every time I fill up my car, I suspect all the different octane gasoline are exactly the same, 91 octane. The only difference is what it is called (eg. gold) and the price. Gas company puts in the same octane gas, with a little advertising, gets more money by calling it gold or premium plus. It is all marketing. Unsuspecting driver feels better buying higher price gas for their beloved car. Any one likes to comment.
I'm sure that is so. My car says to use premium on a sticker right next to the gas tank opening. But I don't recall seeing anything about using premium in my motorcycle in the owner's manual or on the gas tank opening.
On regular gas, my motorcycle gets over 80 miles per gallon.
Correct. Sort of. In WWII, aviation fuels were made up to 150 octane rating. Aircraft engines used superchargers, (more than one in some cases) to massively boost compression ratios and therefore power. Use of low octane gasoline like current 100LL will not allow full use of the superchargers.
The Jap Zero of WWII was the premiere fighter plane of the skies in the first couple years of the war. A Zero weighed the same as a modern SUV, but its radial engine put out 950 horsepower. If you can imagine an SUV with 950 horsepower, that’s how potent the Zero was.
