I can;t recall who it is but some old sage on this list when asked how many mpg you should get with a GMC always answers “8 to 10 mpg”. Over the dozen or so years we have had our coach he is right on. No matter what you use, a carb or FI, what distributor you have, headers or no headers, a a 23 or a 26, towing or not towing it always is between “8 to 10”.
