eek, usually $35-37 of 91 oct in the RX8 and I usually get about 200 miles out of it, unless I do highway driving... then I get about 230-250.
Probably would help if I wasn't shifting at 7-8k RPM's.
Oh well, my car was meant to put around.
I've been looking at the new Xterras and Pathfinders...maybe it's time to upgrade.
