:D We have been using Power Service products in our '03 with no problems since we got it in July. There is volumes of info on additives if you do a search here, but I'd like to direct you to an earlier one that specifically talks about Power Service.

Hope you find this helpful, and that it answers some of your questions.

Been using Power service for over a year now and no problems.. Easy to find at wally world or autozone.

I am currently using Standyne Performance Formula. I am thinking about switching back to the Power Service stuff. About twice as much volume, but half the price.
Been thinking allot about this lately and was going to start a thread.

Can anyone say with any certanty that Stanadyne is any better than Power Service?

Sorry for the hi-jack Ryan.

I like the idea that PS products solubilize water within the fuel. I have recently switched to the Diesel Kleen product because it has no demulsifers and pour point modifiers to take up residence in the package. This allows the additive to be more suited and concentrated for the task of cleaning, lubricating and providing cetane boost which is what I'm personally looking for. You can actually here and feel the difference in the engine. I believe most additives work as advertised and their use would be well justified according to each persons individual needs. Use what you feel is best for your situation and don't be taken in by water handling claims via bottle tests in which the samples have been Super Dosed to magnify the results. They are only designed to handle only small amounts of naturally occuring water within the fuel or from tank condensation.

I use the PS, so far so good.

Good stuff! For me anyway...

I've been using Power Service for over 60k miles and it works great. Temps here in Western NC have been in the low teens and it fires right up in the morning.

I use Power Service in the winter and thier Diesel Kleen in the summer. Truck runs better and quieter and a bit more mpg's.

Didn't GM just issue a letter stating its approval of Stanadyne and 1 other formula. It was not the power service brand.

I have the factory winterfront (grill only) and the only time I get above 185 or so is when running 70-80 on the freeway, on surface roads it stays at or just above the "middle mark" between 160 and 210........

seems like everyone has had good luck so i went ahead and added it to my fill up todays. i have the 26 gallon tank and i added just a tad over 4 ounces. is that sufficient or do i need to be adding more?

i was wondering about the water temp because i noticed when i didnt have my grill blocked it seems like my milage dropped a mile or 2 per gallon. i just didnt know where other peoples water temps were running.

In the summer I switch on and off with PS because its cheap and easy to find. The problem with Power service, and this has been discussed here before and letters from PS were posted, is that it does not emulsify or De-emulsify as it contains no water package. They claim there is no room for a water additive package in their product. I used PS in my tractor last winter and in the spring the filter was very rusted. That was a big clue to me NOT to use PS as a primary additive. I run FPPF but alternate with PS. After switching every other tank with PS and FPPF I found no rust or water in my filters, CAT or OEM after 20k.

Tractor Supply has the best price,

$2.00 gallon jug cheaper thank wally world

I've been using Power Service exclusively since we bought our truck in July, and though I've only changed the fuel filter twice, neither time was there even a hint of rust or water in the filter. And I think they do have water control in the Diesel Supplement.

If you think that you should email their customer service for a straight answer. They are a good company with a good product but not for water control if that's a concearn for you. Their response has been posted here several times in the past. They do have a diesel flush ( Diesel 9-11 ) but I wouldn't want to push all the water in my system through at once if I were in the De-emulsifying camp......Which I'm not. The diesel fuel supplement is a DFA with cetane boost for winter. The only water dispersment product they offer is Diesel 9-11. I ran my first D'max nearly 70,000 miles without a drop of DFA and no problems. However if the fuel that was in my tractor last winter with PS would have been in my truck I would have had big problems. Rust in D'max fuel system = voided warranty.

Been using stanadyne p/f since new, now 21000 miles, but you guys have me thinking. I am afraid to change, just a coward at heart I suppose!

I just bought a new jug of PS and on the back it talks about water control. I do not remember the exact wording, but it led me to believe it was an emulsifier. I will post the exact wording this evening when I get home.

Below is a small part of some correspondence I had directly with a Power Service representative via their web site that seems to address the water question. I would gladly provide their complete answer if anyone is interested.


