The “Oil Change Required” light on your 2018 Infiniti QX80 can be a bit of a nuisance, but it’s a vital reminder to keep your engine running smoothly. Knowing how to reset this light after an oil change is crucial for maintaining your vehicle’s health and ensuring optimal performance. This guide will walk you through the process, step-by-step, so you can confidently reset the oil light yourself.

Understanding the Oil Light

The oil light on your 2018 Infiniti QX80 is a critical indicator of your engine’s health. It’s triggered by a sensor that monitors the oil level and quality. When the light illuminates, it’s a clear signal that your vehicle needs an oil change. Ignoring this light can lead to serious engine damage, so it’s essential to address it promptly.

Essential Tools and Supplies

Before you begin, gather the following:

• A clean rag or towel: To wipe away any spills or drips.
• A reliable car jack and jack stands: To safely lift your vehicle for access to the oil dipstick.
• The correct type of engine oil: Refer to your owner’s manual for the recommended oil viscosity and type for your 2018 QX80.
• New oil filter: Always use a high-quality oil filter that’s compatible with your vehicle.
• Oil drain pan: To collect the used oil.
• Wrench or socket set: To loosen the oil drain plug.
• Gloves: To protect your hands from oil and grime.

Step-by-Step Guide to Resetting the Oil Light

Here’s a detailed breakdown of the process:

1. Warm Up Your Engine: Start your 2018 Infiniti QX80 and let the engine run for a few minutes to warm up the oil. This will make it easier to drain.
2. Park on a Level Surface: Find a safe spot with a level surface to park your vehicle. Engage the parking brake and ensure the vehicle is secure.
3. Locate the Oil Drain Plug: Open your hood and locate the oil pan. The drain plug is usually situated at the bottom of the pan.
4. Place the Oil Drain Pan: Position the drain pan underneath the oil drain plug, ensuring it’s large enough to catch all the oil.
5. Loosen the Oil Drain Plug: Use a wrench or socket set to loosen the oil drain plug. Be careful not to overtighten it when you re-install it later.
6. Drain the Oil: Allow the oil to drain completely into the pan. This may take a few minutes.
7. Remove the Old Oil Filter: Locate the oil filter, which is typically attached to the engine block near the oil pan. Use a filter wrench to loosen and remove the old filter.
8. Install the New Oil Filter: Apply a thin coat of fresh oil to the new filter’s gasket. Screw the new filter onto the filter housing, hand-tightening it first and then using the filter wrench to tighten it securely. Do not overtighten.
9. Replace the Oil Drain Plug: Replace the oil drain plug and tighten it securely. Use a torque wrench to ensure proper tightening.
10. Add New Oil: Carefully pour the correct amount of new engine oil into the oil filler neck, which is usually located on the top of the engine. Refer to your owner’s manual for the recommended oil capacity.
11. Check the Oil Level: Once you’ve added the oil, check the oil level using the dipstick. The oil level should fall between the “Full” and “Low” marks on the dipstick.
12. Start the Engine: Start your engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
13. Reset the Oil Light: Now, it’s time to reset the oil light. The process varies depending on your QX80’s model year and trim level. Here are two common methods:

• Method 1 (Using the Instrument Panel):
• Turn the ignition key to the “ON” position (without starting the engine).
• Press and hold the “TRIP” button on your steering wheel until the oil light blinks.
• Release the “TRIP” button.
• The oil light should now be reset.
• Method 2 (Using a Scan Tool):
• Connect a scan tool to your vehicle’s diagnostic port, typically located under the dashboard.
• Follow the scan tool’s instructions to access the oil service reminder and reset it.

14. Final Check: Once you’ve reset the oil light, start the engine again and check the oil level one more time. Ensure there are no leaks or other issues.

Additional Tips and Precautions

• Always use the correct type of oil: Refer to your owner’s manual for the recommended oil viscosity and type for your 2018 QX80. Using the wrong type of oil can damage your engine.
• Check the oil level regularly: Even after an oil change, it’s important to check the oil level regularly, especially during the first few weeks after the change.
• Dispose of used oil properly: Never pour used oil down the drain or into the ground. Dispose of it at a designated recycling center or auto parts store.
• Consider professional service: If you’re not comfortable performing an oil change yourself, it’s best to take your 2018 Infiniti QX80 to a qualified mechanic for service.
