Power Service 64 Oz. Anti-Gel Diesel Fuel Supplement with Cetane Boost - 1 Each

Great stuff. Been using for years. Keeps fuel from jelling in cold temps. Helps keep injectors clean too.

Working very well

As ordered very fast shipping

Treats the fuel in my truck.

I’ve used Power Service Diesel Treatment for 28 years in my Ford Powerstroke and it still runs great. I use it in 3 other diesels and am getting great results. Will never buy anything else for my trucks.

I do not use my truck very much and keep months-old fuel. The YouTube oil geek knows lubricants but opposes additives as a general rule. Others have tested fuel additives and rarely support any of their vendors' claims, usually through non-standard tests that the presenter invented. This is one of the few brands that treats 250 gallons for a similar price. Most but not all competitors improved injector lubrication. Failed injectors would cost me more than the value of my truck. The geek noted that my motor manufacturer only certified one brand using industry standard testing, evidenced by the Cummins "C' on this label. Because I leave the same fuel throughout the year, I chose this version that prevents winter waxing.

Forgot to use in my diesel truck this winter. Sure enough diesel gelled up during the first polar vortex and truck wouldn’t run. Put this in and have had no problems since even though temperatures outside got as cold and even colder than before. Great product.

Great product helps tremendously
