2022 Silverado 1500 returning 21.7 mpg

[Christian P.]

I rented a Silverado 1500 for a quick trip from Reno to Half Moon Bay.

514 miles, took 23.7 gallons for an average of 21.7 mpg. This is a mix of highway, stuck in traffic, some city driving and a small payload of wood on the way back.

Given, this was the 2WD version with the base V8. I suspect the 4wd would loose 1 or 2mpg.

But still much better than I expected.

2010 Suburban 4WD with the 5.3. Wife regularly gets 16/17 mixed to work and back. We see 20s on the highway, fully loaded with gear and people. Closing in on 200k and still going strong. ?

One might even get a bit more with a truck cap that matches the cab dimensions and smooths the airflow over the truck bed.

Not at all unusual for that configuration to get mileage like that. Dad has a 2014 2WD double cab with the 5.3, and his lifetime average is over 20 mpg. That mileage from that size vehicle skews everything for me; 25 mpg from a 4 cylinder crossover or 30 from a compact car with less than half the HP are relatively unimpressive.

514 miles! Long way to go for a dump run…

So reg cab Long box with 5.3 and 8 speed?
What size tires, any idea?

I never managed to breach 20 mpg US with my 3.7 F150 Supercab 4x4, on 235/80R17 or 34x10.5 on pure highway runs doing 55-65 mph. I think 21+ is good for mixed driving!

Our stock Super Duty 4x4 could hit 19mpg empty on factory 33s - 6.2L. My 2016 Tundra 4x4 would hit 20mpg with stock diameter Ko2s. These trucks drop like a rock when you remove all the bumper air deflectors, add lift and any tire diameter or tread change. Ford Ecoboost is the same way and they sit lower to the ground than a minivan.

70,000 miles now on my F150 Supercab with the 3.5 Ecoboost engine. Lifetime average fuel mileage since I bought the truck new is 20.5 mpg, and that's calculated by an Excel spreadsheet, not reading the truck's display. Driven carefully it can give some fantastic mileage for a 5500 lb truck:


36 gallon tank - so I'd driven 507 miles since the last fillup, and still had 357 miles to go to empty.

But towing a heavy trailer behind it drops the mileage nearly in half:

According to Fuelly the Silverado with a 5.3 averages over 16 mpg, which is quite good for a V8: https://www.fuelly.com/car/chevrolet/silverado_1500?engineconfig_id=63&bodytype_id=&submodel_id=

Tundra with the 5.7 is a good 2mpg lower, with the new turbo engine being a bit better with a 16.75 avg. The F150 3.5EB or 5.0 are about the same as the Silverado.

I'm happy with my 2016 Tundra getting 17.5-18.0 mpg on freeway and mountain driving with 35x13 Hankook ATs and 2" front lift. It's as good as it was on the Bridgestone street tires, although I swapped at 5k miles and vehicles tend to get better as they break in.

I do wonder how much a high clearance bumper can mess up the aero... or bull bars. I still have stock.

I believe I have she same engine in our Ford Transit Ecoboost AWD. I can't get past 12.5 mpg.

2010 2500 silverado w/ 6.0L. 11mpg. 200k
2008 "" suburban "" "" 12mpg. 150k

The good news is I still get 9-10 mpg pulling an 8k+ lbs load
