2015 Ford F-150: Big Month for Miles Moves Fuel Economy Up a Hair

by Jason Kavanagh, Engineering Editor on November 4, 2015

2015 Ford F-150

October was a busy month for our long-term 2015 Ford F-150. It covered 5,255 miles — its largest monthly mile total to date — and received an, ah, enlightening oil change along the way.

In October our F-150 achieved 18.0 mpg. This is its second-highest monthly mpg we've observed since it was new in January. Despite October being a freeway-heavy month, we're still seeing fuel economy far short of the F-150's EPA combined rating of 20 mpg. Nevertheless, it was a strong enough month to move our truck's lifetime average up by 0.2 mpg to 16.9 mpg.

There are some ruminations that our truck's overfilled crankcase could have been eating into its fuel economy. That's certainly possible and it's the first thing that crossed our minds when we discovered that four extra quarts of oil had been poured in at its last oil change.

Early indications suggest that correcting the oil mishap still may not bring our truck's as-tested fuel economy in line with its window sticker, though it's still early. Stay tuned.
