Ideally you'll have the add-a-gauge feature set up so you'll be able to watch both instant & averaged MPG on the same screen.
Speeds reasonable have largest effect. Being a retired aviator, I like to play the game of hitting my checkpoints on time using a proposed average mph. Setting the ScanGuage up w/instant & averaged MPG and Fuel Flow is really easy to drive.

I had trip yesterday back from Orlando (157 miles all Turnpike/Interstate). I set my checkpoint times (+/-5 min.), the set my "requested" mpg as frequently as I could to met my time requirements. I use to estimate route mileage, pre-trip. I chose 60mph as my proposed avg speed, and ended up averaging 58mph. I shot for 42.5mpg, and exceeded that with about 45% trip remaining. My Max Speed was 77mph, going downhill at .35gph behind a semi who I caught at the crest of the previous uphill. I tried to hang in the 1.5gpm range on flats which usally had me around 65mph. Ultimately, I arrived "around 3 minutes late" and at a SuperCool 45mpg FE averaging 1.268gph.
