I've been logging with mymilemarker.com since I got the '07 a month or so ago and have been averaging 17.5 mpg.
280 mile trip - had about 20 miles of "city" driving. Car's computer says 25.2 mpg. I registered 16.7 mpg for the first ten miles before I got on the highway. I had the cruise control locked in at between 75 and 80 for about 90% of the trip, and around 80-85 for the rest. Although about 100 miles into the trip, I did decide to stand on it from about 70 to 110 mph and watched the avg mpg drop from 25.6 to 25.2 almost instantly!
Only mods are SLP LM's and K&N air filter.
HA ....I must be a real moron lol, because I don't beat on my car or anything, but I am getting 18.7 right now. (I live in northern ohio where its 30-40 degrees right now). Thats from 70-80 mph Best I ever got was 22 in the summertime. .... I am putting in the cheap crap...should i step it up to 89 octane? I know the car would probably run better on it. Thanks
