Capacity by engine option

Oil change interval

• Normal Duty: The Engine Oil Life System should be monitored. Under normal driving conditions, the system can recommend oil changes up to 7,500 miles or 12 months, whichever comes first. However, many technicians and enthusiasts recommend more frequent changes for optimal engine longevity.
• Severe Duty: If your driving involves frequent short trips, extensive idling, towing, or dusty conditions, the oil change interval will be shorter, and the Engine Oil Life System will reflect this. Consider changing the oil every 3,000-5,000 miles or 6 months.

Drain plug torque

The oil drain plug on the 2015 GMC Sierra 1500 should be torqued to 18 lb-ft (24 Nm). Always use a new drain plug crush washer to ensure a proper seal and prevent leaks. Most new oil filters come with a new crush washer.

How to change the oil

1. Warm up the engine: Drive the vehicle for a few minutes to bring the oil up to operating temperature, ensuring it drains more easily.
2. Lift and secure: Safely lift the front of the truck using a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.
3. Locate drain plug: Place a suitable oil drain pan under the oil pan, then carefully remove the drain plug with the correct wrench. Allow the old oil to drain completely.
4. Replace filter: Once the oil has drained, remove the old oil filter. Apply a thin film of new oil to the gasket of the new filter before threading it on. Hand-tighten the new filter until snug, then give it an additional 3/4 to 1 full turn (or as per filter manufacturer's instructions).
5. Reinstall drain plug: Install the new crush washer on the drain plug and reinsert it into the oil pan. Torque to 18 lb-ft (24 Nm).
6. Refill with oil: Lower the vehicle. Locate the oil fill cap on the engine and add the recommended amount and type of fresh engine oil.
7. Check level: Start the engine and let it run for a minute to circulate the new oil. Turn off the engine, wait a few minutes, then check the oil level with the dipstick. Top off if necessary.
8. Reset oil life monitor: Consult your owner's manual for the specific procedure to reset the oil life monitor on your 2015 Sierra 1500.

Common issues / tips

• Active Fuel Management (AFM) / Dynamic Fuel Management (DFM): The 5.3L and 6.2L EcoTec3 V8 engines in the 2015 Sierra utilize AFM/DFM technology, which can be sensitive to oil quality and level. Using Dexos-approved oil and maintaining proper oil levels is crucial to prevent potential lifter issues or excessive oil consumption.
• Oil Consumption: Some owners report oil consumption, particularly with the 5.3L engine. Regularly check your oil level between changes and top off as needed. Using a full synthetic Dexos-approved oil may help.
• Oil Pressure Sensor: The oil pressure sensor can sometimes fail, leading to inaccurate readings or warning lights. If you suspect an issue, have it diagnosed by a qualified technician.
• Proper Disposal: Always dispose of used engine oil and filters responsibly at an authorized recycling center.
