Default Re: Shell 93 Octane "V-Power" vs Ethanol Free 91 Octane

The way i look at it is, 93 will be 93 and 91 will be 91 in terms of making hp/octane rating. In the end 93 will be stronger you can say.
Factory performance cars are tuned for 91 and dont show any gains for 93.
I personally go 91 no ethonal for the simple fact it is cleaner and for storage.
When i race the car i throw in 93 for a little extra knock protection. Its cheaper too!
