Power Service Diesel Kleen + Cetane Boost 64oz Bottle (6 Pack) - Universal Fit, Boosts Cetane Up to 6 Numbers, Cleans Injectors, 10.17536 Liters

Time will tell if effective. Only additive I could find that had any manufacturers approved or recommendations

great shipper and price on product

My diesel mechanic recommended this stuff above all others. The diagnostic test on my truck showed Injector #1 to be just one point below needing serious maintenance or replacement. I used Diesel Kleen during every other fill up. A month later Injector #1 had dropped a point and the others were more balanced too. I bought a case so will keep using it until my next service and provide an updated review.

with the low sulfur diesel , it has little fuel lubricity , so your pump and injectors wont last, eather you pay a little now or a ton to replace later,, we need to go back to good old #2

Exactly what I wanted.

Required if you want your injectors to be clean, fuel mileage optimized and your air pollution system to avoid problems with the "dirty diesel" fuel available in the US (e.g. Europe Diesel is much cleaner fuel). I have used this additive since 2014 and my 3 Diesel Mercedes run great and obtain the maximum mileage I have read anyone obtaining. I use the "white" stuff in the winter when the temperatures lower to 30 degrees and lower to avoid fuel line freeze.

I love this stuff, I use it in my big truck and my pickup.They always ship asap andThe box arrives unscathed.

Great product! Has help restore loss power and has helped to improve fuel consumption! I’m using it in a 2021 Peterbilt.
