.justin. Posted May 9, 2005 Report Share Posted May 9, 2005 I've seen as high as 20.5 averaging 65mph, but my usual day to day sitting in 20 minutes of stop and go traffic then running it hard to make up for being forced to drive slow gets me about 14.5-15mpg Link to comment Share on other sites More sharing options...

vtodd82 Posted May 9, 2005 Report Share Posted May 9, 2005 i can average around 14-15 when iam driving easy. on the highway at 60-65 i can sit anywhere from 17-23 mpg depending on how hard the winds blowing/grade of the road, etc. my display says 13.5 though. i guess i floor it too much Link to comment Share on other sites More sharing options...
SSUPERSSPORT Posted May 9, 2005 Report Share Posted May 9, 2005 Last fill up 14.4 on display, 14.04 actual. Most of the time actual average is 13.7. It could get better mileage, but hey, that wouldn't be much fun! Link to comment Share on other sites More sharing options...

Big O Posted May 12, 2005 Report Share Posted May 12, 2005 I get around 13mpg, mostly in town, lots of stop-and-go traffic. And according to the owner's manual, 87 octane is fine. They recommend 91 in the 6.0HO to achieve maximum horsepower, but 87 is fine. <{POST_SNAPBACK}> You might want to do a little more research. <{POST_SNAPBACK}> Educate me please. <{POST_SNAPBACK}> Lets see ... here we go 87 --> Not FINE 91 --> FINE easy as that ... no charge Link to comment Share on other sites More sharing options...

jchitwo Posted May 12, 2005 Report Share Posted May 12, 2005 Just finished my 5th tank after installing my CAI.... I'm running on average about 15.1mpg at the pump, i was running at about 13.9 .... of course my DIC say's i'm gettin about 16.3 but that seems to always be a little off. My latest trip to cali, i got somewhere around 18mpg at the pump as long as I kept it under 85mph, anything over 100mph...i got about 13...
