In the month of October, our long-term 2014 Chevrolet Silverado spun an additional 2,137 miles onto its odometer and consumed 124.5 gallons of 87-octane fuel. That equates to 17.2 miles per gallon for the month, which is just a hair less than its lifetime average of 17.3 mpg.

These results so far are less than the truck's EPA combined rating of 19 mpg.
