Who is BS'ing who?

I built a 68 Barracuda back in college and drove it between school and home and averaged 17.75 MPG on the highway checking it more than three times.

318 block, 340 cam, 360 1.88 heads, rhoades lifters, dual plane cast iron intake, Holley 600 vacuum secondaries, 7 1/4 axle with 2.76 gears, with stock exhaust manifolds and dual exhaust. Idled at 22 1/2" of mercury, I installed a 10.5 power valve and had a vacuum guage and could part throttle accelerate nicely and gently above 12" mercury. I would fill the tank up before getting on the highway and then stop for gas after 200 miles and check the economy.

After breaking three 7 1/4" axles, I switched to an 8 3/4 3.23 and got around 16 1/2 MPG. But that 3.23 sure grip with the narrow tires really went through snow great. Was worth the drop in economy for the better traction in snow.
