2014 Acura MDX: Oregon Road Trip MPG

July 29, 2014

2014 Acura MDX

This trip to Oregon in our long-term 2014 Acura MDX AWD wasn't a vacation, really. My eldest daughter is heading off to college this fall, and she needed to attend a two-day introDUCKtion program to meet her advisor, sign up for classes and see how much space she'll have in her dorm room at the University of Oregon.

I'll share a few new observations I made during the drive in a couple of posts to come, but the thing that really stuck out was the range and fuel economy. We managed to wring 541 miles out of one tank at 29.9 mpg. Not bad at all considering its 27-mpg highway rating.

The meter read 31.5 mpg when I finally stopped for fuel, and that 1.6-mpg overstatement represents a 5-percent error in Acura's favor.

That was typical on this trip. The meter consistently boasted of better mpg than was actually delivered, and the exaggeration ranged between 4 and 7 percent at the trip's six fuel stops.

It always frosts me when meters read consistently high. Conspiracy theories start swirling around in my head. Always-high readings are certainly much better when it comes to customer satisfaction. I know these meters aren't perfect, but I'd feel better if they dithered between too high and too low and came to some sort of consensus with reality.

Still, the real number on this tank is pretty impressive. It came about through strict use of cruise control at 65 mph, but the result most certainly would have topped 30 mpg if not for three or four exits for food stops and restroom breaks.

The entire trip was 2,374 miles in length, and that included some in-town miles in Eugene and a couple of solo forays up into the mountains to hiking trailheads while my daughter was at school. All in, the MDX averaged 25.5 mpg over that distance. The official fuel economy rating is 21 mpg combined (18 city/27 highway).
