ok so i"m a little late to the party (story of my life!).
having owned a ng900 saab i can tell you from my personal experience that the SID (SAAB Information Display) on the dash takes quite a bit of time (and/or different driving style) to make a change in the mpg number.
I say great job even if you can't make it happen everyday.
***a side note about my experience with switching to synthetic fluids, I saw a 1.2 mpg increase in the MPG #'s after switching to synthetics (it took about a month to get there but it stayed there for the following 8 months i owned the car, so probably not a fluke.
