Well I went from about 25.7MPG in August/September to around 24.1, is that normal for a roughly 30 degree temperature drop?

 

They change the gas formulations with the seasons too.

 

I've lost nearly 4mpg in the last month. The cars running great so I don't think it's any problems, I think it's just the weather. I was getting 29ish in mixed driving. I'm now down to 25mpg.

 

Looks like you guys are getting better mpg then me. I'm getting about 24-25mpg on the street if i'm on the freewa i do about 80 i get 28-29.......I'm also in Ca and i'm driving a stock 07 s/c

 

i get 20 if i'm lucky...

 

i get 18 mpg...it sucks wanker. i do drive pretty hard and there is a traffic light every 200 feet...its gay but what can i do.

 

Move . ?

yah i have noticed that my MPG have dropped about 1-2 the last couple of weeks...of course i've been driving like an ass too

 

be sure to check ur tire pressure also. last time i corrected mine and made a huge difference. (almost 5psi to every tire) fuel econ dropped from 11.5L/100km to 10.4L/100km

 

Ok, so it's not that I have been drivin harder. lol..I went from around 27mpg on my 07 SS/SC to an even 24mpg. Crazy cold azz weather.

 

Mine has dropped a little. I'm getting 18-19 MPG. City driving FTL! Most trips I make are 5-6 miles. I try to take notice what my average MPH are also and it usually ties in with my MPG. Does anyone else reset the MPH every time they fill up. My average speed has been around 20 MPH. Does wonders for killing mileage.

 

I am in south florida and with the recent drop in temp from the mid 70's to low 60's my mpg has dropped at least 1mpg and that is over a week span and 1 tank of gas. I usually get about 23.5 mpg and am now down 2 about 22.1 I have noticed that when it gets cold I lose a mpg or two.

 

I'm down to around 17 from 24..I know why though, I start my car before I get in, with the heat blasting..Chicago weather is the best..

 

Its 22F outside here, and Im getting 21.xMPG (something or other)...., about 22mpg city. Thats mainly normal limited boost driving, beating the hell out of it from time to time, and boosting it WOT hitting a now 17-18psi with a 2.9" pulley....

 

That's a really good point because it does make a difference. I guess that brings up the question of what is the idea tire pressure?

 

Mine dropped from 32-33 to 30-31....Not bad but i do mainly highway driving so I was hoping to continuously get 34-36.
