RACE Gen2 fuels (Except RTR20 Gen2 and RTR33 Gen2) are blended with a 50:50 ratio of synthetic to castor.
So it would seem that 9% total oil would be 4.5 % castor and 4.5% synthetic.
When talking to byrons co-owner at the byrons challenge he was telling me all byrons fuels use a minimum of 6% real castor oil , hmmmm interesting . Gonna have to call Ryan tomorrow ,
