Well me my fiance', and my son all went down to seminole fl on tuesday well midnight on monday and heres what i ended up with. 256 miles @ 65-85mph with a/c set on 72 degrees only used half a tank of gas! thats 32 mpg. I think alot of it has to do with the absolute absence of any traffic whatsoever and it was 75 degrees that night compared to the usual 90s during the day. but i was quite pleased. Just thought i'd share.
