I have a ‘22 6.7 Powerstroke w/27k and pull heavy trailers in FLA. I’m worried about the (disco party). John I believe from the Ford Dealer in Hereford, Tx recommended this. I run 2 oz per fill and will see what happens. I’ve got Five fill ups on it now and seems to help responsiveness. Proof will be in the pudding. So far I’m pleased

Quieter and more mpg in TDI

Size: 1 Count (Pack of 1)

Didn't really believe the hype. Did a little research and watched Project Farm and decided to try. Im not a snake oil guy....but I will say my 2013 common rail TDI is quieter and I get a tad more fuel mileage. Does it pay for itself? Well, it does get better mpg, but I feel the reduction in noise most likely relates to less wear and tear and thats good enough for me. Im only using 1oz per fill up (about 14 gallons) so it lasts a very long time. I get 40mpg and im not light footed.
