Alright now I'm stumped

It looks like most of you are getting around 27 - 29 mpg on the highway.

How are you calculating this ? Are you using the OBC, or dividing gallons purchased into miles driven ?

Like I said, I was really suprised to only get 22 - 24 mpg on my trip.

My daily commute is 20 miles on local roads and for the last two years I consistently see 21 mpg on every fill up.

Was it due to my speed on this trip ( 80 - 85 mph ) ?

Top was up and AC on - did this make a difference ?

Was it the added weight ( two people plus front and back trunk packed ) ?

Was it the elevation changes ( from Illinois to Virginia ) ?

Any insite or suggestions would be appreciated..

Thanks,

Nick
