My 3400 is about 21mpg or 9 kmpl combined.
Best mileage is about 26mpg or 11 kmpl

My automatic 2.4l is averaging around 22mpg on about 60% highway driving, 40% city.

'02 Ecotec/5spd. 20-22 mpg city; 30 highway. Used to drive a lil hard...but now keeping RPMs under 3k for the past week. Seeing if I get any improvement for city. :P

I suck at keeping it under 3k. I think thinks that why my mpg sucks. Then again my 2.4 auto wasn't a gas sipper either.

I average about 23 mpg on the highway if i drive around 65mph and be gentle. In town i average around 12-16mpg. Ive got the 3.4 with CAI,OBX Headers,MP RACING tuned pcm tuned for headers and no catalytic converter,and 2 and 1/2" exhaust with borla muffler from 2006 C6 corvette.

04PONTIACGA · 06-09-2013, 10:40 PM

OBX headers huh, how do you like them? Most people say they're junk, but most don't even own them.

I know they're not the best quality, but I'm curious to hear your opinion.

03Sleepr · 06-09-2013, 11:35 PM

I averaged 35mpg over about 80 mi a few days ago

02AleroGLS · 06-09-2013, 11:36 PM

Truthfully i like them but installing them was a royal pita! I had to install them twice because the crappy mushy gaskets they give you blew out in a couple of days so i. Went to Napa and bought some metal factory style FelPro gaskets and cut them to fit. But other then that i like them and they flow ALOT better then the stock manifolds in the higher rpms. I gave $400.00 shipped for them brand new.
