First measured tank...18 MPG!
 

Okay, I know it doesn't like a lot, but that's 20% over EPA combined. Truck is bone-stock at the moment (though I have a plan or two for aero mods).

Roughly +3 MPG from hypermiling (mostly EOC and trying to time lights).

A bit more impressive when you consider this isn't a "lifestyle vehicle": it's a money-earner that spends a fair amount of time configured like this:

Figure on getting 1 to 2 additional MPG from DWL and DWG.

Consider getting a Scan Gauge II.

I have a SG, but.I thought they only worked on OBDII vehicles. My truck's a '94.

If there's a way to get it to play nice with a '94, heck yeah!
