In article <38ED44F4.DCC7B957nopsamcom>, mweinopsamcom says... Although your statements about more air means more gas used makes sense, actual experience doesn't bear it out. I have three turbo SAABS and they get INCREDIBLE mileage (none have less than 110K mi on them). I have gotten 33mpg at 70 and 29mpg cruising at 90. Perhaps SAAB has a much better efficiency in their APC system, but the mileage is something I couldn't believe until I saw it.
