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 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 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.

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 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.

“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.”
