Underdog Posted December 30, 2008 Share Posted December 30, 2008 Here's every tank's mileage that I have record of. The last 5 tanks are crazy because I just went on a 1,000 mile road-trip to Ontario, but over the last year (starting at ~27,000 miles) you can see my car has been averaging 24mpg, through 90 degree summers and sub-freezing winters. My 60 mile daily commute is a mix of ~75%hwy/25%city. Stock power, 93 octane. The Crimson Dynamo Link to comment Share on other sites More sharing options...
BoozeRS05 Posted December 30, 2008 Share Posted December 30, 2008 ^ wow, you're a freak.. Good stuff tho.. Then there is something wrong with mine, cause my studder is there randomly from idle to WOT under about 4k rpm. And its cured by disconnecting the battery, and is happy for a week or so. Check that the injectors are OK, and also that the O2 sensors are OK. If one injector is giving too much it may cause the ECU to mis-tune the others. I agree with this.. Check plugs & coil packs too, if you find any problems with the above & you get them fixed, I bet your mpg will increase significantly..

itsme Posted January 4, 2009 Share Posted January 4, 2009 I found I get the best mileage watching my boost gauge. If I keep the vacum at 10 or higher I get the best mpg. It's funny how a slight move of your foot can effect the mpg.
