I’m writing to let you know that I’ve noticed a marked improvement in my Golf TDi. The FTC pellets have made the car a much quieter and much smoother to drive. Before adding FTC, I was averaging around 50 miles to the gallon but now it is in the region of 55 mpg, so I’m exceptionally pleased with that. The biggest surprise however has been in terms of acceleration. The car is noticeably more responsive and has been ever since I added FTC. I’ve added FTC to my wife’s new Polo and into the petrol mower. When I took the mower this March it started first time having sat unused for many months.
