Dominic, you're gonna hate hearing this, but I have gotten as high as 31.0 MPG in my former 98 Formula 6 speed! And I know guys with these cars that have gotten 32-33MPG! So to be honest, the MPG on the V6 f-bodies is really only better in the city.
That makes sense, especially in Canada. I really like the LT1 engine, especially since its an iron block beastquote:

On long highway trips in my LS1 I would run 89 octane though, and could have easily run 87. At a steady speed in 6th gear, on flat roads, there would be no need for higher octane fuel.
Speaking of octane, now that the cold weather has arrived and it's not getting above 50F during the day, I've switched to running 89 octane in my LT1. No need to spend the extra money for wasted octane. I know I won't get any spark retard in the cold weather using midgrade like this.
