Diesel Fuel Supplement +Cetane Boost is a winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop, paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine, and water in the fuel can freeze on the facings of fuel-filters, blocking fuel flow. It provides trouble-free winter operation for diesel fuel.

Diesel Fuel Supplement +Cetane Boost is intended for use only during cold winter months when temperatures drop below +30F. Use Diesel Kleen +Cetane Boost (in the silver bottle) for peak performance in non-winter months. If your vehicle will not start or gain power in cold temperatures, use Diesel 911 (in the red bottle).

Justin

Starts great in winter and never a problem.

Andre

Most additives you have no idea if they are doing what they claim, with Diesel Kleen +Cetane Boost you will see a very noticeable difference, quieter, smoother, less smoke, better mileage and better starts especially in colder weather, as long as I own a diesel, every tank will have the Diesel Kleen product added, silver for the warmer weather and white for the winter.

Angelo

My i.d.i. 7.3 idles so smoothly when I use it! Pulls better, better mileage, on a 30-year-old pickup… it’s available everywhere and cost-efficient!!! Buy it!

William Snyder

We increased overall fleet average fuel mileage by 6%. We saw a significant reduction in soot in our oil samples allowing us to extend our oil drain interval from 6k to 12k.
I have included a pic of a recent teardown showing how clean the engine is after 350k of transit use and 12k oil drain interval. All the added benefits far out weigh the added cost of around 3 cents per gallon.

Don Licht

Used in 02 ford 7.3 now in 2015 6.7 diesel. Used for over 150,000 miles a lot of Montana winter driving and not one fuel problem. We used it as directed and recommend it. Worth the money. Our experience is it is an excellent product.

Lane

Tried several types of additives and from what I’ve found this additive worked best for starting as well as most complete fuel burn noticed mostly at idle.

Robin Kelley

Great stuff 8oz goes in every tank full !!!

Don Wheeler

This did prevent my fuel from gelling, but it also made my MPG worse. Winter fuel itself makes your MPG bad, then add this & it made my MPG even worse. In order to gain back some MPG, id have to double the dose. No thanks. No need to use 2x the amount, or add Diesel Kleen to the mix & pay more. I’ll just use another brand anti gel fuel additive in the winter, that doesnt make my MPG worse.
