i had one of those "motor minder" vacuum gauges in a 68 mustang back in the early 80's and the way to get high vac was to be very gingerly on the pedal. it was interesting to see how sensitive vac was in relation to the pedal... peter That's true. I've noted the same in the Subaru, but at cruising speed it's easy to maintain higher vac. Once you overcome rolling resistance and hit cruising speed, the vac increases and the MPG goes up. I've found that my MPG goes DOWN in conditions where I'm cruising along and then have to decrease speed, as when one encounters someone who's driving quite slowly. The vac goes down, rolling resistance increases, and if slow enough, the engine either lugs or the trans has to drop to a lower gear. There's a lot of misinformation regarding MPG, but there are many different vehicles, and not every idea will apply to every vehicle. Gauges/meters tell you what works. **************Vote for your city's best dining and nightlife. City's Best 2008. (http://citysbest.aol.com?ncid=aolacg00050000000102)
