RE: Gas Mileage w/AT
My '90 Westy, at 5,000 lbs at the scale, 113,000 miles on it,
consistently gets 18-19+ on the highway.  I normally cruise at 55-65
mph.  In town stop-and-go driving I drop to around 14 mpg.  I've had one
200+ mile run that ran 22+ mpg and I've never figured out how that
happened, the same trip later was back to 18 mpg.  My '85 Westy used to
give me 22-24 mpg but that was a four speed.
