Is oil mixed with fuel? What type of fuel and octane rating?
Oil must be pre-mixed with the fuel. We recommend CastrolTM TTS two-stroke oil (available worldwide). The engine’s Electronic Control Unit (ECU) is programmed for Europe and North America to accommodate slightly different octane ratings. We recommend using the highest octane alcohol-free unleaded auto-fuel that is available. This is generally 98 RON (Research Octane Number) in Europe and 93 PON (Pump Octane Number) in North America (except California which is 92). Always try to use a brand of fuel without ethanol and alcohol additives (minimal quantities up to a few percent of these additives are ok). Fuels with MTBE additive are acceptable. If fuel with zero or minimum ethanol or alcohol content is not available, then AvGas (100LL) is acceptable (may require more frequent sparkplug changes).
