1. Preparation

Ensure the engine is cool and parked on a level surface.
Gather necessary tools and parts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostics port.
Record any error codes and interpret their meanings.
Clear the codes and check if they reappear upon restart.

3. Inspect Oil Level and Quality

Reinsert the dipstick, then remove it again to check the oil level.
If the oil is low, add the appropriate type and quantity of oil.
If the oil appears dirty or contaminated, consider an additional oil change.

Inspect the area around the oil filter and drain plug.
Tighten the drain plug and oil filter if they are loose.
Replace the oil filter if it shows signs of leakage.
