About Us

I own & operate a Rock & Roll Entertainment Company that works the 6-State Region year-around. On New Year’s Eve [12/32107] this year we performed 3 shows for the Make-A-Wish Foundation in Aberdeen, South Dakota. I was fully aware of the local weather forecast “up-there” warning of the likelihood of -18 Fahrenheit temps overnight. We were running one 55 gallon tank which had 15 gallons of “Zero Flow” #2 Premium Diesel, and 37 Gallons of #1 Premium Diesel, along with 12oz of Regular Power Service. I have ran Power Service for decades, and it has never let us down … until the next morning. Because the new forecast was upgraded to have even lower temps [under -30 Fahrenheit] I opted to set the controls on the truck for 1300 R.P.M and let the truck run from 4:00am until 8:30am to insure that we would not have to fight starting the truck in those kind of temps. [the actual temp had dipped to a real -32 without wind-chill factor] The truck ran perfectly until we hit 60mph 3 miles south of Aberdeen when the engine lost power and began “chugging”. I have operated diesels for over 3 decades, and I knew instantly that it was gelling and that it was my fault for not using a stronger mix of #1, and perhaps a few more ounces of Power Service. In our truck, I have always carried a bottle of Power Service “911” in the emergency kit. I was able to keep the truck running @467 R.P.M. by manipulating the throttle; my partner meanwhile took our funnel and the “911” … poured it into the remaining 29 gallons of fuel; within less than 3 minutes … our engine was running perfectly without another “hitch”. We had carried that “911” for over 3 years, have never needed it … until then. I was so impressed that I vowed to tell all of my “Diesel Buddies” and want EVERYONE ELSE to know that Power Service “911” is “The Real Deal”. I will never travel without it after this episode!! Power Service Products are irreplaceable. John McCormick

My understanding of “Pixie Dust” was that it was a fictional substance. Its’ not…it exists in Diesel 911!!! My 2017 Silverado Duramax was sitting in sub-zero temps for three days, -5F ambient temp and -30F with wind chill. Truck was not started during that timeframe and sat in driveway. When I finally started at -5F it only ran for seconds and stalled. Fuel was not previously treated. I put in Diesel 911, and like magic after just 15 to 30 seconds in the fuel tank the truck started and KEPT running!!! Amazing how a bottle of this stuff could de-gell 30 gallons of fuel in seconds. Saved my bacon!!! Thank you…

I’ve been a Power Service Diesel user since 2009, I have used it regularly in 2 Ford and 2 Chevy diesel trucks and never had an issue with fuel gelling or clogged filters or injectors. I’ve also had great results in using it in my Cummins equipped motor home, that also has an Onan generator and Aquahot diesel powered water heater. This past week it got down to -3 degrees F, and all three systems continued to run without any issues what so ever. I’m sold on Power Service Diesel products and continue to recommend them to others when I can.

Ok, my old truck to be its age only has 225k on it. Well recently I been having hard start ups. And rough idle. I tried several diesel additives. No results at ALL. This is where I was totally shocked. Bought a bottle of diesel kleen. Used it. Within 20 miles, I could tell a noticeable difference. After two tanks later using diesel kleen. Problem is totally gone. And has been running great over 6 months after using this product. It really works…

I’ve used several additives. I just recently bought this diesel kleen and all I can say is WoW like a whole new engine. highly recommended.

Have been using power service since new. Now at 750K miles later,have never had an injector problem or pump issue. Still all original and never been out of the car. Great product for today’s fuel.

Was browsing through the Autozone ‘additives’ section and decided to buy a bottle of Diesel Kleen on a whim. I noticed a difference in the engine within the first 6 miles I drove away from the gas station. Engine seemed to pick up faster, run smoother, and idle smoother. So glad I didn’t throw the bottle away after I dumped this stuff in my tank, had to see just what I had thrown in! I’m gonna be a Diesel Kleen customer for life!

I have been using Power Service Diesel Kleen since I purchased my vehicle. I swear by it and will recommend it to anyone! I have put 270,000 miles on my Jetta since I purchased it and have never had any issues!

Just wanted to let you know I operate A Hot Shot business and travel from my home in Florida to Alaska. This route takes me through some of the roughest and coldest climates in North America along some of the most deserted roads like the Alaskan Hwy. I always use Power Service and it has never left me stranded even with temperatures at – 30F. Keep up the good work and i’ll keep using Power Service.

I run over the road, so mileage matters.
Used your products through the winter, and saved me many freeze up’s. But had been noticing decreasing fuel economy. So I added a container in one thank, {300gal) total. I just saved 80 gal of fuel on my 4000 mile trip!!!!!!!!!!!!!!!
