I got 25-27mpg on a 1200+ mile trip from Boise to Bay Area and back for
Thanksgiving, mostly law-abiding or +5ish on the freeway, some blasts around
traffic on the OR 55mph 2-lanes. Snow storm backed up traffic from Donner
into Reno on the way back, that didn't help mileage much - I had Hakkas on
already so could have gone faster than most CA BMWipers clogging the road.
My sedan has a Hoppen chip w/2.5Bar sensor. Plug wires, plugs, thermostat
several years old; most other engine components are original.

seems :(

it's been stolen (but what fun is that?)
