27 MPG Was pleasantly surprised when I check my freeway mileage yesterday. I filled up and drove on a flat freeway for exactly 50 miles and filled again. It took exactly 1.8 gallons. 50÷1.8=27.7
I was using cruise control at an average of 71 mph. Was on I-84 from Hood Rover, Oregon to GreshamOregon.Speed?
These were my optimum speeds for mpg breaking in my B58. I found having multiple attendents at multiple stations pumping gas (reqired) in Oregon made my observed mpg impossible to accurately gauge. I wound up getting 17-18 over the 800 mile break in ride home which averaged 53 mph.Have seen 30mpg (diesel) on a trip at Scottisch Highlands and Lewis/Harris. Mostly small roads, 50-80km/h, sometimes 100km/h.
