I took a drive for a couple hours today, and found a station near the State Line Speedway selling 110 Octane. The pump also had 87 Octane regular. (In fact, they only had the two grades, no Premium or 89, it was a little mom and pop place, the store attached to the station is a beer and wine store).
So, my questions are this. Would putting 110 Octaine in a stock G37x Coupe be...
1) Something nice to do once in a while as a "treat" for the car so to speak.
2) Not hurt it, but be a waste of money since anything over the local 92 or 93 local Octane is good enough, and gains had at 110 Octane are nil or minimal.
3) Actually cause damage somehow and unless you're running an actual race car at the local track you're an idiot to put it in the tank.
As an aside, no I didn't put it in.
I just pulled into the parking lot, looked at the pumps briefly, got out of the way since the place was somewhat busy and drove on. I didn't even go into the store to talk to a clerk.
Anyway, thanks in advance for replies, and if this belongs in another section then of course please feel free to move the post.
