87 is all you need for the sonata... anything above that is a waste of money and doesnt do anything

However my s2 requires 91 or 94, highcompression motors are the ones that need higher octane fuel

I run 89 with 10% ethenol, it's cheaper here in corn country than 87.

My 78 Firebird on the other hand ran cam2 118 octane "plus" a booster additive. It ran 14:1 compression.

Making the call and gettin' paid for it.

You'll have the least chances of knocking... even if you do start knocking, the knock sensor would kick in and retard the timing... I guess it'll run more efficient.

hmm... come to think of it, I should have used higher octane or at least some octane booster in my car before I dynoed...

I've been thinking about this more and more... seems like a not so bad idea for me to start using something better than regular - due to the advanced timing in the flash. Probably only cost $3 more on average per fill up.

C&D did a test a while back as well... Ram and Mustang actually gained some hp, while the V6 Accord lost a few % in power/performance.

YMMV... but you probably wouldn't notice the difference. You're fine which ever one you use. In most cases, I would assume the engine will run more efficiently.
