sonyman87 Posted September 12, 2005 Report Share Posted September 12, 2005 ~15mph city (lead foot) ~25mph highway at 65-85mph with some city. on 93 octane both those numbers hurt. Quote Link to comment Share on other sites More sharing options...
Redwolf Posted September 12, 2005 Report Share Posted September 12, 2005 ~18 city, ~25 highway. I got 30 highway on cruise before, but I think that just on little drives I'm getting 25. Nowadays, I'm getting infinite mpg, since I'm not driving right now. That'll be softmore year when I start again. Quote Link to comment Share on other sites More sharing options...

fastbird232 Posted September 12, 2005 Author Report Share Posted September 12, 2005 Holy shit. I'm averaging 24 with 90% highway, 10% city. How are you getting nearly 30? Quote Link to comment Share on other sites More sharing options...
Kalgorn Posted September 12, 2005 Report Share Posted September 12, 2005 WTF... must be nice. I was surprised to see I pulled over 19 the other day. THat was with a couple runs at WOT with my airbox out though. Even so... oh well. I changed out my air filter becaause it was so bad so I'm just gonna have to drive like a grandpa and see what I can do. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted September 12, 2005 Report Share Posted September 12, 2005 I got 36 MPG on the way back from Kentucky. Haven't driven it around the city much to get a good figure on that. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted September 12, 2005 Report Share Posted September 12, 2005 16mpg mixed city and highway. Hopefully a new AC compressor will help. Quote Link to comment Share on other sites More sharing options...

sonyman87 Posted September 12, 2005 Report Share Posted September 12, 2005 Holy shit. I'm averaging 24 with 90% highway, 10% city. How are you getting nearly 30? you have a 3.4dohc not a 3.1 or 3100 Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted September 12, 2005 Author Report Share Posted September 12, 2005 I'm aware, but other 3.4L owners are getting around 30+. Quote Link to comment Share on other sites More sharing options...
Kalgorn Posted September 12, 2005 Report Share Posted September 12, 2005 THat was with a couple runs at WOT... That might be the problem... Right, but I remember driving like a grandpa before that and I only pulled 18.5 MPG. But that was before the air filter change so that seems to have helped a lot.

Afubar Posted September 12, 2005 Report Share Posted September 12, 2005 fastbird - I have no idea how I got that kinda mpg. Cause I sure wasn't taking it slow. I was trying to get to the airport and it was 180 miles away and I only had 2.5 hours to get there to catch a flight. I almost made it, only missed the flight by 12 minutes. It surprised the heck out of me. I do keep her tuned up, regular oil changes, belt changes, frequent checks of tire pressure, maybe it all helped. (Oh, spent too long driving the autobahn in Germany, fraid I have a really lead foot) lol I do have the 3.4L Quote Link to comment Share on other sites More sharing options...
JNGTP94 Posted September 12, 2005 Report Share Posted September 12, 2005 13 city maybe 19 highway Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted September 12, 2005 Author Report Share Posted September 12, 2005 What's the method everyone's using to gauge mileage? I fill the tank and reset the trip odometer, drive for awhile, then fill up and divide the mileage on the odo by how many gallons it took to fill up again. Are you guys using the DICs?

GnatGoSplat Posted September 12, 2005 Report Share Posted September 12, 2005 That's how I did it. Now I use the trip computer because I've got it within 1% of my calculations. Quote Link to comment Share on other sites More sharing options...
MoTox8410 Posted September 14, 2005 Report Share Posted September 14, 2005 23 highway 17-18 mixed Quote Link to comment Share on other sites More sharing options...

z34_nut Posted September 14, 2005 Report Share Posted September 14, 2005 over 30mpg highway (31-34) and about 18-24 city, depending how I drive it. Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted September 14, 2005 Report Share Posted September 14, 2005 over 30mpg highway (31-34) and about 18-24 city, depending how I drive it. :withstupid: Shines at over 30 on the highway.. but sucks hardcore in the city.. usually 16-18.

TeeJay3800 Posted September 15, 2005 Report Share Posted September 15, 2005 Most of our city mileage seems spot-on. They're really not bad at all. My window sticker says 19 city/30 highway, so 16+ is really pretty good. Quote Link to comment Share on other sites More sharing options...
