tiffinboy......You originally asked if we thought your friend could get the mileage he was claiming. Several came on here, said he couldn't and explained why. Others told you what they were getting and how they achieved those numbers, but you have criticized or made fun of almost every response. Either you're a Troll or have the need to argue everything.
You state that you drive from Reno to Bishop and get no where near what others are getting....duh! If I drove back and forth over the Grapvine ten times and no where else, I would probably only see 3-5 mpg.
If you're goal is to argue or criticize every answer you get after asking a question, maybe you should find something else to do.
