Genuine Ford Fluid PM-22-A ULSD Compliant Cetane Booster and Performance Improver - 20 oz.

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!

The best additive I have used in my 2008 powerstroke (6.4). I have noticed that the regen isn't running as often - this is a BIG PLUS! Gas mileage improved by about 1 mpg. Not much, but I don't drive like an old lady, either. I haven't towed with it yet, so we'll see if it helps there. However, I am happy with the results so far.Really, I have tried everything. Optilube, Stanidyne, etc. etc. Some seemed to have absolutely no effect whatsoever. Some helped for a little while and then seemed to fall off.I've used this product now for a few months, now. Drove a long distance for vacation and it helped quite bit. Usually, by the end of a long day of driving, the turbo boost stays fairly high. I believe it is likely the DPF is not clearing as quickly, so the engine must work harder. This time, the boost stayed lower for the entire length of the 400 miles. I will be towing in a few weeks and that'll be the big test. Either way, I'll likely use this from now on.

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 use this every time i fill up. Dealer says my injectors are spotless.

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.
