Diesel Kleen + Cetane Boost 64-oz 6/1 per Case

Hells to the yeah, this stuff rocks. It's the only fuel additive I trust to put in my dodge ram Cummins, and it does not disappoint, can't go wrong here A !!

I've started using this in a 2019 Cummins ISX Efficiency series motor in a 2019 Lonestar and I actually think it works. I use a gallon a week just to try and I like it.

This is an add plus for performance with all our diesels. The Ctane boost is noticeable with the MPG. We don't get quality diesel fuel in this country anymore but this boosts the performance close to diesel red. There are a couple other additives we use but Walmart doesn't carry those.

item received as described. online price better than in-store, and online version had qty packaging vs. single item only in-store.

I run this product with the High Performance Renewable diesel fuel in my tank. Perfect combination and increases mileage and performance!!!

I have a 20 yr old diesel truck. I use this and get better gas milage and hope ir keeps my engine clean

Excellent additive. Only diesel additive approved by Cumins. I haven't noted any change in fuel economy yet, but I have only been using for a few months. Engine seems to be running smoothly.

I ordered the item, very easy, sale was no problem. Pickup was very quick with any problem. Will order some products again.

Product is easy to use and I believe it helped with the new Smog requirement on older diesel motors. my particulate count was well below average after using this product every other fill up for more than a year now.

I have always used Diesel Kleen in my diesel engines and have had great results in clean injectors. I started using the product back in the 80's when I worked in the steel mill for all our equipment and it worked keeping our equipment running efficiently and had fewer mechanical issues winter and summer.
