Martin, This is for specialist racing applications.
In fact, it's a good demonstration of the difference.
Tony obviously knows all about fuels for PAWs, but this fuel is very different from the general mixes that HE recommends in the instructions, when you purchase a new PAW.
In UK "Phantom racing", races have been won by PAW 1.49s running on virtually no oil, but the engine needs a rebuild after the race...
