The FTC pellets arrived very promptly and I added them to the tank. The change in performance was noticeable within a very short time. Where before, there had been a little lag and hesitation, there was now just instant power. I’d assumed that it might make a bit of a difference but not as big as this. In a heavy 4x4! It’s no understatement to say that the car really does go like a rocket now. And in terms of emissions, first thing each morning I used to reverse up my driveway through thick clouds of black smoke, but now, there is nothing! On the first long run for work there was also a very noticeable increase in fuel efficiency which, when calculated, equates to well over £20 on a full tank. So, the car is doing way better mileage than it has ever done before!. Just by adding some little pellets to the fuel tank, the car has been completely changed. It's faster, smoother, has way better acceleration and fuel economy and there is no black exhaust smoke anymore! Jack, a friend of mine bought FTC at the same time as me. He called to ask what I thought but, before I could say anything, he said, “Tim. I’m gob-smacked at the difference they’ve made to the performance”. All the lads in the local have now got themselves some pellets and many work colleagues too. It’s fair to say that I’m still astounded how well FTC works.
