How to Change Engine Oil on Nissan

Steps to Follow

Changing the oil is critical because it keeps the engine running smoothly. It removes dirt and debris that can damage the engine and helps improve fuel economy. Regular oil changes prolong the life of your engine, saving you money on repairs in the long run.
So, let’s define the basic steps for performing a car engine oil change.

Warm up the engine to operating temperature

Drain the used engine oil and remove the old oil filter

Install a new filter and fill with fresh oil

Check the oil level with a dipstick

By following these simple steps, you can service your car. Now let’s take a closer look at each of the steps, select the recommended oil and filter. At the end of this page I will answer possible questions.

Checking the quality of oil in Nissan

If your oil is dark and dirty, or if your car’s telling you it’s time for a service, you should change your oil as soon as you can. Driving with old oil can damage your engine.

Frequency (Interval) for Changing Engine Oil

Most cars need an oil change every 3,000 to 5,000 miles, but the Nissan Pathfinder can go up to 7,500 miles. But always check your manual. If you’re driving a lot of short trips, or in rough conditions, you may need to change it more often.

Check the Engine Oil Level in Nissan Pathfinder

Checking the engine oil level involves verifying the amount of oil present in the engine to ensure it is at an appropriate level. It is important to check the oil level periodically as part of regular vehicle maintenance. Here’s how you can do it:

1. Park your vehicle on a level surface and ensure the engine is turned off.
2. Open the hood of your car and locate the dipstick, which is usually marked with a bright-colored handle and labeled “Engine Oil.”
3. Remove the dipstick from its tube by pulling it out.
4. Wipe the dipstick clean using a cloth or paper towel to remove any existing oil.
5. Reinsert the dipstick fully back into its tube.
6. Pull out the dipstick again and observe the oil level on the end of the dipstick.
7. The dipstick will have markings indicating the minimum and maximum oil levels. The oil level should ideally be between these two marks.
8. If the oil level is below the minimum mark or significantly low, you may need to add oil to bring it up to the proper level. Consult your vehicle’s owner’s manual for the recommended oil type and the correct procedure for adding oil.

Checking the engine oil level periodically is important for several reasons:

1. Lubrication: Engine oil lubricates various components within the engine, preventing excessive friction and wear. Maintaining the proper oil level ensures effective lubrication and helps extend the life of engine parts.
2. Cooling: Oil helps dissipate heat generated by the engine. Insufficient oil can lead to overheating and potential damage to engine components.
3. Monitoring Oil Consumption: By checking the oil level regularly, you can monitor the rate at which your engine consumes oil. If you notice a significant decrease in oil level between checks, it may indicate an underlying issue that requires attention.
4. Early Detection of Problems: Visual inspection of the oil level can reveal signs of oil leaks or excessive oil consumption, which may indicate mechanical issues or malfunctioning components. Detecting problems early can prevent more extensive damage and costly repairs.

Visual (Express) Assessment of the Condition of Engine Oil in Nissan Pathfinder

A visual assessment of engine oil involves examining its appearance to determine its condition. You can perform a simple visual inspection to get an idea of the Nissan oil’s health. Here’s how you can do it:

1. Park your vehicle on a level surface and ensure the engine is off.
2. Open the hood and locate the dipstick for checking the engine oil level.
3. Remove the dipstick and wipe it clean with a cloth or paper towel.
4. Reinsert the dipstick fully and then remove it again.
5. Observe the color and consistency of the oil on the dipstick.

During the visual assessment, you should look for the following indicators:

1. Color: Fresh engine oil is typically amber or light brown in color. As it ages and accumulates contaminants, it becomes darker.
2. Consistency: The oil should have a smooth and uniform texture. If it appears gritty or contains metal particles, it may indicate potential engine problems.
3. Clarity: Clean engine oil is transparent or slightly translucent. If the oil appears cloudy or murky, it may suggest the presence of contaminants or water contamination.
4. Odor: Fresh engine oil usually has a mild petroleum smell. If you detect a burnt or strong odor, it could signify issues with the engine or oil breakdown.

Possible Questions after Nissan’s Self-Service

What Problems Can Arise after an Incorrect Self-Changing Engine Oil?

After an incorrect self-changing engine oil, several problems can occur:

1. Insufficient Lubrication: Using the wrong type or amount of oil can lead to inadequate lubrication, causing increased friction and potential engine damage.
2. Oil Contamination: If the oil is not properly drained or if contaminants are introduced during the oil change, it can lead to oil contamination. Contaminated oil can result in reduced engine performance and potential engine damage.
3. Leaks: Improperly installed oil filters or drain plugs can cause oil leaks, leading to a loss of oil and potential engine damage if not addressed.
4. Overfilling or Underfilling: Incorrectly measuring or adding the oil can result in overfilling or underfilling the engine. Overfilling can cause excess pressure and foaming, while underfilling can lead to insufficient lubrication.

It’s crucial to follow the correct procedures and use the recommended oil type and quantity to avoid these problems.

How Can I Check for Engine Oil Leaks after Changing It Myself?

To check for engine oil leaks after changing it yourself, follow these steps:

1. Park the vehicle on a clean and level surface.
2. Allow the engine to run for a few minutes to warm up.
3. Inspect the areas around the oil filter, drain plug, and oil pan for any signs of oil drips or wetness.
4. Use a clean rag or paper towel to wipe around these areas, checking for any fresh oil residue.
5. Pay attention to the underside of the vehicle, particularly around the oil pan and engine components.
6. Observe the oil level on the dipstick to ensure it remains stable and within the recommended range.
7. If you notice any leaks or abnormalities, it’s important to address them promptly. Double-check the installation of the oil filter and drain plug and consider seeking professional assistance if needed.

How to Reset the Oil Change Counter on Nissan Pathfinder after Service?

To reset the oil change counter on a Nissan Pathfinder after service, follow these steps:

1. Turn the ignition switch to the “ON” position without starting the engine.
2. Press the trip odometer reset button until “Maintenance” or “Reset” is displayed on the instrument cluster.
3. Press and hold the trip odometer reset button for about 10 seconds until the display starts flashing or the counter resets to zero.
4. Release the button and turn off the ignition.
5. The oil change counter should now be reset, indicating that the maintenance reminder has been cleared.

Note: The specific procedure may vary slightly depending on the model year and trim level of your Nissan Pathfinder. Refer to the owner’s manual for detailed instructions.

What to Do with Old Oil after Replacement?

After self-replacement of engine oil, it’s important to properly dispose of the old used oil. Here’s what you can do:

1. Collect the used oil in a clean, leak-proof container. Many auto parts stores or service stations accept used oil for recycling. Check with your local recycling centers or automotive retailers for drop-off locations.
2. Avoid mixing the used oil with other fluids or contaminants. Keep it separate to maintain its recyclability.
3. Do not pour the used oil down drains, into the ground, or dispose of it with regular household waste. Improper disposal can harm the environment and is illegal in most jurisdictions.

Remember to follow local regulations and guidelines for disposing of used oil in an environmentally responsible manner.
