GMC Sierra Gas Mileage

December 3rd, 2007 | GMC, diesel, trucks

Like the full-size Chevrolet Silverado pickup, but want something a little different? Take a look at the Sierra, GMC’s stable mate for the Silverado. The half-ton GMC Sierra 1500 offers respectable gas mileage for a full size pickup when fitted with the base 4.6 liter six cylinder engine. When coupled with a five-speed manual transmission in a 2WD Sierra, the 4.6 liter six provides 15 city and 20 highway miles per gallon.

GMC Canyon Engine Options
GMC offers a wide range of engine options in the half-ton Sierra 1500 range. Although GMC offers diesel engine options for the heavy-duty Sierra 2500HD and 3500HD, the Sierra 1500 choices are gas-only.

  • Vortec 4.3 liter V6
  • Vortec 4.8 liter V8
  • Vortec 5.3 liter V8 (iron-block, Active Fuel Management, with or without FlexFuel)
  • Vortec 5.3 liter V8 (aluminum-block, Active Fuel Management, with or without FlexFuel)
  • Vortec MAX 6.0 liter V8 (Active Fuel Management)

The 2500HD and 3500HD come standard with the Vortec 6.0 liter V8, with the Duramax Diesel 6.6 liter turbo V8 available as an option. GMC does not publish mileage ratings for the Duramax diesels, which are produced by a joint venture between GM and Isuzu.
