Power Service Diesel Kleen +Cetane Boost - 12 Ounce (Pack of 9)

Well known brand. Great reviews. Seemed to do the job. Convenient to use. Cummins approved which is a plus.

Fast delivery and decent pricing. This stuff does work,I add this to my fuel 1 time per month.

Great stuff to add to fuel to help keep injectors clean and working properly!

Been using this stuff for the past 13 years in my 2010 Ram 2500 Cummins B67 and in that time I've logged over 150k miles with zero issues. The added cetane does provide a slight but noticeable increase in power. Typically I'll add about half a bottle to a ~30gallon fill-up.

Originally purchased as a package of 12, at what was originally thought as a discount. Ended up being advertised wrong. Great communication and was made right on order. 12pack purchase is a great value compared to a few box stores, will definitely purchase case quantity next time for future use.

Excellent product. Also, each bottle is the exact amount needed. You don’t have to measure. Easy to carry and utilize on a trip.

Good for engine..

My 2004 Dodge (Cummins) has 148,000 miles on it, and I bought it new. I could hear the injectors rattling more after about 130,000 miles, so I started using Diesel Kleen every few tanks. It really quiets them down, and the engine runs better on Diesel Kleen as well (smoother and feels like a little more power). I really like the single use bottles, since I can keep one in the door for when I need to fuel up.

By the 3rd bottle my fuel mileage increased by 5L/100km Truck seems to run smoother and slightly more responsive

Great product for storing diesel truck during winter and protecting fuel system
