Not for your specific car, but almost every car I've ever driven (gasoline) gets its best fuel economy at the lowest engine RPM you can reasonably drive in top gear. That's a good rule of thumb to follow.

For many examples, see:

Thread: Speed vs. MPG charts (post 'em if you got 'em)

Also, I second the recommendation of picking up some additional MPG instrumentation. You ideally want to see both instantaneous and trip average.

Another thing to pursue: if your automatic transmission has a "manual" mode, you can probably request earlier upshifts than the default "D" mode, and get into higher (fuel-saving) gears sooner.

EG., related topic:

Thread: "Short-shifting" a Jeep Patriot & Audi A4 CVT (forcing early "upshift") saves gas

And... belated welcome to the forum!
