I’ve had experience with fuel catalysts going back many years. In the 1980s I was the workshop manager for a major high street electronics chain, looking after a large fleet of commercial vehicles. I was involved in the testing that was carried out on fuel catalysts in our fleet of Scania & MAN lorries. There was no question they made a big difference. I’ve seen first-hand the reductions in exhaust and smoke emissions and also how clean the engines and oil remain with long term catalyst use. I have continued to use and recommend fuel catalysts for many years, which is why FTC is used in all our family vehicles.
