The 2019 Nissan Altima SL generally requires 0W-20 full-synthetic motor oil if it has the 2.5-liter engine; if your SL is equipped with the 2.0-liter VC-Turbo engine, the recommended grade is 0W-30 full-synthetic oil. Always verify the exact specification for your vehicle using the VIN and the owner's manual.
The oil specification for the Altima varies by engine option. The 2019 Altima offered two engine choices in SL trim: the standard 2.5L I4 and the available VC-Turbo 2.0L. Understanding which engine your car has is important because it determines the correct oil viscosity and type. Below are the engine-specific recommendations to help you choose the right oil.
Engine options and oil specifications
For clarity, here are the recommended oil grades by engine option for the 2019 Altima SL.
2.5L I4 engine (non-turbo)
- Oil viscosity: 0W-20
- Oil type: Full synthetic
- Recommended spec: ILSAC GF-6 or API SP (or newer)
- Notes: Use Nissan-approved or OEM-recommended 0W-20 oils for best performance and fuel efficiency

How to verify the correct oil for your Altima SL
Check the owner’s manual section on engine oil, the oil fill cap, or the vehicle’s information label (often found near the engine bay). If you’re unsure about which engine your car has, or if you bought a used SL, contact a Nissan dealer with your VIN to confirm the exact oil specification.
