Diesel Fuel Supplement Antigel 64 oz., Pack of 1

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

Great product helps tremendously

Treats the fuel in my truck.

Best stuff out there! Even lab tests prove it... all I use (21 f350 6.7 super duty platinum)

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.

Very good product

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.

I use this every winter to keep the fuel in my old !980 Mack from gelling while it's in storage and it works.
