Stanadyne fuel addative

[JPLB22]

I did many searchs and found very limited info on this product.



I have been using the Stanadyne Performance Formula for about 9,000 miles. I didn't notice any performance gains when first started. I did definately notice when I tried a tank of strait #2 after about 6,000 miles of Stanadyne. The motor just didn't seem as powerful, it felt tired.



My question is, Has anybody had prolonged treatment with the Performance Formula. As in considerably more than 9,000 miles. And is the fact that the motor seemed tired without treatment a sign that it is doing bad things to the motor. The main reason I use a treatment is for cold starts and fuel system lubrication.

I've used Stanadyne products, either Performance Formula or Lubricity Formula for about 20,000 miles, not really much longer than you. I too use it mostly for the lube factor for my I. Pump. I feel it is good insurance. The truck seems to run better with Performance Formula in it, but I haven't done any tests. I will keep using it though.

I have been using the Stanadyne Performance Formula, and have 45,000 miles on the truck. The truck seems to run better when I use it, and get . 5-1 mpg better mileage. I also run it for the lubrication of the fuel pumps.

I have been ordering mine from the DIS website below, and there is some information on the product on the site also.

There are many fuel additives being used, Power Service, Howe's, etc. choose one you like.

The Stanadyne PF is also a cetane booster. That would account for a reduction in power and mileage when you went back to straight #2. I run it mainly for the added lubricity. Been running it for a good 20k mi.

Hey Double 6, I like your acronym for CUMMINS.



This site is so great, you ask a question and answers magicly appear on your screen!!Oo.

I have not used it yet in this truck. If I remember right I used it in the 91 I had. Started using the Amsoil Cetane when I got into it in 95. I use to use the cetane boost in the VW but switched back to the Stanadyne in my VW. I have been keeping track of mpg since I got it. Since I have gone back to the Stanadyne my mpg has increased from 1-2 mpg or more depending on how I drive it. I drive it fairly light footed cause I'm in it to get the mpg. With a 144 mile commute round trip to work I try to get all I can. As soon as I use up what amsoil cetane boost I have left I will go back to Stanadyne. I use to use the Amsoil Diesel Modifier too but I have run out of it now. From I understand Amsoils products(cetane,modifier)are made(blended)by Standayne-they just blend it to Amsoils specs. But I do see a slight increase in mpg with Stanadyne compare to Amsoil cetane boost/modifier. Thats my pennies worth.

Last 9 tanks in the VW NB(most dray of VWs cars)have been 50+,highest 53. ?Not bad for a NB. I get it from www.dieselpage.com too.

I've always used it in diesels... even before I got the Dodge Cummins. If we dont run it in our fire truck we will get alot more smoke. It helps there too.



Stanadynes book... right here in front of me... says the average % improvement in HP=7. 5%, TQ=9. 8%, MPG=9. 6%. That would be hard for me to prove. All I'm looking for is lubricity and lowering pour points in the winter.



By looking at their bar graphs for lubricity, cetane, pour point, and opacity of emissions, they rank the highest of course.



It is interesting to note one brand that does just as good in all the tests (identical numbers although the bar graph looks skewed) is John Deere Winter Formula and Summer Formula. The JD stuff looks as good even by their independent testing company... Southwest Research Institute.

I got 190k miles and use it every 3rd tank.

I've been using the Stanadyne performance formula for a while and like it. I've also used the John Deere winter formula. I think I feel a difference on the seat of the pants meter, no matter which of these I use, as compared to straight #2. Seems to be less smoke too when I use the treatments.

 

[RKrueger]

I've used it in my 99 for about 50K miles, summer, winter, all year long. I add it to my TransferFlow tank as well as the main.

Because it raises the Cetane, I'm probably getting a slight performance boost, but to be honest, I've used it for so long I don't have any way to measure that.

It keeps my tanks clean, free from water and algae, gives me a little better mileage, and most important, lubricates the Bosch fuel pump, which I have had no trouble with whatsoever since day 1.

Cheap insurance IMO.

Robert, are you talking about the Stanadyne Performance Formula removing water and preventing algae? I wasn't aware SPF was able to do that.

 

[RKrueger]

They have some great literature if you have acrobat. Pick from this page:



http://www.stanadyne.com/dsg/dsg_dfa.asp



The brochure says "Helps remove water from fuel", and it does this by using a "Water demulsifier".

It also uses a detergent to keep the tank clean along with an anti-oxidant. The anti-oxidant will also help inhibit algae growth, although if you have it already, you'll have to treat with an actual biocide.
