I use the silver bottle in summer and white bottle in winter for 10+ years! Will not put diesel nozzle in tank, till I add Power Service diesel clean to tank first. Never an issue from injectors! I encourage anyone with a diesel motor to actively use this product. I am a true believer in its performance and fuel mileage!

My mechanic recommended me this years ago when I had my first diesel truck. Never stopped using In any of my trucks. Superior performance improvement and smooth starting. While my friends are changing injectors, My truck Is in service and doing work!

Happy, happy. I bought a nice used Vermeer CTX100 mini skid steer with a Kohler KDI1903TCR engine with 900 hours on it that had all the schedule maintenance performed on it. I filled up both 5 gallon tanks from a small gas station when I got home. When I first started running machine, I noticed that when I gently engaged the hydraulics on drive motors OR engaged the loader arms OR the auxiliary hydraulics, I got a rapid rattling sound that sounded like a machine gun, or a paint rattle can. But, it would go away when I would increase the hydraulic flow. I assumed it was the hydraulics, possibly a check valve oscillating, but couldn't find any common ground that made sense between the different hydraulic pumps. So, I finally concluded it was a clogged tank strainer or hydraulic filter causing cavitation, and needles to say I didn't sleep well for few nights. I went ahead and prepared to do a full hydraulic oil dump and change filter and clean oil tank strainer (about 50 hours ahead of scheduled time). I just happened to be at the store picking up new diesel fuel cans, and being anal about my equipment and hearing some of the bad stories about diesel fuel, I decided to pick up the Diesel Kleen + Cetane boost and the Tank Cleaner. I added it to both cans, and I went ahead and threw some in the existing fuel in tanks when I got home. Within 10 minutes of starting the machine for the day, the rattling was gone. I thought it was a fluke, but I ran the machine for 3 hours that day without hearing the sound again. After some reading, I finally figured out it had been the engine, and not the hydraulics, making that sound. Wow, did I ever get lucky picking up the Diesel Kleen! I slept like a baby last night. I will use Diesel Kleen and other Power Service Products all the time now.

Have used Diesel Kleen +Cetane Boost ever since. I’ve driven it from N.C. to Honduras three times (8,000-mile round trip). I don’t carry enough Diesel Kleen for the entire trip and can tell a big difference in how my engine performs without it. Less power and a lot more engine noise. As soon as I get back in the U.S. and get Diesel Kleen in the fuel again, power is back and the engine is quiet again. I love this product and will always use it! Just bought some more yesterday.

I am the original owner of a 2001 7.3 Diesel with 450,000 miles and have been using Diesel Kleen +Cetane Boost in every tank for the past 350,000 miles. this truck has never had the valve covers off has zero blow by and uses no oil. I absolutely swear by this product. My truck runs like new. Sure I have had to replace bolt on stuff like water pumps Etc. but the engine is rock solid. I plan to see how far I can go and Diesel Kleen will be in every tank!

Works great, awesome results, great mileage.

My Dodge has 314,000 miles w/ original injectors. It’s lifted wearing 35’s and still gets 18 mpg. Excellent product!!!

My 1997 service van has under 40K miles. I started to observe grey smoke when reducing the throttle under high RPM low load driving conditions. I could also produce this cloud of smoke by blipping the throttle after a cold start. I could also feel mild power fluctuation during moderate acceleration. All of these things indicated fouled injectors.

These symptoms disappeared completely nearly immediately after adding a 16 ounce bottle of diesel Kleen to the fuel. I am surprised and impressed by these results. It’s been my experience that additives are often marketing gimmicks. Not this stuff. My twenty year old Detroit Diesel engine is very happy now.

Thanks!

I use this with every fill-up I use a 1/3 of an oz. per gallon. I get better fuel mileage on the highway I have gotten as high as 55 MPG average city and highway 45. I always try to buy higher end Diesel fuel. I believe in premium Diesel Fuel but it gets harder to find. By adding Diesel Kleen plus Cetane Boost adds another 6 points of cetane to #2 Diesel which I think it is around 48 - 50 cetane

8 oz. per tank 29 gallons. Half a million miles - original injectors.
