How to Choose and Change Oil for a 2019 Nissan Maxima

If you own a 2019 Nissan Maxima, the oil you use is more than just a lubricant – it’s a key factor in the car’s performance, fuel economy, and longevity. Below we break down the essential details you need to know about 2019 Nissan Maxima oil, from the right viscosity to the step‑by‑step change process.

What Nissan Recommends: Viscosity and Type

The factory recommendation for the 2019 Maxima is a full‑synthetic 0W‑20 oil. This low‑viscosity oil flows quickly at cold‑start temperatures, protecting engine components while still providing a thin film at operating heat. Using a different grade, such as 5W‑30, can lead to reduced fuel efficiency and may even void warranty coverage.

Because the Maxima’s VQ35DE engine is designed around the 0W‑20 spec, sticking with a reputable synthetic brand—Mobil 1, Castrol Edge, or Nissan’s own Genuine Motor Oil—ensures you get the proper additive package for wear protection and deposit control.

How Much Oil Does the Engine Hold?

The total oil capacity, including the filter, is roughly 5.0 quarts (about 4.7 L). When you’re doing a drain‑and‑fill, aim for 4.8–5.0 quarts, then top off after checking the dipstick. Overfilling can cause foaming and increased pressure, while underfilling leaves critical surfaces uncovered.

When to Change the Oil

Nissan’s maintenance schedule suggests an oil change every 5,000 – 7,500 miles when you stick with full synthetic. If you do a lot of short trips, drive in extreme temperatures, or tow a trailer, consider the lower end of that range. Many owners find a 6,000‑mile interval works well for everyday driving.

In addition to mileage, pay attention to the oil life indicator on the dashboard. The system monitors engine load, temperature, and driving habits, and will warn you when it’s time for a change.

Checking the Oil Level – A Quick Routine

• Warm up the engine for a few minutes, then turn it off and wait a minute.
• Pull the dipstick, wipe it clean, reinsert fully, and pull it out again.
• Read the level; it should sit between the “MIN” and “MAX” marks, ideally near the middle.
• If the oil looks dark but not gritty, a change is probably due. If it’s milky, you may have coolant mixing—seek professional help.

Benefits of Sticking with Synthetic 0W‑20

Synthetic oil offers better resistance to thermal breakdown, which means the Maxima’s high‑performance V‑6 stays protected during spirited driving or hot summer days. It also flows more readily at low temperatures, reducing engine wear during cold starts—a frequent scenario for many drivers.

In addition, synthetic formulations often contain detergents that keep the oil clean, preventing sludge buildup that can impair valve timing and reduce power.

Can You Use Conventional Oil?

While it’s technically possible to run a conventional 5W‑30 in a pinch, it’s not advisable for long‑term use. Conventional oil is thicker at start‑up, which can increase wear on camshafts and lifters. Moreover, it lacks the high‑temperature stability needed for the Maxima’s variable valve timing system.

Switching back to conventional after using synthetic can also cause oil filter incompatibility, as some filters are designed for synthetic flow rates.

Step‑by‑Step Oil Change Guide

What You’ll Need

• Full‑synthetic 0W‑20 oil (≈5 quarts)
• New oil filter (OEM or high‑quality aftermarket)
• Oil drain pan, funnel, socket set, and wrench
• Shop rags and a torque wrench (optional but recommended)

Procedure

1. Prepare the Car – Park on a level surface, engage the parking brake, and let the engine cool for a few minutes. Raise the front with a jack and secure it on stands.

2. Drain the Old Oil – Position the drain pan, remove the drain plug, and let the oil flow out completely. This usually takes 5–7 minutes.

3. Replace the Filter – Use the filter wrench to unscrew the old filter. Before installing the new one, dab a little fresh oil on the rubber seal; this ensures a proper seal and easier removal later.

4. Reinstall the Drain Plug – Torque the plug to the manufacturer’s specification (usually around 30 lb‑ft). Over‑tightening can strip the threads.

5. Fill with New Oil – Using a funnel, pour the 0W‑20 oil into the fill hole. Start with 4.8 quarts, then check the dipstick. Add small amounts until the level is just below the “MAX” mark.

6. Run the Engine – Start the car and let it idle for a minute. This circulates oil and allows the filter to pressurize. Re‑check the level and adjust if needed.

Common Oil‑Related Issues to Watch For

Even with the right oil, problems can arise. A ticking noise from the top end may signal low oil pressure, while a sudden drop in fuel economy could indicate oil that’s too thick for the engine’s design. If you notice blue‑gray smoke from the exhaust, it could be oil burning—often a sign of worn piston rings or valve guides.

Regularly inspecting the oil’s color and consistency helps catch these issues early. Dark, gritty oil suggests contaminants, while a thin, watery appearance could mean a coolant leak.

Cost Considerations

Expect to pay between $45 and $70 for a full synthetic 0W‑20 change at a reputable shop, including the filter. Doing it yourself can shave that cost down to $25‑$35 for oil and filter, plus the modest price of tools if you don’t already own them. The savings, however, come with the responsibility of proper disposal of used oil—most auto parts stores accept it for recycling.

FAQ

What oil viscosity should I use in a 2019 Nissan Maxima?

The recommended viscosity is 0W‑20 full synthetic, as specified in the owner’s manual.

How often does the oil need to be changed?

With synthetic oil, aim for every 5,000‑7,500 miles, or follow the oil life indicator on the dashboard.

Is conventional oil ever acceptable?

It’s not recommended for long‑term use because it can increase wear and reduce fuel efficiency. Stick with synthetic 0W‑20 for optimal performance.

What are the signs of low oil or oil problems?

Look for a low dipstick reading, engine ticking, excessive smoke, or a sudden drop in fuel economy.
