Both the 4.8-liter and 5.3-liter V8 engines getS5.7 liters (6.0 quarts) of fluid with the same viscosity. GMC recommends changing the oil in this vehicle every 7,000 miles. However, this number is going to be much smaller, if You do a lot of towing, driving on dirt roads, or often have long commutes at low speeds. A few popular picks of 5W-30 products include Amsoil Signature series, Mobil 1, Pennzoil Ultra Platinum, Castrol Edge, Motorcraft, and Royal Purple. Always make sure the engine has cooled at least 5 minutes before checking or changing this fluid. The average cost of an oil change for the Sierra 1500 is $120 to $150. This price includes labor, so You can save a bit of money, if You replace it Yourself.
