StarFire engines are economical to run and will travel approximately 100 K’s on one dollar of two stroke petrol mix.
It is recommended that a run in period at low speeds of 15/20 kph on short 20/30 minute journeys to prevent engine over heating, be observed. When your StarFire Engine has been run in, this will give longevity of engine life, better engine performance and extra power with a lower fuel consumption.
During the run in period, we recommend strongly, that the petrol to oil mix for your two stroke engine be…18 parts fuel to 1 part of top quality synthetic two stroke motor oil. After your engine has been run in, you can change the petrol to oil mixture to…25 parts fuel to 1 part of top quality two stroke oil such as Castrol TTS or Castrol R30 or Shell Advance.
