Understanding the correct 2017 altima oil type is fundamental to preserving the longevity and performance of Nissan’s popular mid-size sedan. While it may seem like a simple fluid, the oil selected for this specific model year acts as the lifeblood of the engine, managing temperature, reducing friction, and trapping contaminants. Choosing the wrong viscosity or failing to adhere to the manufacturer’s specifications can lead to decreased fuel economy, sluggish performance, and potentially severe mechanical damage over time.
2017 Altima Factory Specifications
Nissan equipped the 2017 Altima primarily with a 2.5-liter four-cylinder engine that delivers a balance of efficiency and power. To ensure this engine operates at peak efficiency, Nissan mandates the use of 0W-20 synthetic engine oil. This specific viscosity grade is critical for the advanced timing chain variable valve lift system (CVT) utilized in this powertrain. Furthermore, the oil must meet the dexos1 Gen 2 standard to ensure compatibility with the emissions control systems and to provide the necessary protection for the continuously variable transmission (CVT), which relies on the same fluid for both lubrication and hydraulic pressure.
Viscosity and Quality Requirements
The 0W-20 viscosity designation indicates the oil’s flow characteristics at low temperatures (0W) and its resistance to thinning at high temperatures (20). The "W" stands for winter, and the low number signifies that the oil remains fluid in cold conditions, allowing for easier starts and reduced wear on engine components during the initial startup phase. Synthetic formulations are strongly recommended because they provide superior thermal stability, resist oxidation better than conventional oils, and maintain their protective additives for a longer service interval, which is essential for the stop-and-go nature of daily driving.
Maintenance Intervals and Capacity
Adhering to the maintenance schedule is just as important as selecting the correct 2017 altima oil type. Nissan recommends an oil change interval of 7,500 miles under severe service conditions, though many drivers find that following the 6-month or 7,500-mile rule—whichever comes first—provides a good balance of protection and convenience. The engine oil capacity for the 2017 Altima is approximately 4.4 quarts, but this figure can vary slightly depending on the specific configuration, making it vital to verify the level with the dipstick after a refill to ensure the sump is neither overfilled nor underfilled.
Filter Selection and Installation
Equally critical to the oil itself is the filter used during the 2017 altima oil type replacement. A high-quality filter with the correct micron rating ensures that harmful particles are trapped effectively without restricting oil flow. Nissan typically specifies a filter that meets their NISSAN part number standard, which guarantees the gasket seals properly to prevent leaks and that the media is designed to handle the synthetic oil chemistry. Always replace the drain plug gasket during the oil change to prevent metal-on-metal contact that could cause the drain plug to fail prematurely.
Performance and Environmental Considerations
Utilizing the recommended synthetic 0W-20 oil directly impacts the 2017 Altima’s performance metrics. Owners will notice improved cold-start responsiveness, smoother acceleration through the CVT, and better fuel economy due to the reduced internal friction of the engine. From an environmental standpoint, using the correct oil weight contributes to lower emissions. Because the engine runs more efficiently, it burns fuel more completely, and the proper viscosity prevents the oil from burning off excessively, which can contribute to carbon buildup and smoke.
