For a 2014 Nissan Altima, the recommended oil depends on the engine. The 2.5L four-cylinder uses 0W-20 full synthetic oil, while the 3.5L V6 uses 5W-30 full synthetic oil. Both should meet API SN or newer and ILSAC GF-5 standards.
Engine-specific oil recommendations
The Altima was offered with two engines in 2014. The following breakdown outlines the official oil types they require.
2.5L four-cylinder (QR25DE): 0W-20 full synthetic oil that meets API SN or newer and ILSAC GF-5. Oil capacity is typically about 4.5–4.7 quarts with a filter.
3.5L V6 (VQ35DE): 5W-30 full synthetic oil that meets API SN or newer and ILSAC GF-5. Oil capacity is typically about 5.5–5.7 quarts with a filter.
Note: Exact oil capacity can vary by model and region; always confirm from the owner's manual or Nissan's official specifications.
Climate and viscosity considerations
Using synthetic oil provides better protection, easier cold starts, and longer service intervals. The climate you drive in can influence the grade selection; 0W-20 is particularly suitable for colder climates, while 5W-30 remains a solid choice in a wide range of conditions. If 0W-20 is unavailable, 5W-30 can be used as a temporary fallback, but you should revert to the recommended 0W-20 when possible.
For best results, always follow Nissan’s guidance in the owner’s manual and use a quality synthetic oil that meets API SN and ILSAC GF-5 standards.
How to check and change the oil
If you plan to perform or supervise an oil change yourself, use these basic steps as a guide. Always ensure the engine is cool and on a level surface before starting.
- Park on level ground, apply the parking brake, and gather the new oil, filter, and necessary tools.
- Drain the old oil by removing the drain plug and allow it to completely drain into a proper container.
- Replace the oil filter with a new one and lubricate the filter gasket with a little new oil.
- Refill with the recommended oil type and approximate capacity (0W-20 for the 2.5L or 5W-30 for the 3.5L).
- Start the engine, run for a few minutes, then turn off and check the oil level with the dipstick; top up as needed and recheck after a few minutes.
Regular oil changes help maintain engine performance and longevity. If you’re unsure about performing an oil change, have it done at a certified shop.
Plain-language takeaway
In short, choose 0W-20 full synthetic oil for the 2.5L engine, or 5W-30 full synthetic oil for the 3.5L engine, ensuring the oil meets API SN and ILSAC GF-5 standards.
Summary
The 2014 Nissan Altima requires synthetic motor oil matched to its engine: 0W-20 for the 2.5L four-cylinder and 5W-30 for the 3.5L V6, with API SN/ILSAC GF-5 compliance. Check the owner’s manual for exact capacity and any regional variations, and consider climate when choosing viscosity. Use a high-quality synthetic oil and change the filter at the recommended intervals for optimal engine health.
