You have a forced induction engine with a fairly high compression ratio
..and you're saying it's more efficient with higher octane fuel eh?!?
Ah octane threads..
You're not imagining things. What's occurring is the lower octane fuel is causing detonation / knock.
Your engine management system is like whoa.. fuck this shit.. so it pulls timing and possibly drops boost.
When it pulls timing.. spark is occurring at a less optimal threshold.
This allows for the fuel to cool down the cylinder and help prevent detonation
Otherwise it could lead to a domino effect.
The consequence of this is reduced power and inefficient burn of fuel.
In many cases, unburnt fuel is actually sent down the exhaust where it does damage to your primary cats.
Again, you and the misses are not imagining things.
Using lower octane is shitting on your powahs and mpgeees.

So, it was just recently that I found a few that carry 94-grade (called "ultra" grade). And yeah, seems the car does perform a bit better. Thanks!

If the cars says required, then don't cheap out on the gasoline and go with a lower grade. In my case, I just wanted to make sure that despite going with premium (91), is something with even more octane even better or just my imagination.

That's marketing bullshit
Honda says required and recommended for the same engine in different cars in the same segment
You'll see the real world tests prove that the lower octane has reduced power and mpg
It's because cheap ass buyers don't want to buy a car that says premium required
Lead marketers tie off with the chief engineer, will it work? Yeah but.. okay cool!

LMAO...
I was raised by a European hippie...I'm open minded as fuck but...
no...not that. I don't share and I don't want anyone else when I'm in
a committed relationship.
I did have a slew of 2 week committed relationships in my 20's though.

You know if I could have any one of your 6, or so, vehicles it would be the Ody.
