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!!!!!!!!!!!!!!!

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!

My 2003 6.0 powerstroke was starting hard and shaked at idle. The engine was also very noisy. I went out and bought some grey bottle diesel kleen poured it in and within the next day idle smoothed out it was less noisy and smoke was way less. This stuff works great.

Never “believe” in such thing as fuel additive, BUT there always first time for everything.

Found PS Diesel Kleen + Cetane in one of the hardware store here, put it in my fuel tank before filling up.

Notice the different INSTANTLY, it is not about fuel consumption. Because my engine only 2.5 L TDCI, so it is always has good one.

The noticeable thing is how the engine run in acceleration, my car weights 2.6 ton with 2.5 L turbo common rail, manual transmission, previously the engine “easily” give up below rev-band (1800 rpm), have to downshift.

After using PS Diesel Kleen + Cetane Boost, i have wider rev-band (a lot below 1800), no need for much downshifting, good in traffic jam. Engine also sound smoother.

Great product, will use this till i cant find more (i only can find one hardware store which sell PS products and it is only PS Diesel Kleen+Cetane Boost). Don’t know how many stock they have, i hope it is a lot.

Thanks for the great product .. 🙂

I do use Power Service Products mainly in the winter, so we don’t gel up. Thank you again.
