Dude,

Your friend has too much time on their hands to be tracking gas mileage/expenses so closely; however, since they did...

My 06 S2K has 7600 miles on it, and I aveage about 25.2 mpg during mostly highway driving at about 75mph to/from work.

Back in June I received 30.2 mpg on one tank during an all highway roadtrip to SAC2K Days; my low was 23.0 mpg doing a combination of city/highway driving.

I didn't buy the S2K because of economy, but next to performance it has been a nice bonus.

 

Actually, I don't know him. He just PMd me out of the blue to ask me to do this for him. I don't know why he picked me, but I thought I'd do it anyway.

As for too much time on his hands, you would be surprised how many people do this sort of thing as a normal course of day to day car ownership.

 

xviper, thanks for posting up the graphs. Maybe your friend should get together with i_heart_my_DB8 (since they are both in Southern Cal) because i_heart_my_DB8 also seems to be a Statistics Geek regarding his S2k (but he probably picked up that bad habit from someone else).

Yes, too much time on my hands, but I'm a retired engineer with a penchant for detail - what do you expect? AP1 from new, mostly local suburban/freeway driving with a few 400-mile trips and one track day.
