Steps for a Standard Oil Change

1. Drain Fluid: Place a catch pan under the vehicle and remove the drain plug to empty the old oil.
2. Replace Filter: Remove the used oil filter and install a fresh one, ensuring the rubber gasket is lightly lubricated.
3. Add New Oil: Pour the specified number of quarts into the oil fill port located on top of the engine.
4. Verify Level: Start the engine for a minute, then turn it off and check the dipstick to ensure the level is correct.

Essential Maintenance Guidelines

• Check Viscosity: Always use the specific oil weight recommended by the manufacturer, such as 0W-20 or 5W-30.
• Monitor Regularly: Inspect the oil level once per month to identify potential leaks or excessive consumption early.
• Reset Systems: After every oil change, reset the electronic oil life monitoring system on the digital dashboard display.
• Inspect Gaskets: Ensure the drain plug washer is in good condition to prevent slow leaks after the service is complete.
