I really want to actually measure my FE, instead of this guesswork.
Well, you could always buy a ScanGauge and plug it into whichever vehicle you're driving at the moment. Since it calculates "current" MPG as well as "per trip" you could even leave it in all the time and still separate out your economy from the average that comes from both you and your mom driving it. Might be a little pricey if the only thing you get from it is MPGs, though.
By the way, I neglected to welcome you aboard before. Great first post!
It's $150. Not for a long time, man. I'll just reset the trip meter whenever I fill gas or something, it'll do. Also, my mother does most of the driving anyway, so I really cannot justify buying it. I get about 21% improvement on my dad's car, I'm sure it's not too different with the van.

Yep. Ya gotta do what you can. $150 when you're only driving a small amount and don't have your own car - I'd probably postpone the Scangauge for later too.
Unless maybe you can convince your parents it would be a good purchase for the family. Of course then it's not yours. But they would recoup the investment and learn a lot about FE driving in the process. Probably figure on a 15-20% improvement in FE from using the Scangauge, from there you can do the math. You get your money back over the next approx. $800-1000 you spend on gas.
Currently getting +/- 50 mpg in fall weather. EPA is 31/39 so not too shabby. WAI, fuel cutoff switch, full belly pan, smooth wheel covers.
