Oil Capacity Overview by Engine Type
The 2019 Nissan Altima comes with two main engine options, the 2.5-liter four-cylinder and the 2.0-liter turbocharged engine. Each engine has slightly different oil requirements, so it is important to know the exact capacity before performing an oil change. Using the correct amount of oil ensures proper lubrication, cooling, and protection for all internal components.
For the 2.5L engine, the correct oil capacity is 4.9 quarts (4.6 liters) when the oil filter is replaced. Nissan recommends using SAE 0W-20 full synthetic motor oil for this engine. This oil type offers excellent low-temperature performance and reduces friction, helping the engine operate smoothly and efficiently. It also meets the API SN and ILSAC GF-6 standards, which means it protects against sludge buildup and improves fuel economy.
If your 2019 Altima has the 2.0L turbocharged engine, the oil capacity increases slightly to 5.0 quarts (4.7 liters) with a new filter. Like the 2.5L, it also requires 0W-20 full synthetic oil, but because of the higher operating temperatures of a turbo engine, choosing a premium synthetic oil brand is even more critical. Oils from trusted manufacturers such as Mobil 1, Castrol Edge, or Valvoline Advanced Full Synthetic are all excellent choices.
Always check the oil level after refilling by using the dipstick. The oil should be between the MIN and MAX marks. Overfilling can cause foaming, excess pressure, and potential leaks, while underfilling may lead to poor lubrication and engine wear.
Knowing your 2019 Nissan Altima oil capacity and following the manufacturer’s specifications is the best way to keep your vehicle performing at its peak.
Recommended Oil Types for the 2019 Nissan Altima
Choosing the right engine oil is just as important as knowing the correct 2019 Nissan Altima oil capacity. The oil type directly affects how well the engine performs, how efficiently it burns fuel, and how long its internal parts last. For both the 2.5L and 2.0L turbo engines, Nissan recommends 0W-20 full synthetic motor oil because it offers the best balance of performance, protection, and fuel economy.
Full synthetic oil flows easily even at low temperatures, which is essential for quick lubrication during cold starts. It also resists thermal breakdown at high temperatures, a crucial factor for the 2.0L turbocharged engine that operates under higher pressure and heat. Using 0W-20 synthetic oil ensures a consistent layer of protection inside the engine, reducing friction and preventing premature wear.
Several trusted brands produce high-quality 0W-20 oils that meet or exceed Nissan’s requirements. Mobil 1 Advanced Fuel Economy 0W-20, Castrol Edge Full Synthetic 0W-20, and Valvoline Advanced Full Synthetic 0W-20 are among the most recommended choices. Each of these oils meets the API SP and ILSAC GF-6 standards, providing enhanced oxidation stability and improved sludge control.
When selecting an oil, it is also helpful to consider your driving environment. Drivers in hot climates or who frequently drive in stop-and-go traffic may benefit from oils formulated for high-temperature performance. On the other hand, those in colder regions should look for oils with excellent cold-start capabilities to reduce engine strain.
Using the correct oil type for your Altima is more than just following a manual recommendation. It is a smart way to maintain smooth engine operation, optimize fuel efficiency, and extend the life of your vehicle.
How to Check and Change Engine Oil
Knowing the correct 2019 Nissan Altima oil capacity is only part of proper maintenance. You also need to know how to check and change the oil correctly. Regular oil changes keep your engine clean, prevent overheating, and ensure long-term performance. Even if you are not a professional mechanic, changing the oil in your Altima is a simple process that can be done at home with basic tools.
To check the oil level, first make sure the car is parked on a flat surface and the engine is off. Wait at least five minutes after shutting it down so the oil can settle in the pan. Open the hood and locate the yellow dipstick. Pull it out, wipe it clean with a cloth, insert it back, and then pull it out again to read the level. The oil should be between the MIN and MAX marks. If the level is low, add oil in small amounts until it reaches the correct mark, being careful not to overfill.
Changing the oil requires a few tools such as a socket wrench, a drain pan, and a new oil filter. Warm up the engine for a few minutes so the oil flows easily, then remove the drain plug and allow the old oil to drain completely. Replace the drain plug securely, remove the old oil filter, and install the new one. Once everything is in place, pour in the recommended amount of fresh 0W-20 full synthetic oil according to your engine type.
After refilling, start the engine and let it run for a minute, then recheck the oil level using the dipstick. This ensures the oil is evenly distributed throughout the system. Maintaining the proper oil level is one of the easiest ways to protect your Altima’s engine and keep it performing like new.
Oil Change Interval and Maintenance Tips
Understanding the correct 2019 Nissan Altima oil capacity is important, but knowing when to change the oil is equally vital. Regular oil changes prevent buildup of dirt and carbon deposits that can cause internal wear or reduced performance. Nissan recommends changing the engine oil every 5,000 to 7,500 miles, depending on your driving conditions and habits. Drivers who spend a lot of time in stop-and-go traffic or frequently take short trips should aim for the lower end of that range since the engine rarely reaches optimal temperature for burning off moisture and contaminants.
Modern Altimas are equipped with an oil life monitoring system that helps determine when service is needed. When the indicator light appears on your dashboard, it means the oil quality has dropped and should be replaced soon. However, it is still wise to check the oil level manually between services, especially before long trips or after heavy driving.
To keep your engine running at its best, always use the correct oil type and avoid mixing different grades. Replace the oil filter every time you change the oil to ensure proper filtration and pressure. Clean filters prevent debris from circulating through the engine, reducing wear and improving longevity.
It is also good practice to inspect for oil leaks around the drain plug and filter after each service. A small leak may seem harmless but can lead to oil loss and eventual engine damage if left unchecked. Keeping a maintenance log with dates and mileage can help you stay consistent with oil changes and other services.
By following these simple maintenance tips, your 2019 Nissan Altima will deliver smoother performance, better fuel economy, and a longer engine life. Consistent care and correct oil management are key to preserving the quality and reliability that Nissan is known for.
Common Mistakes and Troubleshooting
Even with the correct 2019 Nissan Altima oil capacity and type, small mistakes during maintenance can lead to major issues over time. Understanding these common errors will help you avoid unnecessary engine problems and expensive repairs.
One of the most frequent mistakes is overfilling the oil. Many drivers assume that adding a little extra will provide more protection, but this can cause excessive pressure inside the crankcase. The result is foaming, leaks, and even gasket failure. Always check the dipstick carefully after refilling to make sure the level stays between the minimum and maximum marks.
Another common issue is using the wrong oil type. Some owners switch to thicker or cheaper conventional oils thinking it will save money. However, using anything other than the recommended 0W-20 full synthetic can reduce fuel efficiency and prevent proper lubrication. The engine in the Altima is designed for specific viscosity and additive properties, so deviating from those specifications can shorten its lifespan.
Neglecting the oil filter is also a frequent oversight. An old or clogged filter restricts oil flow and increases internal friction. Always replace the oil filter with every oil change, even if it appears clean. This ensures that contaminants are properly removed and the engine maintains the correct oil pressure.
Finally, ignoring oil leaks can be dangerous. If you notice dark spots under your car or smell burning oil, inspect the drain plug, filter seal, and gasket immediately. Fixing small leaks early prevents severe damage later.
By paying attention to these details, you can keep your Altima’s engine healthy and avoid costly repairs. Proper oil care is more than routine maintenance-it is the foundation of long-term vehicle reliability.
