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

I’ve used this product for years not just in my truck but also my skid steer. It does what I would expect by keeping my injection system running smoothly. It was recommended to me by a fleet manager at a CocaCola bottler who said it cut repairs by a third on the diesel delivery trucks they have.

Helps engine run smoother, seems to increase fuel mileage a little. I add at every fill up. Multiply gallons to fill tank by .4 and that equals number of ozs to add.i keep graduated plastic cups in large ziplock bags for cleanliness. Keep a funnel in ziplock bag for cleanliness and to keep diesel clean off truck interior. Makes usage easy and accurate to Cummins recommendation.

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 .

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!

I will be good for a while now. Gr8 product to to boost my Cetane and lube the fuel system!!

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 use this in my 2003 Ford F-250 with the 7.3L PowerStroke. I get better fuel economy, smoother running and quieter engine. Fantastic price, and came professionally packaged in a case of 6-bottles. Highly recommended!
