Hmm. I haven't really seriously considered putting higher octane gas in my car until now. It says premium, so I give it that, but I hadn't really thought to track down one of those Sunoco stations.

My car has an 11.5:1 compression ratio. But OTOH, the ECM is really configured for 91-93 octane gas anyway, so maybe it wouldn't know much what to do with 110.
