2018 Nissan Armada Oil Capacity

Got it? Now, let's talk about how much oil your 2018 Nissan Armada needs. The oil capacity for the 5.6-liter V8 engine is approximately 7.9 quarts (7.5 liters) with a new filter. It's always a good idea to double-check this information in your owner's manual or on the oil filter itself, as specifications can sometimes vary slightly. When you're changing your oil, make sure you have enough oil on hand to fill the engine completely. It's better to have a little extra than to run short. This capacity ensures that your engine has sufficient lubrication to function correctly, keeping all the internal components protected and operating smoothly. Keep in mind that this is the total capacity, including the oil filter. When changing the oil, you'll need to account for the oil that remains in the engine and the new oil that will fill the filter. Overfilling the engine with oil can be just as harmful as underfilling it, leading to issues such as oil leaks and engine damage. So, be sure to measure carefully and follow the manufacturer's recommendations.

Always check the oil level with the dipstick after adding oil. Let the engine sit for a few minutes after adding the oil so that the oil can settle. Then, pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick. Adding the right amount of oil is important for ensuring that the engine is properly lubricated without being overfilled. Overfilling can cause the oil to be forced into areas where it shouldn’t be, leading to leaks and potential damage. Underfilling, on the other hand, can lead to insufficient lubrication, causing friction and wear on engine components.

Best Practices for Oil Changes and Maintenance

Alright, so you know the oil type and capacity for your 2018 Nissan Armada. Now, let's talk about keeping your engine happy with regular oil changes and maintenance. Here are a few tips:

• Follow the Recommended Oil Change Intervals: Nissan typically recommends changing your oil every 7,500 miles or every six months, whichever comes first. However, if you drive in severe conditions (like stop-and-go traffic, extreme temperatures, or towing), you might need to change your oil more frequently. Always check your owner's manual for the most accurate and up-to-date recommendations. Regular oil changes are crucial for removing contaminants and maintaining the oil’s lubricating properties.
• Use a Quality Oil Filter: Don't skimp on the oil filter! A good quality filter will trap contaminants and keep your engine clean.
