The 2014 Nissan Altima uses SAE 5W-30 motor oil, with full synthetic oil strongly preferred for best protection and longevity.
This recommendation applies to both of the model’s engines—the 2.5-liter four-cylinder and the 3.5-liter V6—and you should confirm the exact specification for your vehicle in the owner's manual or on the under-hood oil filler sticker.
Engine-specific oil requirements
Below is a concise guide to the oil type and viscosity recommended for each engine option in the 2014 Altima:
- 2.5L 4-Cylinder: SAE 5W-30 motor oil; synthetic oil is recommended for optimal protection, API SN or newer.
- 3.5L V6: SAE 5W-30 motor oil; synthetic oil is recommended for optimal protection, API SN or newer.
Note: Some regional markets may have slightly different specifications according to local service bulletins; always defer to the owner's manual and the under-hood label for your exact build.
How to confirm the exact oil spec for your car
Check the owner’s manual, the oil filler cap, or the sticker under the hood on your Altima. Nissan's service portal and your local dealer can also confirm the exact spec based on your VIN and market.
Synthetic vs conventional oil
Nissan recommends synthetic oil for better protection and easier cold starts, though conventional 5W-30 may be acceptable if synthetic is unavailable. Using a high-quality synthetic typically supports more consistent viscosity and may allow longer service intervals.
Summary
For a 2014 Altima, the recommended oil is SAE 5W-30, with full synthetic preferred, for both the 2.5L four-cylinder and the 3.5L V6. Always verify the exact specification for your vehicle in the owner's manual or with a Nissan dealer, especially if you’re in a region with different guidance.
