That's a sharp truck. I've always been fan of GMC over Chevy.
On my Sierra the E85 break even point in fuel economy is a $1.20
Meaning it costs the same per mile to drive if gas was $4 and E85 is $2.80 Around here E85 was about $1 less than gas so it was costing me more to run on E85.
If I baby my'07 Z71 Crew Cab I get 15.5 MPG.
