Both times I filled the tank, I did not attempt to fill beyond the first auto-shuttoff of the pump. I divided the number of gallons put in into the number of miles I travelled. I triple-checked my math. I didn't believe it either, but there it was. I was hauling, maybe 800 pounds in the back.

I have had 3 astro/safari vans for about 10 years. Driven highway behind trucks to reduce wind at 45, 50, 60, 70, and many other speeds for many miles and many years. I have never reached better than 20 mpg.
