The GMC Sierra shares its powertrain and oil life monitoring system with the Chevy Silverado since both trucks are built on the same platform. The reset procedure is identical, using the DIC controls on K2 models and the infotainment screen on T1 models. Sierra owners search specifically for their vehicle rather than looking at Silverado instructions, so here’s the exact process tailored to the Sierra’s menu structure and button layout.
T1 Sierra (2019+): Infotainment Method
Turn the ignition to ON or start the engine. On the infotainment touchscreen, navigate to Settings > Vehicle > Oil Life. Select “Reset” and confirm when prompted. The oil life display returns to 100%. The system remembers the reset even after you turn the truck off.
You can also reset through the instrument cluster using the steering wheel DIC controls. Press the scroll buttons to navigate to the Oil Life screen, then press and hold the checkmark button until the display resets to 100%. Both methods achieve the same result; use whichever is more convenient.
K2 Sierra (2014-2018): DIC Button Method
Turn the ignition to ON without starting the engine. Use the DIC button (located on the turn signal stalk or steering wheel, depending on trim level) to scroll through the instrument cluster displays until you reach “OIL LIFE REMAINING.” Press and hold the SET/RESET or checkmark button for approximately 5 seconds until the display flashes and resets to 100%. Turn the ignition off and restart to verify the reset was successful.
Dexos1 Oil Requirement
All 2011+ GM trucks, including every Sierra model, require Dexos1-certified oil. This is a warranty requirement, not a recommendation. The Dexos1 specification ensures the oil meets GM’s standards for engine protection, fuel efficiency, and emissions system compatibility. Using non-Dexos oil can provide grounds for a warranty claim denial if an oil-related failure occurs.
The correct viscosity depends on your engine: the 6.2L V8 typically uses 0W-20. The 5.3L V8 uses 0W-20 on 2019+ models and 5W-30 on earlier years. The 2.7L turbo uses 0W-20. The 3.0L Duramax diesel uses 0W-20. Check the oil cap for your specific engine’s requirement, and look for the Dexos logo on the oil bottle when purchasing.
ACDelco oil filters are GM’s OEM brand and provide correct fitment, bypass valve pressure, and filtering media for all Sierra engines. Quality aftermarket filters from Wix, Purolator, and Fram work equally well when matched to the correct part number for your engine.

Frequently Asked Questions
Is the Sierra’s oil life system the same as the Silverado’s?
Yes. Both trucks use GM’s Oil Life System with the same algorithm, the same monitoring parameters, and the same reset procedure. The only potential difference is the specific infotainment menu navigation, which varies slightly by trim level and screen size.
Can I use non-Dexos oil in the Sierra?
GM’s warranty requires Dexos1-certified oil. Using non-Dexos oil could provide grounds for a warranty claim denial. Fortunately, most major oil brands (Mobil 1, Valvoline, Pennzoil, Castrol, and others) offer Dexos1-certified versions of their popular formulas. Look for the Dexos logo on the bottle.
Why does my oil life drop faster in winter?
GM’s algorithm accounts for cold starts, extended idle time, and short trips, all of which degrade oil faster than warm-weather highway driving. In cold climates, these conditions are more frequent during winter, causing the oil life to decrease more quickly. This is the system working correctly, not a malfunction.
Does proper maintenance improve fuel economy on the Sierra?
Regular oil changes with the correct Dexos1 oil help maintain optimal engine efficiency. Combined with other maintenance practices, you can potentially improve your Sierra’s fuel economy.
