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.

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

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,

“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 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.

“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.”

“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.

“For years, not only was I opposed to any fuel additive, but was utterly opposed. When anybody asked what additive they should use, I would reply “diesel should be the only thing in your tank.” One day, after trying to battle a fueling issue that left me with white smoke at startup and at high rpm’s, I was desperate and, against what I have always said, picked up a bottle of Tank Cleaner (Clear-Diesel Fuel &
