I always suggest people start with a more controlled test. That is: Get out on a straight flat road without any stops that goes for a least a few miles (This may not be easy depending on your area). Get up to a steady 55mph and set cruise control. Reset the trip2 MPG meter and wait for several miles. It should climb the the upper 30's to roughly 38-39 MPG. If you cant get this, there may be something wrong with the car (bad bearing, dragging break pad, engine computer out of whack.)
Edit: I was not very familiar with Costa Rica so I pulled up a terrain map. Wow, pretty much your whole country is mountains and hills. Nice on the eyes but hell on MPG.
i'm going to test it on weekend to see how many mile i can get on 55mph... my focus already have 5500kms so i believe break in is done
