My father purchased a new Ford F350 Super Duty 4×4 back in 2000 with a 7.3L. He is a welder and used the truck for a work truck. So its under load everyday. My father from the very beginning used Power Service in the fuel system. He has absolutely no fuel related issues until around 300,000 miles. Thats when we installed a worn out supply pump. The injectors are the original injectors from 2000. The truck has been sold to a friend of mine. He has continued to use the Power Service fuel additive and has 315000+ miles and still going strong. There is a very small amount of smoke that comes out when you are accelerating out of a corner but if you are not looking for it you will not notice it. I’m a diesel mechanic and I always recommend Power Service to my customer and tell them about my father’s Super Duty. Its awesome stuff.Jason Austin
I just purchased a new 2015 Golf Wagon TDI and on its first fill up I added Power Service and the sales person says what’s that? I said it’s added peace of mind! He then said well we sell Stanadyne Additive. I’m well aware of this but I will stick with Power Service over the other brand !!! Thank you for a product that has proven itself time and time again and I keep a bottle in both my diesels all the time and when filling up. I share the story with other people with a diesel.Manny Stone

Dear sirs, Just a word of appreciation and thanks for your wonderful product Diesel Kleen cetane boost injector cleaner. It has made a remarkable difference in performance and greatly improved fuel mileage. Sincerely, James and Jeannie Holder. Southern Motor Freight.James Holder
We tow. 5th wheel with our truck and on trips with friends are the first one up the big grades using double numbers of cetane. Your product is amazing not only the power increase but the increase in fuel mileage from 17 to 21 mpg. We use the gray bottle during the warm months and we get as low as 16 degrees in the winter mornings when we use the white bottle which always gives us a crisp morning start. When we change the fuel filters the diesel looks like clear gas. No algae growing in this tank. Thanks for a great product. WestWest Fullow
This stuff (911) worked on my bobcat… It started the bobcat quickly after an hr., and a headache! I bought the one that prevents the fuel from gelling in the first place, as well… Chicago weather reaches -35 degrees at times… If it were not for this POWER SERVICE PRODUCT, especially 911, I would have lost over $3,000.00 in snow plowing just for that day… Thanks! Power Service!!! It prevented me from draining my battery and damaging my starter and alternator… This is the truth! For a struggling business, POWER SERVICE DIESEL (911) got me moving, and POWER SERVICE DIESEL gel prevention is keeping me going and going!Louis Vega
“I’m a truck mechanic from Northern Illinois. We use Power Service Products at the shop frequently, especially with the winter we’ve had this year. Just a few weeks ago when we had our last cold snap, I was out running errands and my truck was losing power fast. I managed to limp into to a local truck stop. Fortunately, they had a few bottles left of Diesel 911. Within minutes of fuel treatment, my engine RPM went from 2100 Max to full throttle. I will definitely recommend Power Service Products to all our customers. Thank You for a great product.”Rich Martin

“On the week of 9/26/2011, my Kenworth’s left side fuel tank would not cross over or draw fuel from the left side. I had the cross over line removed and air forced through. That lasted till the next week when the problem returned. We replaced the tank vents and the cross over valve. No luck. Then I was in line to pay for fuel at Petro in Carlisle, PA, and saw Diesel Kleen. I thought why not? I poured the bottle to treat 250 gals in the left tank. Within 30 minutes of driving the tank was working. I add it to the fuel every six weeks. I couldn’t believe it.”Bob Nagel, Jr.
“I was a skeptic about fuel additives. My 2006 6.0 L started to act like it was cutting out under load. I changed all the filters, and it was better but still not right. Started using Diesel Kleen. OMG what a difference! No more cut outs, MPG went from 17.1 to 21.2. Cold starts were always an issue. Not anymore. Starts like it was already warmed up! Starting using it in my 1999 7.3. I just did not know how much power I was missing. Even the wife noticed it! This is now mandatory at every fill up! Had the guy behind the counter at the parts store ask me about it when I bought the big bottle. Told him my story, and said he was going to use it in his 1996 diesel truck. I know he will be a believer!”Darrel Mendoza
“Diesel Kleen is the only additive I use. I average 13 miles to the gallon pulling my 30-ft car hauling trailer. I have a 2500 Duramax and since using Diesel Kleen, I have better fuel mileage, better truck performance, and no fuel injection problems. This product is worth every penny and more! I am so grateful for Diesel Kleen for the boost in my truck and the performance. Thank you, Diesel Kleen!! I am hooked on your product.”Michael Haggerty

“Diesel Kleen provided the closest thing to “instant proof” of effectiveness. At the end of a 3000+ mile trip from SW Florida to Washington state, our 8.3L diesel pusher started shuddering and failed to make power up a modest grade.
I purchased a 32 oz size container of Diesel Kleen and headed for a filling station to get a full load of fuel. Unable to make power on any type of grade I pulled off and added 24 oz to the 50 gallons still in the tank. I then headed back to the campground thinking I was going to have to have the rig towed. Within 5 miles, full power was restored, accelerating up grades a piece of cake. I headed back to the store and purchased enough Diesel Kleen for my return trip.”
