Ford Genuine PM-22-ASU ULSD Compliant Cetane Booster and Performance Improver - 8 fl. oz.

Safes your engine from those cold morning starts and wax build up

This stuff is the bomb! It works fantastic to take out the knocking and pinging in my 7.3 Diesels. Use 8oz to 20 gallons of fuel. Have been using this product for several years and when I miss a tank you can really tell the difference. Use it consistently to improve the performance of 40 cetane diesel fuel. Wouldn't go without it. Tak it with me when on long trips to remember to add before filling up.

Been using this product for years in myFord diesel 6.0 at every fill up. Provides benefits such as increased cetane and increased lubrication. Keeps your injectors happy and may even increase your MPG slightly.

I highly recommend Ford Motorcraft Cetane Booster for all diesel engines. The quality of diesel fuel sold at most filling stations is poor quality when it comes to cetane ratings. Ford Motorcraft Cetane Booster improves fuel economy by a minimum of 1-2 mpg with regular use, improves engine performance and helps keep my engine running smoothly. I have been using this product for nearly 10 years on a regular basis. Worth the money!

I’ve been using this stuff since I got my truck years ago. I run it almost every time I fill up unless I’m traveling far away from home. I can tell you that my fuel filters are always clean and have very limited water, which I’m not sure if it’s this stuff or good quality fuel. I’m sold on using this to help lubricate the cp4 and will continue using it. The only reason it doesn’t get 5 stars is it doesn’t have the measuring bottle like some of the competitors.

Ford dealer said I need this for my fuel injector on a 2016 power-stroke and Amazon carries the OEM product in 3-packs. That is a story with a happy ending.

I bought a used 2016 Ram with Ecodiesel engine, and I discovered the dreaded lag when the engine is cold. I filled up on fuel thinking the diesel might be old, and I installed a remote start system and let the engine idle for a bit before driving. It wasn't until I filled up again and added this stuff that I noticed the lag is significantly reduced. I can't say definitively that it was this stuff, but it sure is looking that way.

Good product
