Capacity by engine option

Oil change interval

General Motors recommends using the vehicle's Oil Life Monitoring (OLM) system to determine oil change intervals. This system takes into account various factors such as engine revolutions, engine temperature, and driving conditions.

• Normal Duty: Typically, the OLM will recommend an oil change between 7,500 to 10,000 miles or 12 months, whichever comes first.
• Severe Duty: Under severe operating conditions (e.g., frequent short trips, extreme temperatures, towing, dusty environments), the OLM system may trigger an oil change as early as 3,000 miles.

Always adhere to the OLM system's recommendation and reset it after each oil change.

Drain plug torque

The oil drain plug torque specification for the 2018 Chevrolet Silverado 1500 is 18 lb-ft (24 Nm) for all engine options. It is highly recommended to replace the drain plug gasket or crush washer with a new one every time the oil is changed to ensure a proper seal and prevent leaks. Always use a torque wrench to prevent overtightening, which can strip the oil pan threads, or undertightening, which can lead to leaks.

How to change the oil

1. Safely lift and secure the front of the vehicle using a jack and jack stands.
2. Locate the oil drain plug on the oil pan, typically at the bottom rear of the engine.
3. Place a suitable drain pan underneath the drain plug.
4. Remove the drain plug with a wrench and allow all the old oil to drain completely.
5. Once the oil has drained, clean the drain plug and install a new crush washer. Reinstall the drain plug and tighten it to 18 lb-ft (24 Nm).
6. Locate the oil filter, typically on the side of the engine block for V8s or closer to the front for the V6.
7. Place the drain pan under the filter to catch any residual oil.
8. Remove the old oil filter using an oil filter wrench.
9. Apply a thin film of new oil to the gasket of the new oil filter.
10. Hand-tighten the new oil filter until the gasket makes contact, then turn an additional 3/4 to 1 full turn. Consult filter instructions for exact turns.
11. Lower the vehicle.
12. Remove the oil cap on top of the engine.
13. Carefully add the recommended amount and type of new oil (refer to engine specifics in the "Capacity by engine option" table).
14. Reinstall the oil cap.
15. Start the engine and let it run for a few minutes to circulate the new oil. Check for any leaks around the drain plug and oil filter.
16. Shut off the engine, wait a few minutes, and then check the oil level on the dipstick. Top off if necessary.
17. Reset the Oil Life Monitoring (OLM) system.

Common issues / tips

• Active Fuel Management (AFM)/Dynamic Fuel Management (DFM): The 2018 Silverado 1500 V8 engines, particularly the 5.3L and 6.2L, are equipped with AFM (also known as cylinder deactivation). This system can be sensitive to oil quality and level. Using the correct Dexos1 Gen2 specification oil and maintaining proper oil levels is crucial to prevent potential lifter issues or excessive oil consumption. Some owners report that using a quality full synthetic oil and regular changes can help mitigate some AFM-related concerns.
• Oil Consumption: Some 2018 Silverado 1500s, especially those with AFM, may exhibit higher than normal oil consumption. Regularly checking your oil level between changes is highly recommended.
• Consult Your Owner's Manual: While this guide provides comprehensive information, always refer to your vehicle's owner's manual for the most accurate and up-to-date specifications for your particular trim level and engine.
