Not bad considering...
Today started out before daylight with pea soup fog. Not a fun way to start a long day. I got a bite of breakfast and started east slowly as the fog lifted. It was replaced with 20-30 mph winds from the northeast. A quartering headwind catches the largest profile of the car. Traffic was light and I continued with my target of 5 over the limit. (The Mk IV VW speedometer reads 2-3 mph higher than the Garmin on the dashboard). However, much of the day was spent at an actual 5 over the 75 mph limit through Nebraska and Iowa.
Between freezing drizzle on the windshield, wind and light snow at times, I still managed 46.2 mpg for the day at an average speed of 70 mph. Luckily as the day progressed it slowly warmed into the 40s and the wind slowed into the teens out of the north.
884 miles, 19.1 gallons used, 12.6 hours of driving.
