What is the octane rating of ethanol free gas

This 95 Octane Unleaded Gasoline contains no alcohol at all. This means 0 ethanol content which makes it ideal for limited use engines as well as seasonal use equipment.

Premium gas doesn't provide any more power or contain better additives than regular gas, and it contains the same amount of ethanol as other grades. It just resists detonation (knock) better than lower-octane gas—nothing more, nothing less.

Even if mileage efficiency is reduced by 3%, ethanol-free gas is better for the engine. There have been reports of ethanol mixed gas leading to rusting engine parts. Ethanol, by nature, attracts water and can cause damage. There are gas stations across the U.S. that offer consumers a choice of ethanol vs.

According to Dan McTeague, a noted petroleum analyst, Shell and Esso 91 are both ethanol free. [UPDATE: Chevron notes on its website that in some locations in Canada, its Supreme Plus 94 Octane fuel is also ethanol-free, as of 2022.
