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…

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!!!!!!!!!!!!!!!
YOU ROCK

I was introduced to Power Service products after repeated injector failures in my 2006 6.0 injector problem after injector problem for the first 75,000 miles. After the last injector I decided to add Power Service to each tank of fuel, I notice a quieter engine shortly there after, but most impressively I never had another injector failure or fuel system problem again, I sold It with 325,000 miles in it.

I purchased the machine second hand and noticed that it had a misfire, after contacting local mechanic he said we needed a fuel injector. I stopped by my local diesel provider and pick up Diesel Kleen Cetane Boost. I ran about 3 tanks of the Diesel Kleen through the machine and the misfire is gone. I’ve been running the Diesel Kleen in all my machines for about 7 years.

I bought the truck in Minnesota in February at an auction from the military. The vehicles sit a lot and it was cold and hard to start. It ran ok but didn’t seem to have good power. I stopped at the first truck stop to fuel up and find some additives for the fuel. Luckily I bought Diesel Kleen. With in a quarter tank it was running smoother and had better power. I drove it all the way home to Washington state. I now use it in my Ford 7.3 and an older diesel army truck. They all run great. Thanks for a great product!
