Power Service 03850-02 Diesel Kleen with Concentrated Cetane Boost Formula - 2.5 Gallon

Great additive for diesel in semi truck i use it in my 2023 KW 680

This stuff seems like it works I run a lot of it I'm on my 14th two and a half gallon jug however the injectors still clogged but that could be because of the poor design of the new Peterbilt 579

Very Satified

I'm a regular user of this product and if you're a diesel driver, you really need this stuff, especially if you have a common-rail machine with high miles and don't want to spring for a new set of injectors ($3K-$4K) on your high-mileage coal-thrower, (I've got 300K-miles on my original set of injectors)and this stuff all but eliminates the noticeable "click & chatter" typical of common-rail injectors. I've noticed it mostly at cruise speed and it makes the motor sound as it did when it was new. You only need 1-ounce per 3-gallons of fuel. Any more is a waste of this really great stuff. Buy it inbulk like this 2.5 gallon container and your cost per 35-gallon tank of fuel is only $1.28(Assuming $140 for the container and dividing 320-ounces into 960 gallons at the recommended 1:3 ratio; how they figure 2.5 gallons will treat 3,750 gallons is, well, a stretch), and the increased mileage is noticeable if you do alot of highway driving. I get about 1-additional mile to the gallon. Try it, you'll love it!!

Very good
