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.
