Capacity by Engine Option

Always consult your owner's manual for the most accurate and up-to-date information, as specifications can sometimes vary or be updated by the manufacturer.

Oil Change Interval

For the 2023 GMC Sierra 1500, the oil change interval is primarily dictated by the vehicle's Oil Life Monitoring (OLM) system. This system takes into account various factors such as engine RPMs, temperature, trip length, and load to determine the optimal time for an oil change.

• Normal Duty: Follow the Oil Life Monitoring (OLM) system, typically indicating an oil change between 7,500 to 10,000 miles or 12 months, whichever comes first. The OLM will usually alert you when the oil life reaches below 15-20%.
• Severe Duty: If you frequently operate your Sierra under severe conditions, the OLM will adjust accordingly, but a general guideline for severe duty is to change your oil every 3,000 to 5,000 miles or 6 months. Severe conditions include:
  • Frequent short trips (less than 5-10 miles)
  • Operating in extremely hot or cold temperatures
  • Heavy towing or hauling
  • Driving in dusty or muddy conditions
  • Extensive idling

It's always best to reset your OLM system after every oil change to ensure accurate monitoring.

Drain Plug Torque

Proper drain plug torque is crucial to prevent leaks and avoid damaging the oil pan threads. Always use a torque wrench.

• 2.7L Turbo (L3B): 18 lb-ft (25 Nm)
• 5.3L EcoTec3 V8 (L84/L8M) & 6.2L EcoTec3 V8 (L87): 18 lb-ft (25 Nm)
• 3.0L Duramax Turbo-Diesel (LM2/LZ0): 20 lb-ft (27 Nm)

Most modern vehicles, including the Sierra 1500, use a single-use crush washer or a sealing gasket on the drain plug. Always replace this crush washer with a new one during every oil change to ensure a proper seal and prevent leaks. Failure to do so is a common cause of drips.

How to Change the Oil (General Steps)

Changing the oil in your 2023 GMC Sierra 1500 is a straightforward process for the DIY enthusiast. Always prioritize safety first.

1. Gather Supplies: New oil, new oil filter, new crush washer, drain pan, funnels, rags, socket/wrench for the drain plug, oil filter wrench (if needed), jack, jack stands, and wheel chocks.
2. Warm Up Engine (Slightly): Run the engine for a few minutes to bring the oil to operating temperature. Warm oil flows better and helps suspended contaminants drain out.
3. Lift and Secure Vehicle: Safely lift the front of the truck using a jack and secure it with jack stands. Chock the rear wheels. Ensure the vehicle is stable and level.
4. Locate Drain Plug and Pan: Place the drain pan directly beneath the oil pan drain plug. Use the correct size socket or wrench to loosen and remove the drain plug. Be prepared for the oil to come out quickly and hot.
5. Drain Oil: Allow all the old oil to drain completely into the pan. This usually takes 10-15 minutes.
6. Replace Drain Plug: Once drained, clean the drain plug and install a NEW crush washer. Reinstall the drain plug and torque it to the specified setting (see above).
7. Remove Old Oil Filter: Place the drain pan under the oil filter. Use an oil filter wrench if necessary to loosen and remove the old filter. Some residual oil will drain out.
8. Prepare New Oil Filter: Apply a thin film of new engine oil to the gasket of the new oil filter. This helps create a better seal.
9. Install New Oil Filter: Hand-tighten the new oil filter until the gasket seats correctly, then tighten an additional 3/4 to 1 full turn. Do not overtighten.
10. Add New Oil: Using a funnel, carefully add the recommended amount and type of new engine oil through the oil fill cap on the engine.
11. Check Oil Level: After adding the oil, start the engine and let it run for a minute to circulate the new oil. Turn off the engine, wait a few minutes for the oil to settle, and then check the oil level using the dipstick. Add more oil if necessary, but avoid overfilling.
12. Inspect for Leaks: Visually inspect the drain plug and oil filter for any signs of leaks.
13. Lower Vehicle & Reset OLM: Safely lower the vehicle to the ground. Reset your Oil Life Monitoring system according to your owner's manual instructions.

Common Issues / Tips for this Generation (2019-Present)

• Active Fuel Management (AFM)/Dynamic Fuel Management (DFM): The GM 5.3L and 6.2L V8 engines with AFM/DFM can be sensitive to oil quality and level. Using the specified Dexos1 Gen3 oil and maintaining the correct oil level is crucial to prevent lifter issues and excessive oil consumption. Some owners report higher oil consumption with these engines; regular oil level checks are highly recommended.
• 2.7L Turbo Oil Filter Housing: The 2.7L Turbo engine uses a cartridge-style oil filter, which is housed in a plastic cap. Be careful not to overtighten the cap, and ensure the O-rings are correctly seated when replacing the filter to prevent leaks.
• 3.0L Duramax Oil Specification: The Duramax diesel engine requires Dexos D specific oil, which is a low-ash formulation designed for diesel engines with modern emissions systems. Do not use gasoline engine oil in the diesel.
• Oil Life Monitor (OLM): While generally accurate, if you notice your OLM suggesting very long intervals, consider a slightly shorter interval, especially if your driving habits lean towards severe duty, even if the OLM doesn't categorize it as such.
• Underbody Protection: Depending on the trim level and options, your Sierra might have extensive underbody shields that need to be removed to access the drain plug and oil filter. Be aware of the fasteners and their locations.
