I have 175 miles on the odometer and at the 1/4 tank mark. At 175 miles, the needle is usually just a little above the halfway mark. I always check my gas mileage and have been getting about 19-21mpg but the odometer seems a little low and I have no CEL and it drives like everyother day. Maybe its because it's very cold this week but I doubt it would make that much of an difference in the gauge readings. Anyone have some opinions on this...I'll have to wait till the next fillup to calculate the exact MPG...

 

run it close and seee how many miles u can get, i test using 10 gL when its near empty then reset the odom then check it out when ur near E to see if the cars got a prob. anything uder 21mpg id say look into it. try that for shizt

 

I think my worst tank has been about 26.5 mpg and that was probably with a bad ignition coil. I think I was getting 27 - 28.5 mpg with 117,000 miles on the car.

 

check your ecu for the knock sensor code....i first realized mine was bad when i noticed i had awful gas mileage, i really didnt notice any power loss or anything at first, now that its been about 2 or 3 months i notice a huge power loss, especially when my friends 90 max (160hp) was able to keep up with me when i was at WOT
