Re: Chicago MPG's
Chicago's blended fuel is best used for paint thinner; it is pathetic. On Windy City area fuels fill ups, I've been getting at WORST 14mpg in lost of rush hour crawling along clogged arterial roads with the AC on. A 4cyl Audi I once had did about 18mpg in the same condition, so no worries. If I have Wisconin-purchased fuel, it is 16-17mpg under the same conditions. On the highway I distinctly notice a nearly 4mpg drop in highway fuel economy versus when filling up in Wisconsin (20.5mpg vs 24mpg) in the summer with AC on and typical 60-65mph highway speeds. Either way, the Hemi is exceedingly good on fuel given what it is: full-time 4WD, big V8, 5000+ lb SUV. As a side note, the "special" blend of fuel required for the Chicago area is why we pay $.80/gal more than the rest of the country for gasoline and for questionable benefit.
An expert is one who knows more and more about less and less until he knows absolutely everything about nothing.