Our Diesel Fuel Supplement (DFS) contains a deicer that is intended to keep the water in the fuel from falling out. Warm fuel will carry more water than cold fuel. When it gets cold some water can fall out of the fuel, or the water separator can squeeze out this water which can freeze on the filter face and cause the fuel to stop flowing through the filter even though the fuel is still liquid. This is call Fuel Filter Icing and is often mistaken for fuel gelling. The deicer in DFS can also help to solubilize small amounts of water in the fuel system. If too much water is in the fuel tank it can overpower the deicer in the Diesel Fuel Supplement. So, DFS is neither a demulsifier or an emulsifier.

Hey guys try this, 2oz of fppf, 2oz of standine, 2oz primrose, and 4oz of p/f then your worries will be over.

Pay real close attention to the last sentence from Power Service.

IT IS NEITHER A EMULSIFYER OR A DE-EMULSIFYER.

The answear you have only applies to the winter product. ( DFS ) It's very similar to the answears posted here before from power service except they used to include that there is no ro room in their additive package for water treatment and you should use 9-11 for water.

"IT IS NEITHER A EMULSIFYER OR A DE-EMULSIFYER"

Yes, spoken like a true sales person. It has to be one or the other. Its like (hey, it is) water in oil. You have to seperate it (de-emulsify) or disperse homogenioously using polar & nonpolar bonds (like what soap will does to oil in water).

Personally I will stay with the recommendations from GM, at least the first 100K miles.

Here's what it says on the back of a jug of Power Service Diesel Fuel Supplement:

* Disperses water in diesel fuel

Alrighty then... :confused:

So there you have it:cool:

"IT IS NEITHER A EMULSIFYER OR A DE-EMULSIFYER"

Yes, spoken like a true sales person. It has to be one or the other. Its like (hey, it is) water in oil. You have to seperate it (de-emulsify) or disperse homogenioously using polar & nonpolar bonds (like what soap will does to oil in water).

Personally I will stay with the recommendations from GM, at least the first 100K miles.I do use PS but with all due respect I think your incorrect. It does not have to be one or the other. There is no specefic water package in PS except for the small amount in the DS. If your going to follow the general I'd certainly go with PS over stanadyne. Either way you get rust eventually and ones a lot cheaper.
On Edit; A lot of us struggle with which type of DFA to use. Do we risk voiding the warranty by useing a product the general doesn't reccomend ? All I can say is that this is what helped make my mind up. The warranty says rust in the system any place voids the warranty. period. If you seperate the water or never treat it then you have water setting in the bottom of your filters. Eventually you will get rust. I find that a bigger risk of voiding my warranty than running a DFA. Has any one ever heard of a stealer performing a $100 fuel test to see if you have DFA in your system when your injectors die ? Not that I've ever heard of. So for me its standard PS in the summer alternated with a emulsifyer. In the winter I wont use PS after my experience with it and rust. My equipment sets a lot more in the winter includeing my truck.

Buy good FUEL, It's the Business!!!!!!!!!!!!!!!!!

If your referring to off road diesel I never burn that in any of my equipment. I only buy premium fuel....or at least I only pay for premium fuel !

I think buying a quality fuel is the biggest factor in reducing water. If you happen to fill up at a station and get a big gulp of water, I don't believe there is any additive out there to fix it. And anytime you let diesel sit, you will get water in it whether it be from condensation or the small amount of water inherently found in diesel fuel. The water will settle to the bottom, and eventually cause rust. I personally use Power Service additive, it works for me, it may not work for other people. But I have logged approx. 350,000 miles between the 2 diesel trucks I've owned; I've never gelled up, never had filter icing, and never had rust in any fuel filters.

Oh, and by the way, you guys are right about wally world, it's not the cheapest for PS. Tractor Supply (as mentioned above) seems to have the best price.

we use the "quality fuel" and that is all my dad's truck knows we run standyne in all of our fuel and have never had any problems. there was no increase in milage but you could feel the hp increase after we put 2.5 gallon of standyne in the 1000 gal tank at home.

