Maybe all these 12mpg GMCs are driving around in the Midwest on
dead-flat roads? We do have freeways that go up and down some here in
the Pacific NW.

Hopefully it's just guys bragging because they want to think they're
getting great mileage. FWIW, I see the same thing with the Datsun
crowd. Never saw more than 28mpg with any of my original-motored
Datsuns. Other guys swear they've seen 35mpg at 70mph. Ain't. Never.
Happened.

Right on Kelvin back in the day I had a friend that swore his 22 ft Kayot motor home got an honest 13 miles to the gallon. Well some time later my brother bought that 318 powered motor home and was he surprised when the actual mileage turned out to be 5 miles to the gallon.We wound up replacing the 2 barrel carburetor and manifold with a modified AFB four barrel and manifold as a rebuild on the 2 barrel was of no help. the 4 barrel increased it to 7 miles to the gallon. I have friends that tell me of big cars that get better mileage then my little Rav 4. When I check the manufactures estimated freeway MPG on those big cars it is 5-10 less? How can that be unless they are lying.
