Power Service Diesel Fuel Supplement
Does anyone use Power Service Diesel Fuel Supplement in their 6.0L? Claims to improve fuel economy by enough to pay for itself. Anyone have experience that validates this claim?
Thanks, |
I have been using it because it was cheap and available and I couldn't find the Stanadyne. You have to double the mixture to get a cetane increase according to the instructions on the label. I have noticed a slight 1 to 1.5 mpg around town. Does it pay for itself? I haven't done the math. With diesel prices shooting up the way they are, it helps.
I ordered the Stanadyne off the net. |
I have a 1999 7.3 and use the fuel supplement also, it comes in a white bottle.I am not sure what the Diesel Kleen(gray bottle) does different.Is there a difference in what they do?
|
I have an '03 6.0 and lose 1 - 1.5 mpg when i use it. I use the gray bottle, the white is anti-gel for cold weather. I have not tried Stanadyne.

I've used the grey bottle. Mine seems to run a bit quieter, fuel mileage might be a little better, but probably not enough to offset the cost. I run 2x recommeded.
|
If you buy it (either the grey or the white) in the big jug instead of the quart size, the cost per fill is really chump change. Whether it helps mileage or not, they both help cold starting, and both now include a "slick diesel" lubricity additive.
And, if you live up north, the white bottle is really a good thing in the winter. |
wwb, you're right. It is much cheaper to buy it by the jug. That's usually how I buy it. I transfer into the small bottles to make it easier to get into the tank.

I've used Power Service in my '07 since it was new. Living in up state NY I use the white bottle year round. I mix it 50% greater than the minimum mixture on the bottle. I get 17 to 18 mpg average - 19 to 20 on a trip at 60 to 65 mph. I like the slick diesel lubricity and added cittane for summer and the idea of not freesing up in the winter.

In a conversation with an engineer from Ford about my power issues, Power Service and Stanadyne were mentioned. He thought the cetane boost would help some with my power issues. He cautioned me that these products do not do as much for gelling since ultra low sulfur as they did on the older fuel blends. He recommended using 50/50 no.1/no.2 blend instead of the additive route for winter protection.

I've been using it in mine shortly after getting my rig and I think it helps. Quieter and around 1 mpg better (after the first couple of tanks). Since mine is the 7.3 and my rubber o-rings weren't designed around ULSD, I use it to help mileage and to lubricate all those pesky o-rings. I use the recommended amount. The bottle says you can't use too much and I'm sure I've built a stockpile of it from the residual left in the tank when I fill it. I buy mine at Wal-Mart for about $16 for a 96oz jug (16oz bottle is around $7). I have a small 16oz bottle that I just pour into and take with me to fill up. You can also get the 16oz bottles at Kragen's (Schuck's/Checker) and Pep Boys (Pep Boys also carries the 96oz jug too). |

I use to use 4 oz, but have started using 8 for the last couple of tanks. I notice better overall mileage and performance with the 2x dose. I wonder what 4x will do? |
If you are running B-5 do you need to run any for lubricity reasons. or will the 5% bio take care of that?

Regarding the Power Service stuff..... both white and grey now have a lubricity additive for ULSD. I'm not certain how effective it is, so I'm still adding a lubricity additive. Both the white and the grey have a cetane booster, but the grey gives you a couple more points than the white. The grey also contains an injector cleaner, while the white contains an anti-gel for low temp use. |

5% bio is an excellent fuel for lubricity purposes. If you live up north, however, you would do well to avoid the bio in the winter, as it gels very easily, and at substatially higher temps than petroleum diesel. Add the Power Service white in the winter.
