6 banger mileage?

We just went to Long Beach, Washington and back last weekend, the 70 Duster we bought for my wife has a rebuilt slant with 26,000 miles on it, stock other than that.

Before we left I bought a brand new 1920 from Slant Six Dan.

Not sure how big the tank is, but Google says its 190 miles one way. I started with a hair over a half, and went from Lynnwood to Montesano and filled it at a hair over 1/4, that was 115 miles at 65-70 mph.

On the way back, I filled it in South Bend, and made it home with a little over a half tank, that seemed pretty good mileage to me.
