Sticker on my 07 6spd says 17/25.......sticker on my 08 automatic says 19/25.......glad I don't live anywhere near the kinda city they base their test procedures on.....

No question that if you took a long trip & could control yourself & keep them at 70 mph they will get 26 to 28 mpg. I got about 26 on a trip where I took it over 130 mph.

Pure premium seems to make about a 1 mpg difference over the 10% ETOH blends.

I think with pure premium that if you took a trip & kept it at 60 to 65 mph....someone might ave 30.
