I notice a much larger difference going from ethanol fuels to non ethanol if you can get them.
Anybody run the octane numbers?

My small seasonal engines appreciate that too.
Looked at the pump today- $1.29cdn/L 87, $1.48cdn/L 89.
It buys me 15-45 more miles per tank. I've averaged about 26 mpg over the time I've owned the car. It comes down to the difference between the cost of regular and premium, which has varied a great deal. In other words, sometimes it pays.
My neon always runs smoother on midgrade gas. Part of it is I'm fairly sure that the idle air control valve is bad which is common.
No 93 around my neck of the woods, 91 is the premium stuff.
I run 91 in the FJ09 triple and the supercharged triple Scarab jet boat, 89 in all the yard implements except those that are 2-cycle. Those get the pre-mixed 50:1 or 40:1 stuff from the cans, as called for.
I don't even run 87 in the loaner vehicles from MB or BMW when either of mine are in for recalls or warranty work, or rental vehicles for that matter.

Same here; I put Shell 93 in the GLC 300 loaner I had while the C43 was in for its Service A.
I do the same… the rental jeep said 87’s fine but 91 or 93 for best performance so it got 93. Quick land yacht, assuming the EV battery was charged.
Truck recommends 89 but says 87 is acceptable. It lives on 89-93. Van gets 87, e15 88, or E85 depending on price, it doesn’t care.
