But I haven't been keeping track for about 1 1/2 years now.

Is that how you are calculating mpg's? Or are you using a tool that gives constant updates to your mpg? Like 127.0.0.1 said about getting 348 rolling down the driveway, but if you were driving up a hill it would display something much lower... like 20 something or maybe. Cause I know my sisters Envoy has all that fancy computer stuff measuring all that for her and I can get it to display 80+ under the right conditions. But I can also get it to display 6.

Exactly! I average about 33-36 driving very easy and rarely use a/c, mostly highway driving at 60mph. I question the techniques of some of the people who go 75 mph+ with a/c going that claim 40+ mpg. I'm very specific about my recording technique and have been through Calculus II in college so I know my calculations. lol

I've not broken 32mpg in 2+ years of ownership.
I'm getting a steady 30 mpg and that's with A/C on everyday this summer.
The best I ever got on my '97 Saturn twin cam was about 28mpg on a 1.9L engine. It was a stick shift, BTW.
I guess the 5 speed makes a huge difference....

Ambient temperature plays a HUGE factor in fuel economy, I've noticed the 1NZ-FE is particularly sensitive to incoming air temperature, when it comes to overall fuel-economy.

My first check of mpg was on a 120 mile stretch of I94, going 74 mph using cruise control with the AC on. It was in the mid 80's outside. I write down the odometer reading when filling the tank. I got 39.6 mph. Tires had 32 psi.

In town I've gotten between 33.5-36 mpg.
