I wanted to get feed back about these products, the formulation seems very similar. Redline and PowerService are both available at my local Tractor supply, but I would need to order the Stanadyne. Wanted to get some real world feed back from users out there.:ro)

Well I just started my rig on Stanadyne. I had an issue with black smoke going down the freeway at cruzing speed.

Took it to the dealer and they said we don't know? The computer didn't spit out any codes so we don't know.
So from reading around here and finding out that Stanadyne is the prefered additive I found a local dealer adn got some. In just a couple of gallons after adding Stanadyne Lubricity formula, no more smoke and it seams to purr a bit beter.
So people are saying there is something wrong with the truck if you need an additve to make it run better. For gasoline OK but Diesel I'm not to sure about that. Reading all the issues with diesel in general like water tar balls and just dirty diesel. I bet the diesel GM engineers use is top quality stuff.
So for a while I will use a lil bit of Stanadyne every tank full.

Stanadyne is the most popular and is also backed by GM.
I had to order some as well, but one case will last me over a year so its no biggie.

I used Redline for 9 tanks when I first got my truck as it was available at a local parts store, I am now running Standyne. My experience is that Standyne reduces engine noise (fuel knock?) more than Redline. MPG gains with both Standyne and Redline are negligible maybe .5MPG’s hand calculated but a MPG improvement that small can be attributed to many other factors.

I personally don’t run additives for the MPG gain, but more for the fuel quality (i.e. cetane) and lubricity improvement, and as Standyne builds diesel injection pumps, injectors and several other diesel fuel system related components I think they know a thing or two about diesel lubricity than most other companies. Redline is certainly much easier to find than Standyne as it’s available at most auto parts stores, and I think it’s better than running just straight #2 diesel, but for my $40k investment GM approves Standyne and more importantly so do quite a few of the knowledgeable members of this forum so Standyne gets my nod.

Love the stuff:D ; hate the smell:eek:! (There's a pretty funny story over on "Off Topic" about Stanadyne stink; it may save you from the wrath of Mama). All my problems have disappeared after using this stuff - smoke's gone, noise is down, mileage is up a lot (3 mph in all conditions). The others may be just as good, but I wanted to use the one GM approves. Like Briano says it's a small investment. Mine delivered came out to $60.89 including shipping for enough Performance Formula to treat 720 gallons of fuel or $.0845 per gallon. Got mine from DIS http://www.dieselpage.com/additive.htm . Anyway, that's my opinion and opinions are like belly buttons: everybody's got one:p . Rowdy

my truck gelled up using power service. it said 1 qt. would treat a 100 gal of fuel so i put in a half a qt. i will never use their product again its just like adding water.:mad: just my 2 cents worth

I was talking to the guy at COOP today about filling our 1000 gallon tank with clear and he said that when they fill their main tank they put power service additive in it rather than mix #1 in. He said they do that because the truckers complain about lack of power from the #1. So what they sell at the pump is the same as what he would deliver us. We've been filling at their pump with no problems when it gets cold so I suppose it must be ok. Cheaper than having #1 mixed in too. He said the amount he puts in is supposed to make it equivalent to a 50/50 mix of #1/#2. The other place I talked to said they didn't run an additive, just mixed 25% #1 in. But it would add 10 cents a gallon.

i just finished using a case of stanadyne and am now going to use a case of FPPF ( not sure about spelling ) and see if theres any difference. im only on my first tank of it so who knows but i had good experience with stanadyne, better than the others IMO

Once you start using Fuel Power (FP60) by www.lubecontrol.com you will never use those mentioned above again. Start using something that will truly help your engine.

does anyone have any information on this produce other than the website ??

I've run Power Service from day one. 7,500 miles now. I run .64oz/gal. It does not appear to improve mileage. It does quiet the motor down a little. No gel problems to date. I'm sure Stanadyne is better but I've been too lazy to hunt it down on the internet to purchase it. Power Service is available from many sources around me locally.
