Choosing the correct engine oil for your car protects internal components, maintains fuel efficiency, and prevents premature wear. For the 2019 Nissan Altima, the correct oil type is 0W-20 synthetic oil, and the engine oil capacity depends on whether you drive a 2.5-liter four-cylinder model or a 2.0-liter VC-Turbo model. Getting these specifications wrong can lead to poor performance, rough idling, or severe mechanical issues.
The competitor article incorrectly recommends 5W-20 and confuses engine lineups by mentioning an outdated V6 option that was never offered in the sixth-generation Altima. Let's look at the actual manufacturer specifications, exact fluid amounts, and a step-by-step DIY process so you can service your car right the first time.
Factory Oil Specifications for the 2019 Altima
Nissan updated its powertrain lineup for the sixth-generation Altima, dropping the older V6 engine entirely. Instead, owners choose between a naturally aspirated 2.5-liter four-cylinder engine or a high-tech 2.0-liter variable compression turbo engine.
2.5L Four-Cylinder Engine Specs
- Oil Type: Genuine Nissan Extra Service Oil or equivalent 0W-20 synthetic oil meeting API SN or SP certification standards.
- Oil Capacity: 5.1 US quarts (4.8 liters) when changing the oil and replacing the oil filter.
- Viscosity Preference: 0W-20 is engineered to flow quickly in sub-freezing winter conditions while maintaining protective film strength at operating temperatures.
2.0L VC-Turbo Engine Specs
- Oil Type: 0W-20 synthetic oil meeting standard API SN, SN-RC, or SP specifications.
- Oil Capacity: 5.4 US quarts (5.1 liters) with a filter change.
- Special Note: The variable compression engine features complex internal actuators. Using incorrect viscosity ratings like 5W-30 or conventional oils can disrupt hydraulic pressures and trigger check engine lights.

Why 0W-20 Synthetic Oil Matters
Switching from conventional lubricants to full synthetic options isn't just marketing hype. Modern engines feature tighter machining tolerances and complex emission controls that demand high performance from lubricants.
Synthetic base stocks resist thermal breakdown much better than crude-derived oils. When you commute in heavy stop-and-go traffic, your oil temperature climbs rapidly. Conventional oil thins out and loses film strength under these conditions, increasing metal-on-metal friction. Full synthetic 0W-20 maintains its viscosity across a broader temperature range.
According to guidelines from the Society of Automotive Engineers, low-viscosity oils like 0W-20 reduce internal parasitic drag during cold startups. This reduction helps your Altima achieve better fuel economy ratings without sacrificing engine protection.
Step-by-Step DIY Oil Change Procedure
Doing your own maintenance saves money and lets you inspect your car for leaks or wear. Gather your supplies before you start:
- 5 to 6 quarts of 0W-20 synthetic oil
- A replacement oil filter (OEM Nissan filter or Wix/Fram equivalent)
- A 14mm socket and ratchet
- An oil filter wrench
- A drain pan, funnel, and clean rags
- Safety glasses and jack stands
Step 1: Warm and Elevate the Engine
Run your Altima for five minutes to warm the oil, which helps suspended contaminants drain out completely. Shut off the engine, engage the parking brake, and safely raise the front end using a hydraulic floor jack. Secure the vehicle with heavy-duty jack stands. Never crawl under a car supported only by a hydraulic jack.
Step 2: Drain the Old Oil
Locate the oil drain plug on the bottom of the engine oil pan. Place your drain pan underneath. Use your 14mm socket to loosen the bolt counterclockwise, then carefully spin it out by hand while pushing inward so hot oil doesn't rush past your fingers too quickly. Let the oil drain completely for about ten minutes, then reinstall the drain plug with a new crush washer. Torque it snugly, avoiding over-tightening which strips the aluminum pan threads.
Step 3: Replace the Oil Filter
Position your drain pan under the oil filter location. On the 2.5L engine, the filter sits near the front bottom of the engine block. Unscrew the old filter counterclockwise using your filter wrench. Check the old filter to ensure the rubber gasket came off with it; leaving an old gasket stuck to the mounting base causes massive oil leaks. Dip a clean finger in fresh oil and smear a thin film onto the gasket of your new filter. Screw it on by hand until it seats firmly, then turn it an extra three-quarters of a turn.
Step 4: Refill and Test
Remove your oil filler cap under the hood and insert a clean funnel. Pour in 4.5 quarts of your 0W-20 synthetic oil, then check the dipstick. Slowly add more oil until the fluid level reaches the upper notch on the dipstick. Start the engine and let it idle for 30 seconds while checking underneath for leaks. Shut off the car, let the oil settle for two minutes, and take a final dipstick reading.
Common Mistakes to Avoid
- Overfilling the crankcase: Putting in a full 6 quarts because you bought a large jug creates excess internal pressure. This blows out seals and causes foaming, which reduces lubrication. Always check your manual's exact capacity.
- Reusing old crush washers: Skipping the drain plug washer replacement often results in slow, persistent oil drips on your driveway.
- Skipping filter changes: Installing fresh oil through a clogged, dirty filter instantly contaminates the new fluid with sludge. Always change both components together.
Frequently Asked Questions
Can I use 5W-30 in my 2019 Nissan Altima if 0W-20 is out of stock?
In an absolute emergency, you can use 5W-30 for a short top-off, but you shouldn't run a full oil change cycle with it. Thicker oil alters the hydraulic timing chain tensioner response and reduces fuel economy. Drain and replace it with the correct 0W-20 grade as soon as possible.
How often should I change the oil in a 2019 Altima?
Nissan recommends changing your oil every 5,000 to 7,500 miles or every six months, whichever comes first, when using synthetic oil under normal driving conditions. If you frequently drive in dusty areas, severe cold, or make lots of short trips under five miles, shorten your interval to 3,000 to 5,000 miles.
Why does my Altima use a small amount of oil between changes?
Modern high-efficiency engines with low-tension piston rings naturally consume a minor amount of oil—up to one quart every 1,000 to 1,500 miles is considered normal by most manufacturers. Check your dipstick every time you fill up your gas tank to catch low levels early.
