Fuel Milage

Don't laugh, the FC is better than the truck on milage.

However, I use fuel milage as a huge indicator for determining if something has gone wrong quick. The cold has killed milage (happens every year on all cars) and its down to about 14.7-15.5 mpg. This is mostly highway and some city mixed in. The question I have is, is that normal? I know edmunds lists 18 highway for NA's but 15?

Anything I can do to improve this (i know

me) but i have adjusted my driving style for rotary (keeping it above 2500 with any throttle over 5%) and do 3k oil changes, checking oil every other fill up (about every 6 days).
