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

great product at a great price! ive used power service for years in our fleet and it saves us money in the long run. Helps to keep high pressure fuel pumps lubricated and running smooth. Ive also noticed a slight increase in MPG. I would recommend this product to any one with a large fleet or even just a diesel pickup. It will save you headaches down the road!

Great for your Cummings or any diesel really and great buy in bulk like this saves you money. Helps with that extra boost and running great and clean.

Diesel kleen works i am getting 140 more miles per tank full , could the injectors be a little dirty. Probably yes, the best way to buy diesel kleen is to buy the six pack at 64 ounces which gives you three gallons of diesel fuel kleen, not unless you like spending all of your money, smaller containers cost more, i ask Volkswagen is there any better, they said yes our product, it’s more expensive .

This is an excellent product and is the only tht I use in my tractor and pickup when it comes to fuel treatment!!!

Great deal great product Quick delivery

This is a great product and really increases the performance of all my diesel vehicles. The only complaint I have is that once the container is opened, if you don’t use all of the contents and close the lid, it will leak if it falls over or is laid on its side. This happens no matter how many times you reset the cap. Other than that, this stuff is awesome and definitely enhances engine performance.

I'm a big fan of this Diesel Kleen. Been using it for 15 years. Buying this six pack saves you about $5 per bottle.

I add this to my fuel barrel when it is filled to help with lubrication. This is cheaper than I can buy it locally.
