2014 Chevrolet Silverado: Fuel Economy Update for August

September 5, 2013

2014 Chevrolet Silverado

It looks like our 2014 Chevrolet Silverado 1500 long-term test vehicle is destined for lots of use. We've only had it 6 weeks and the 5,000-mile mark is already out of sight in our rear-view mirror.

Our best tank so far has been 21 mpg over a very long haul that lasted 469.2 miles. Our rear-wheel drive Silverado is supposedly good for 23 mpg on the open road, which makes 500 miles a real possibility if our bladders can stand it.

But EPA combined is a much better gauge of what we can hope for once all the miles are mashed together, of what this thing does day-in, day-out. On that score we've averaged 17.6 mpg, a bit short of our two-wheel drive Silverado's 19-mpg combined rating. But we're within shouting distance.

Put another way, our truck is going through 5.7 gallons every 100 miles to this point instead of the rated 5.3 gallons per 100 miles.

We have 11 months to see if we can edge our Silverado closer to its EPA combined fuel consumption rating.

Worst Fill MPG: 12.5
Best Fill MPG: 21.0
Average Lifetime MPG: 17.6 (5.7 gallons per 100 miles)
EPA MPG Rating: 19 Combined (16 City / 23 Highway)
Best Range: 469.2 miles
Current Odometer: 5,146

    If you guys are using the truck like a truck by frequently having stuff loaded into the bed & tooling down the highways & byways like you say you are, then I wouldn't expect much improvement. But, good luck nonetheless.
