Interesting how the article left out that, at least at Shell, premium gas contains zero Ethanol while regular (up to) 10%. Draw your own conclusions...

This is ONLY true at Shell. Everyone else adds ethanol to everything.ElroyJetson wrote: ↑Which is why you don't see it being added to premium fuel.

This is what can happen when RFD users use facts versus opinions they mostly pull out of their ass.ElroyJetson wrote: ↑ Using premium gas in an engine that doesn't require it is NOT going to damage it or make it knock. Exactly the opposite is true.
Higher octane gas is more stable and has a greater ability to resist knocking. It is a higher quality fuel. However it is generally a waste of money to use premium in a car that is designed to run on regular as it is unnecessary, costs more and may reduce your fuel economy because a lower compression engine might not be able to extract as much energy from the higher octane fuel.
Premium gas is a more refined fuel with a higher percentage of high octane components like xylene, toluene and so forth. Regular gas is a very competitive commodity and refiners cut corners by producing a relatively low grade product that is sub-87 octane. Then "boost" the octane by adding up to 10% ethanol - the legal maximum in Canada. Ethanol is lower cost and burns pretty clean - but it is hard on your car. Ethanol has issues that can harm engines, particularly if the percentage was higher, it's corrosive, harmful to rubber, attracts water and acts as a solvent. Which is why you don't see it being added to premium fuel.
In the US you can sometimes buy E15 (15% ethanol, 88 octane). And more recently E85 in some places (85% ethanol, 108 octane) - but this can only be run in engines specially designed to use it. E85 could do a lot of damage in a conventional car designed to run on regular gas.
