SAE High Octane Fuels Symposium: Is a new high-octane fuel a pragmatic pathway for higher engine efficiency in the US? (part 2)

Green Car Congress

Refiners would continue to produce two high volume products in the gasoline boiling range: the Exx BOB (Blendstock for Oxygenate Blending) would have a low octane requirement (e.g., Gasoline or E10 BOB would be premium-grade fuel for total coverage of legacy fleet. RON ~85), and be inexpensive for refiners to produce.
