Refer to your owner's manual for the most up-to-date recommendations.

It's also important to look for oils that meet the ILSAC GF-5 or GF-6 specification. These standards ensure the oil provides adequate protection against wear, deposits, and oxidation.

3.5L VQ35DE Engine Oil Recommendation

The 2014 Nissan Altima with the 3.5L VQ35DE engine typically requires SAE 5W-30 engine oil. This heavier viscosity provides better protection for the V6 engine's higher output and operating temperatures. While some sources might suggest other viscosities depending on climate, 5W-30 is the generally accepted and recommended grade. Always confirm with your owner's manual.

Similar to the 2.5L engine, ensure the oil meets the ILSAC GF-5 or GF-6 specification for optimal engine protection.

Understanding Oil Specifications: SAE and ILSAC

Navigating the world of engine oil can be confusing, especially with terms like SAE and ILSAC. Here's a quick breakdown:

SAE (Society of Automotive Engineers): This organization defines the viscosity grades of engine oil. The numbers (e.g., 0W-20, 5W-30) indicate the oil's flow characteristics at different temperatures. The "W" stands for "Winter," and the number before it indicates the oil's viscosity at cold temperatures. The number after the "W" indicates the oil's viscosity at operating temperatures.
ILSAC (International Lubricant Standardization and Approval Committee): ILSAC is a joint venture between American and Japanese automobile manufacturers. They develop minimum performance standards for engine oils. Look for the ILSAC starburst symbol on the oil container, indicating that the oil meets the latest standards (currently GF-6).

Engine Oil Change Intervals for the 2014 Altima

Regular oil changes are crucial for maintaining your 2014 Altima's engine health. The recommended oil change interval depends on driving conditions and the type of oil used.

Conventional Oil Change Intervals

If you're using conventional engine oil, Nissan typically recommends changing the oil every 3,000 to 5,000 miles, or every 6 months, whichever comes first. Shorter intervals are recommended for severe driving conditions, such as frequent stop-and-go traffic, towing, or driving in dusty environments.

Synthetic Oil Change Intervals

Synthetic engine oil offers superior protection and allows for longer oil change intervals. With synthetic oil, you can typically extend the interval to 7,500 to 10,000 miles, or every 12 months, whichever comes first. Again, severe driving conditions may warrant more frequent oil changes.

Nissan's Maintenance Minder System

Many 2014 Altimas are equipped with a maintenance minder system that monitors driving conditions and alerts you when an oil change is needed. While this system is a helpful guide, it's still essential to understand the basic oil change intervals and adjust them based on your driving habits. Pay close attention to the indicator and consult your owner's manual for more details.

Choosing the Right Type of Engine Oil: Conventional vs. Synthetic

The debate between conventional and synthetic oil continues, but synthetic oil generally offers several advantages:

Better Protection: Synthetic oil provides superior protection against wear, deposits, and oxidation, especially at high temperatures.
Improved Fuel Economy: Synthetic oil's improved flow characteristics can lead to slightly better fuel economy.
Extended Oil Change Intervals: As mentioned earlier, synthetic oil allows for longer oil change intervals, saving you time and money in the long run.
Better Cold-Start Performance: Synthetic oil flows more easily at cold temperatures, providing better lubrication during cold starts.

While synthetic oil is generally more expensive than conventional oil, the benefits often outweigh the cost, especially for modern engines like those in the 2014 Altima. Consider the long-term benefits when making your decision.

DIY Oil Change vs. Professional Service

Changing your own oil can save you money, but it requires some knowledge, tools, and proper disposal methods. Here's a quick comparison:
