So, with nothing better to do on I 81 for 300 miles today, I figured I might as well see what gas mileage I'm getting. Staying at around 75 -80 I averaged 32 mpg. At the (ahem) speed limit it would probably be closer to 35 mpg.
I guess at close to 130 degrees in the 'office' your mind turns to such mundane things...
Hope everyone got home safe.
Steve.
