Notice that he drives a motorcycle. Most bikes are better with premium because thats what they need to run at maximum efficiency.

If a car asks for 87 (regular) octane fuel pumping higher octane fuel will only retard the timing thus reducing the performance and efficiency of the engine.

I would not pump premium fuel in a vehicle unless it is recommended to do so.

As far as ethanol-free gas goes, Petro-Canada and Shell seem to be the only brand in Atlantic Canada to carry it.: in all grades that is.

I've only pumped fuel that included up to 10% ethanol twice and DID notice the difference in MPG although I do not have enough data collected to experience different brands of fuel. I fill-up at Shell 98% of the time.
