I'm thinking maybe Technosquare did some testing on that too while they were working on the reflashes for our g's couple years ago.
Could be on their site.

IMHO I still think that with the high prices in fuel it does not cost much more each fill-up to use high test as compared to regular grade gasoline. So some people spend a lot of money only to squeeze a bit more hp out of their engines ,so why not give them a diet of the good stuff, to help gain that edge.
GSM- I hope you are warmed up, if you know what I mean.

7 Celcius (45 F) this morning was awful. I can think properly again.

I talk to the service manager and the sales manager of my dealer and both said you DON'T need to put in 89 or 91. You do, however, will lose only a few horsepower. You have to decide if the extra 10-15 % increase in cost of fuel is justifiable for the small increase in horsepower.
So I decided to only use 89 or 91 if I fill like some WOT driving for a while. It does take a couple to tanks for the engine to adapt to the new fuel.

Since I don't drive "HER GEE" that much in the winter and she drives like a granny (But I have to fill the gas), I decided to only use 91 in the summer when I get to let her loose.
I use 91 octane all the time, I like having maximum performance and for the 6 cents difference which is about 3.20$ per tank I think it's worth it. I had an Audi TT Turbo and whenever i put 94 from petro canada i could really feel it. I also on occasion haf 94 octane + the octane booster around 98-99 octane. I thin turbo car would benefit more from a higher octane fuel since more air can be forced into the cylinder.
