Understanding the 2017 Nissan Altima oil type is fundamental to ensuring the longevity and performance of this popular mid-size sedan. The 2.5-liter four-cylinder engine, which powers the majority of the base and mid-level trims, is designed to operate efficiently with a specific viscosity and quality of motor oil. Using the incorrect specification can lead to increased friction, reduced fuel economy, and potentially severe engine damage over time, making this a critical maintenance item for any owner.
Manufacturer Specifications and Recommendations
For the heart of the 2017 Altima, Nissan provides precise guidance that should always be the primary reference for any maintenance task. The factory fill and recommended replacement interval rely on meeting specific API and ILSAC standards.
API and ILSAC Standards
To meet stringent fuel economy targets and emissions requirements, the 2017 model year calls for motor oil that meets the GF-5 specification. This standard ensures the oil provides the necessary protection for the timing chain and variable valve timing mechanisms while maintaining cleanliness. Look for the API "GF-5" starburst symbol on the oil container to confirm compatibility.
Viscosity Grade: The Cold and Hot Flow
The viscosity, or thickness, of the oil is arguably the most critical characteristic for the 2017 Altima. Nissan specifies 0W-20 as the ideal viscosity for the 2.5L 4-cylinder engine. The "0W" indicates the oil's flowability at cold temperatures, allowing for easier starts in freezing weather, while the "20" denotes its resistance to thinning at operating temperature. This low-viscosity formula reduces drag, helping the engine run cooler and improving gas mileage.
Synthetic vs. Conventional Oil Options
With the correct viscosity and GF-5 rating established, the next decision involves the type of base stock used to formulate the oil. Both synthetic and conventional options are available, and choosing between them depends on driving habits, climate, and budget.
Conventional Oil for Budget-Centric Drivers
Conventional motor oil, refined from crude oil, remains a viable option for the 2017 Altima. It meets the GF-5 standard and provides adequate protection for engines subjected to moderate driving conditions. Owners who primarily use their vehicles for short trips or in less demanding environments can find conventional 0W-20 to be a cost-effective solution. However, it tends to break down faster under high stress and requires changes at the standard 3,000 to 5,000-mile interval.
Full Synthetic for Maximum Protection
Full synthetic oil is engineered through chemical processes to provide superior performance across a wide temperature range. For the 2017 Altima, synthetic 0W-20 offers enhanced resistance to oxidation, better viscosity stability, and superior protection against sludge. This is particularly beneficial for owners who frequently drive in stop-and-go traffic, tow trailers, or operate in extreme hot or cold climates. While the initial cost is higher, the extended change intervals—often up to 7,500 or 10,000 miles for some drivers—can offset the price difference over the life of the vehicle.
Special Considerations for the 2017 Model
Beyond the basic specifications, there are specific nuances related to the 2017 Altima that owners should be aware of when selecting oil.
High Mileage Formulations
For owners with significant mileage on the odometer, high-mileage synthetic blends are an excellent choice. These oils contain seal conditioners that help restore flexibility to hardened engine gaskets, reducing oil consumption and external leaks. They also include additional detergents to keep aging engine internals clean.
