I recently purchased a bottle of diesel Kleen and was amazed how it increase power and quietening down injector chatter this was first time using your product but will now be a regular buyer.

Diesel Kleen is 100 percent better than anything on market.

Wanted to send along some pictures of the port forward fuel tank on a 2002 Fleming hull# 55-126 we worked on recently. There was a fuel blockage from a foreign object that either fell in or was pumped into the tank. After removing the foreign material from the valve, we took some great pictures of the inside of the 14-year-old fuel tanks that have been maintained with your products! This is only the third time that I had to get inside of a 55 Fleming fuel tank. Two of the boats have been maintained using Power Service products and looked excellent inside. The third boat did not use your products and it had a tremendous amount of sludge and build up on the walls and floor of the tank. We will do a mass emailing to our Fleming owners showing these pictures and how well your fuel products work at keeping their tanks clean.

I have used Diesel Kleen in my work van since day one. I’ve had zero fuel related issues and my engine starts easily every morning. I average 19 mpg with mixed driving in an 8,000 lb work van…not too shabby. I’m all about preventative maintenance, Diesel Kleen seems like cheap insurance.

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.

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.

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.

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. West

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!

“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.”

“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.”
