In plain terms, the 2010Altima uses SAE 5W-30 engine oil for both the 2.5-liter four-cylinder and the 3.5-liter V6. You may use conventional, synthetic-blend, or full synthetic oil as long as it meets current API service standards and suits your climate. Always confirm with the owner's manual or the oil cap if you’re unsure.
Engine options and oil requirements
The Altima lineup for 2010 included two engines. Both share the same basic oil viscosity recommendation, but it’s worth noting the model’s most common configurations.
- 2.5L QR25DE: recommended viscosity 5W-30. You can choose conventional, synthetic-blend, or full synthetic oil that meets API service standards.
- 3.5L VQ35DE: recommended viscosity 5W-30. Use oil that meets API service standards; synthetic options are acceptable.
In practice, both engine variants in 2010 require the same 5W-30 viscosity. Using the right grade helps protect the engine across temperatures and driving styles.
Oil types and approvals
Beyond viscosity, owners have options for the oil base (conventional vs synthetic) as long as the product meets Nissan’s and API/ILSAC standards. Here’s a quick guide to what to look for when shopping for oil for your Altima.
- Viscosity: 5W-30 is standard for both the 2.5L and 3.5L engines.
- Oil type: conventional 5W-30 or synthetic-blend/full synthetic 5W-30, as long as it meets API service standards and is suitable for the climate.
- Brand and certification: choose a reputable brand and oils labeled for API SN or newer and ILSAC GF-5 or newer, or as specified by the manual.
Bottom line: opt for a 5W-30 oil that meets API and ILSAC standards, whether conventional or synthetic, and follow Nissan’s suggested service intervals found in the manual.
Summary
The 2010 Nissan Altima requires 5W-30 engine oil for both the 2.5L and 3.5L engines. You can use conventional or synthetic variants, as long as they meet API/ILSAC standards. Confirm the exact specification in the owner's manual or on the engine oil cap, especially if you operate in extreme temperatures or have high-mileage notes.
