Default Octane

I was just wondering what gas everyone uses in their car. Is there any advantage using a higher octane gasoline in a N/A engine? I know it is better for higher compression engines with F/I, but is it any better than regular for non-supercharged models?

Actually lower octane provides more power, but it combusts easier, which can give you KR if you're running hot. Basically use the lowest octane you can without knock.

None. All octanes have the same detergents within the same brand.
