Is your 6MT and 5AT?? I bet its a 6MT

I am seeing that everyone with a 6MT is getting around 18-20mpg in the city and 22-25mpg on hwy

Where as us poor folks with 5AT are getting 15-17mpg in the city and 19-21mpg on hwy.

I think manual vs. auto make for a big difference in addition to of course other thing already pointed out like additives i.e MTBE or cold weather etc.

Sounds about right iafzal. Mines a 5AT and I think your right on the money. 30 bucks to fill up! Wow...have to remind myself that I'm not driving my Honda Accord anymore.

 

Yeah, mine is a 6mt.

 

Update: So after I reset my ECU after my HG-wire install. My gas got back up over 19. Looks like that did the trick. However, I cannot honestly say if the Stillen CAI + Z-tube or the Hyperground wires provided more benefit. Though, I'm very happy with my mods.

 

Between street and freeway I average 20 mpg with 7000 miles on the car.

only have 3500 miles on car. started first 2 tank fulls at about 20 mpg with 50/50 city/highway. now have progressed to 23.5 mpg for same driving. i stomp on it through first 3-4 gears and drive about 75 mph on highway. but i use all 6 gears whenever i am driving above 35 - 40mph in city conditions. all these things plus the gas you use and the outside temp affect mileage. i use 93 octane premium as well which also makes a difference in the mpg.
