Ok folks latest news on Frank Bethel's '06 Chevy Avalanche...He took a 164 mile trip this last weekend to Virginia City Nev. and to Fallon and back to Reno. IT's a steep twisty mountain road to VC. Before the Groove, the Av returned 11.3 MPG on both computer and miles/gallons on paper. Frank drove 164 miles, used 9.5 gallons--thats 17.26 MPG on this trip!!
That is over Fifty Percent Increase folks, and a mountain road to boot!!! (Computer only says 12.3 MPG, Similar to what TacomaKarl reported for his Avalanche). I trust actual miles/gallons used more.
Frank and his wife will be taking a long vacation in the Avalanche in a week, and will log his miles and gallons so I should have a better model to report later!! TracyG
