Step 7: Check the Oil Level

After adding the new oil, replace the oil filler cap and start the engine for a few minutes. turn off the engine and wait for a few minutes to allow the oil to settle. Then, use the dipstick to check the oil level. Adjust if necessary.

Step 8: Properly Dispose of the Old Oil
