Whats up g37 family... question... i have a 2010 37s coupe, my average mpg was about 15.5 both before and after my mods.. (short ram intake and deleted muffler/custom straight pipes but i never deleted the cats) recently iv notices im barely gettin 14mpg and im not beating on it as hard as inused to? Any suggestions on y the sudden decrease in mpg?
Thanks

 

Try cleaning your throttle bodies maybe?

 

Thats weird. Auto or 6spd? I am 6MT and I get avg. 23 mixed driving and I get on the freeway like a bat of hell. Other than that I drive civilized. What are your usual driving conditions?

 

I feel your pain the only mod I have is some 19's and I average around 15ish all the time. But I have seen myself average 26 on long highway trips!

 

Yeah brotha the struggle is real im back on stock 19" enkeis but when I had 20x11s on it i was doin a lil better due to not driving as wreckless however yes im consistently at 15mpgs highways 18mpg tops

 

How!? LoL

I seriously must be lucky cuz I am consistently between 22.8 & 23.5 mpg for mixed driving. Mostly 23 mpg but you get the point. I don't understand how you guys are having such low mileage

 

City driving. If I get on the highway and keep it under 70mph I can manage 21ish.

My usual is all city driving, short trips. ~15.9 weekly.

 

I would love to hear you exhaust tho

 

City does kill my mileage but I still manage to keep it high. I cruise the freeway at 70 on the dot. I still can't imagine why you guys have such low mileage. I hope you can figure it out. You auto or manual?

 

Idk. I mean, I dont really baby my car so there's that.

 

Yeah man that could do it! LoL

These bi+ches are thirsty under throttle. Thats why I usually only punch it getting on the freeyway. But that right there is your problem. Try one week, not flooring it, you'll notice a difference. Do you drive with the MPG/Range screen up? I do and it helps keep me out of the throttle...its almost like a game. I try to beat my last score but I usually just break even. Good luck though

 

I understand trying to save gas, but I bought the car because its a sports car. The poor gas mileage wasnt even taken into consideration when I bought it.

 

^^^Thats fine. Info was basically for the author of the thread...he seemed to be worried about the mileage! LoL. I got lost talking to you and the comment looked pointed at you. I too didn't care, but I was actually impressed at getting 23 avg. Especially how I drive normally

 

Maybe everybody's frame of reference is different, but as partial as I am to the G, I consider it a grand touring coupe. I've owned a sport car or two over the years, and the G does not qualify in terms of form factor and torque, nor HP. Not knocking the vehicle at all. I love it for what it is.

Regarding fuel economy, I can squeeze 27 on wide open interstate, but I can also get it down to 13 in the city driving like I stole it.

 

I mean would you consider a 370z a sports car? They're the same thing just one has leather and is quiter
