Well, I never put my A/C on in my car today, but today hit 100 and there was no way. So i put it on and i got about 13 mpg city, usually i get 18. Does anyone else with an SS get this low or is it just me?

07 SS

:D lol, sorry, but that's kind of funny. Sounds like you need to check your RPMs, I have an 03 3.8 and I keep ir at 2500 RPM when accelerating from a stop, 2k just accelerating, 1500-1750-ish cruising. I get 24 MPG, so try that.

I have an '08 SS with 51K on the odo, with my lead foot and A/C anytime the sun is out I average around 17.6-18.5.

It depends on what speed I'm cruising at on the highway. About 70mph, I see about 25mpg, cruising at 75-80mph it drops to about 23mpg.

My average is it 20.5 right now. 80% highway speeds (75+), 20% in town. Also, have stopped trying to 'baby it' for better MPG. Doesn't make a huge difference, so I drive it a little more aggressively. It's more fun that way! :eek:k3:

2007 ImpalaSS, Ram Air intake, Magna Flow mufflers.
On Cruise Control @ 65mph, 27-33.8 mpg!
The 33.8 was from Phoenix Az to La @ 65mph.
