i just bought that exact same car!! lol it has the 5-spd tiptronic auto tranny. with that, i get on average (mind you i have a leadfoot

) 15-17mpg mainly city driving. It takes minimum 91 octane

the car has been a frickin blast to drive, speaking since i used to own a 90 eclipse gsx. The awd system is phenomenal and the car is waay torquey. it handles like a dream and has good brakes. The oil it recommends is 5w-40 full synthetic w/8qts....ie: i spent $104 on my first oil change. I have a few minor issues with the 6-disc changer in the back and the sensor/controller thingy for the thermostat housing (electric thermostat) is going a little a-wall and it slightly overheats but never above 200f. overall....I LOVE IT! It's a fun car to drive.
***I got it back in january in the heart of winter here in utah.....it handled sooo well in the snow. the only drawback was if i gave it any more than just a little gas, the torque kicked in like no other and i kinda slid sideways, but that only happened a few times when i really romped on the throttle. other than that, i climbed up steep hills that were very snowy and icy with no problems.
