I first used FTC in my Ford Ranger and saw a big improvement in fuel economy and towing performance, so it was a no brainer to add the pellets to my Nissan Navara. Having done just over 1,200 miles since I added the pellets the average fuel economy has increased from 32 to 35mpg. Just like the Ranger there has been a big improvement in performance and there is now no black smoke when accelerating hard. FTC pellets are money well spent in my book, which is why lots of my friends and colleagues have started using them too.
