I was told about FTC by a lady who comes into the coffee shop I run, the week I bought my little Citroen. The car had been owned from new by an elderly gentleman who only driven a couple of thousand miles a year and was a bit hesitant and juddery at times. I put the FTC pellets into the fuel tank while I was filling up. Within a few days the car was much quicker off the mark and much smoother to drive. Absolute winner, thanks FTC!
