The performance and the fuel economy of my Astra 1.6 have completely changed since I put the FTC pellets in the tank. It’s just not the same car as before. It’s really quiet, very smooth and much, much quicker than it was before. You’d never think that something as easy as adding some little pellets to the fuel tank would make such a big difference but it really has. I have to keep my eye on the speedo now as the car is so much quicker since FTC was added! I don’t think there’s anyone I know who hasn’t bought some FTCs too. Really pleased with them. Thank you
