Motor oil is the lifeblood of your car’s engine. It serves as a lubricant, reducing friction between moving parts, and as a coolant, helping to remove excess heat. The engine’s performance, fuel efficiency, and longevity heavily depend on the quality and condition of the motor oil. Regular oil changes and using the right oil are essential for running your vehicle smoothly.
Nissan Motor Oil 0W-20 SN is a high-performance synthetic engine oil specifically designed for Nissan vehicles. The “0W-20” denotes the oil’s viscosity, which is a measure of how easily it flows at different temperatures. The lower the number before the W, the better the oil performs in cold weather, while the second number indicates how well it maintains its thickness in high temperatures.
The “SN” is an API (American Petroleum Institute) service classification that signifies the oil meets certain performance standards regarding fuel economy and emission system protection.
When it comes to maintaining your Nissan vehicle, it’s crucial to follow the manufacturer’s recommendations for motor oil. Using the wrong oil can cause damage to the engine or other components, and it might void the New Vehicle Limited Warranty.
Nissan recommends using “NISSAN Motor Oil 0W-20 SN” or its equivalent. If the specified oil is not available, a synthetic 0W-20 GF-5 SN motor oil may be used as long as it meets certain standards.
Adhering to these guidelines ensures that your vehicle performs at its best and that you remain protected under Nissan’s warranty.

Understanding Motor Oil Specifications
Viscosity ratings (0W-20) and what they mean:
Viscosity is a measure of a fluid’s resistance to flow. In the context of motor oil, it indicates how thick or thin the oil is at various temperatures. The viscosity rating of motor oil is usually represented as a combination of two numbers, such as 0W-20.
The first number followed by the letter “W” (which stands for Winter) represents the oil’s viscosity at low temperatures (cold weather), and the second number represents the viscosity at high temperatures (100 degrees Celsius).
A 0W-20 oil is very thin at cold temperatures, allowing it to flow easily and provide quick lubrication during cold starts. At high temperatures, it maintains enough thickness to provide adequate protection.
API service classifications (SN) and their significance:
API service classifications are a set of standards that define the performance properties of motor oils. The classifications are represented by two letters, where the first letter is “S” for gasoline engines and “C” for diesel engines.
The second letter indicates the level of performance, with each subsequent letter representing a higher standard. “SN” is one of the more recent classifications and is designed for use in vehicles manufactured in 2011 and later.
It places a strong emphasis on fuel economy, emission system compatibility, and protection against engine deposits and wear.
ILSAC GF-5 standard and its relevance to engine protection:
ILSAC stands for International Lubricant Standardization and Approval Committee. The GF-5 standard is one of the specifications set by this committee and is recognized internationally. This standard was developed to address several critical performance aspects of motor oil, including fuel economy, emission system protection, oil robustness, and engine cleanliness.
Motor oils that meet the ILSAC GF-5 standard have undergone rigorous testing and are proven to offer high levels of protection against engine wear, deposits, and sludge, while also contributing to improved fuel efficiency.
For modern engines, especially those in Nissan vehicles, using an oil that meets the GF-5 standard is vital for maintaining engine performance and longevity.

- Protecting Against Wear: The protective properties of synthetic oils shield engine components from wear, which can significantly extend the lifespan of the engine.
- Keeping Engines Clean: By reducing sludge and deposit formation, synthetic oils help maintain engine cleanliness, which is crucial for optimal performance.
- Optimizing Fuel Efficiency: The reduced internal friction provided by synthetic oils can lead to better fuel efficiency, which not only saves money but also contributes to lower emissions.
Practical Tips For Oil Change
When to change motor oil:
- Manufacturer Recommendations: Always consult your vehicle’s owner’s manual for the manufacturer’s recommendations on oil change intervals.
- Oil Life Monitors: Some vehicles are equipped with oil life monitors that will alert you when it’s time to change the oil based on driving conditions and engine performance.
- Mileage and Time: A common guideline is to change the oil every 3,000 to 5,000 miles, or every 3 to 6 months, whichever comes first. However, synthetic oils often allow for longer intervals.
- Visual and Sensory Checks: Regularly check the oil level and condition. If the oil is unusually dark, has a burnt smell, or is at a low level, it may be time for an oil change.
How to change motor oil safely and efficiently:
- Gather Materials: Make sure you have the right oil, a new oil filter, a wrench, an oil filter wrench, a drain pan, a funnel, and protective gloves.
- Warm Up the Engine: Start the engine for a few minutes to warm up the oil, as warm oil drains faster.
- Drain the Old Oil: Position the drain pan under the oil drain plug. Remove the plug with a wrench and let the oil drain out.
- Remove and Replace the Oil Filter: Use an oil filter wrench to remove the old filter. Before installing the new filter, apply a small amount of oil to the gasket for a better seal.
- Add New Oil: Use a funnel to pour the new oil into the engine. Be careful not to overfill.
- Check the Oil Level: Start the engine for a few minutes, then check the oil level with the dipstick. Add more if necessary.
Tips For Recycling Or Disposing Of Used Motor Oil
