You folks need to re-read what I wrote... its for small engines chainsaws, farm equipment and the like where can sit for months. If an engine calls for high octane premium gas that is what you need to use. Can't see spending that extra money, sell the car!! You can buy additives to boast the octane and I have heard it helps.
I helped my dad on that small farm overhaul a Avery tractor 4 cylinder engine before I was 12 back in the 50s sometime. A engine with premium gas will start better and faster than regular gas that is old and stale.
