Practical maintenance tips
To keep oil levels accurate and the engine protected, follow these practical steps and checks.
Checking oil level and performing a top-up
Warm up the engine, then park on level ground. Remove the dipstick, wipe it clean, reinsert, and pull it out again to check the level. If low after an oil change, add small amounts of oil until the level reaches the full mark, then recheck. Always seal the drain plug securely and wipe up any spills.
Regular checks help prevent low-oil situations and protect the engine. For the exact interval and oil specification for your vehicle, refer to the owner's manual or a GM-certified technician.