Diesel 66, I would certainly agree that no additive is going to cure a tankfull of bad fuel containing water. I do believe that I can avoid rust in my system, especially my filters by useing a DFA that emulsifys the small amount of water from condensation. Although I do trade off with PS for the cost benefit. Like others I buy it by the gallon at TSC. If I were anti-emulsion and following the general I think I'd certainly want to use a dose of Diesel 9-11 every month just to keep things safe. One bad experience with the tractor was enough to make me very cautious.

man when i started this thread i never saw it going this far...lol. but however, it confused me. so what should i do...continue using my PS and run an emulsifier through the tank about once a month or what? my truck very rarely sits more than a day and i usually buy BP diesel surpreme, most eveyone i know has had good luck with it.

:D RyanU-------use the Power Service exclusively. It works, it's economical, and it's sold nearly everywhere. Use their Diesel Kleen in the warmer months; both at 8oz per 25 gallons. Use it for a couple of months, then come back and tell us how well your truck starts and how much better it runs.

That sounds like a good plan. I'd just reccomend periodicly useing some diesel 9-11 from PS that is readily available at TSC. This is the course of treatment that PS suggests and its what I will likely do in the future now that FPPF has become harder to find for me and more expensive.

sounds good to me. im gonna go to TSC and pickme up a couple jugs on the fuel treatment and a jug of the 911.

I agree with wheatfarmer buy good fuel I try to use one station I've cut all my filters apart and have never seen any rust @ 10,000 miles they look to be about25% used but I still change @ 10,000 miles I've used all the additives and to be honest I can't seem to tell the difference. I guess it does give you peace of mind that I'm doing all I can do to make the fuel system last. I put alot of miles on mine 35,000 miles in the last 7 months and have not iced up it hase been down well below zero a hand full of times this year and it starts fine with out plugging it in.

Just where in our fuel system is the rust going to come from. Not from the plastic tank. The steel lines are stainless or anodized. The only rust reported was in the bottom of some of the new OEM filters. Normanally you need water and air and I don't mean the dissolved oxygen in the fuel. I have seen a hundred rust contaminated hydraulic systems over the years. In every case the rust came from the steel tank and black iron piping on the inlet side of the pump. They didn't have the benefit of a 2 micron filter on the inlet side like our system does. My jug of PS does not have the statement: "IT IS NEITHER A EMULSIFIER OR A DE-EMULSIFIER". As far as GM voiding a warranty, GM doesn't void anything unless your dealer doesn't like you. PS is a good product that has been around a long time. I don't remember anyone posting a problem with it. Later! Frank

I thought I read that rust forms in the fuel rails. ?

Rust also forms in the filters and around the injectors. GM denying warranty service only to those they don't like is probably the funniest thing I've ever read here. ):h Frank's opinion may be a bit jaded as he is running a post-OEM 2 micron filter so its easy to be cavalier when your warranty is history any how. None of us have a air tight system and even if we did cavitation would likely introduce enough oxygen to allow rust. There has been photos posted here before of rust around the injectors. PS is indeed a good product. When I had rust in my tractor filter I was useing the white bottle. I really think the new DS is much better for winter. Once I switch back to PS I will certainly be listening to THEM about the course of treatment to follow includeing diesel 9-11 occasionally. One great thing about Power Service is that you can go to their website, email them and get a straight forward reply in short order. They are the best source of info for anyone with questions about their products.

Hi guys....please be aware that "Diesel 9-1-1" contains alcohols.

Just an F-Y-I, as the newer engines do not like alcohol!

Powerservice is great stuff, I use their diesel fuel supplement in the winter months. In the summer I use their Diesel Kleen it has more cleaning stuff in it and It gives a higher cetane boost for a little more kick

I'm adding Diesel Kleen to my fuel so you guys will be my friends...deal? What's a guy gotta do to get some cetane around here, sheesh!

I use Stanadyne myself and will only use Deisel Kleen if I run out in a pinch. I never run a tank without an additive.

I'm currently running Standyne, but am considering switching back to Power Service stuff because of cost. Still trying to decide if it is a wise choice.... :confused:
