just put 300 highway miles on my Q this weekend. filled up fri. night then drove to philly. yesterday, with about 1/2 tank, received my order of bg44k. put in tank and drove around 160 HARD highway miles. lots, and lots of WOT runs. just filled up, took 16 gallons with an average of 18.6 MPG!!! i was regularly getting anywhere from 10 to 14, mostly short trips though. the Q really needs the highway to stretch the gas. i'm also working with old O2 sensors and KS'ers that will be changed soon with the plenum job. the MPG should improve even more with the new ones,,,,,i hope!!!! WHAT A HIGHWAY MONSTER!!!!! CAN'T WAIT TO TURN HER LOOSE AGAIN!!!! :D JEFF
