FUEL COMBUSTION CATALYST
Your classic vehicle can run on unleaded petrol without messy additives thanks to the Fuelstar Fuel Combustion Catalyst. Better yet, you won’t experience valve-seat recession or loss of power, and it won’t cost you an arm and a leg. It overcomes spark plug fouling and is guaranteed for five years or a million kilometres. It’s even been technologically endorsed by NASA. It has an RRP of $184–$299 depending on your engine size, and you can get one through most garages in New Zealand, or direct from fuelstar. com.
