There's no benefit from using premium or super unleaded, just stick with the cheap stuff. Oxygenated race fuels will give you an increase in hp, but they'll also lighten up your wallet quite a bit too ($15-20 per gallon :eek: ) .

No sir...all pump fuel are detergent type fuels and all must pass the same purity tests. Run the lowest octane you can without detonation. Lower octane fuels burn hotter and therefore give more bhp. Stock RS50's require no more than 87octane since the cranking pressure is below 100 psi.
