I like your detailed mileage log - have you tracked oil consumption as well?

I have a little over 1,200 miles now and I am getting 14-15mpg commuting to work. It is about 15 miles each way with about 1/2 stop and go and part 45-55mph. I tried a couple of tanks of mid-grade Chevron with no (apparent) ill effects on performance, but not increase in fuel economy - but it did cost a little less to fill up.
 
Mine is a 6mt w/GT.

After 12000 miles of commuting to and from work I finally took a 1000 mile road trip. I drove up to san francisco using 5th gear as my final one.On this segment I averaged 19-20mpg. Very little difference from what I get commuting[18-19mpg].But I got stuck in LA traffic some.For the return trip I used 6th gear as the final drive--here I averaged 20-21.5mpg. Not much difference considering this segment is with the wind.

Paddle shifting vs. Full Auto on the RX-8 AT 4 sp. by trispec

After 3500 miles it appears the Paddle shifting vs Full Auto about 10% less efficient, but the 10% loss probably is because I keep the RPMs between 2500 and 3500 when Paddling. Full Auto constantly seeks to drop the RPMs to the minimum 1600 RPM.
 
Paddling vs Full Auto on the fun level depends. Having to watch the RPMs to shift can get tiresome in stop and go traffic, but if the road is clear, Paddle shifting is the only way to drive.
