Curious About Gas Mileage

Hi,

I'm am wondering what other people are averaging (from the computer's reading) for gas mileage...I'm wondering if I'm on par with the rest of you guys cause I'm getting about 15mpg average over the last 3 tankfulls of the same brand 91 octane doing combined city/hwy driving...non-agressive driving was being used to check mileage, no racing or anything...

Thanks in advance..

I come in more like 18, city and highway. Highway is in the mid 20's. I typically burn 89 octane.

I run Sunoco 94 and drive fairly aggressive, but since it's mostly highway my mileage doesn't suffer too bad. I average 18-20 during a normal week, 12-15 during a "city-driving" week, and 28-30 on long road trips

i get about 16mpg with Los Angeles traffic.
