I'm probably lucky to see 15 - 16mpg, but it sure is a ton of fun.

Although, I'm coming from an E63 which was not economical in the slightest (12 - 14mpg), a V8 S4 (18mpg) prior to that, and my current "econobox" STi commuter gets 18 - 19mpg, which surprised me honestly. I can't even fathom what 30mpg would be like. Whatever, it is what it is. :-)

Hmm, after reading the above, I'm starting to think that there must be something wrong with my right foot. ;-)

 

I drove mine to the 1/2 mile roll races on a full tank(1hr or so), did 19 passes, drove back. Avg mpg for the tank was 18. avg 80 on way out. Stock, Tip.
