Whether you’re a new Infiniti owner or a long-time fan, this article will help you maintain your Q50 with confidence.
Why Oil Capacity Matters For Infiniti Q50
The engine oil capacity is not just a technical number. It is the total amount of oil your engine needs to operate safely and efficiently. Too little oil means parts may rub together, causing heat and wear. Too much oil can create foam, reduce lubrication, and even damage your catalytic converter.
Every engine is built with a specific oil capacity for good reasons:
- Proper lubrication: Ensures all moving parts are covered by a thin film of oil.
- Cooling: Oil helps take heat away from the engine.
- Cleaning: Oil picks up dirt and carries it to the oil filter.
- Protection: The right amount of oil prevents corrosion and excessive wear.
Infiniti Q50 models come with different engines – from the 2. 0L turbo to the 3. 0L twin-turbo V6, and even a hybrid variant. Each has a unique oil capacity, so using the right number is critical for your car’s health.

How To Check And Change Infiniti Q50 Oil
Changing your engine oil is one of the easiest ways to extend the life of your Infiniti Q50. Here’s how to do it right:
Step 1: Gather Supplies
You’ll need:
- The right amount and type of engine oil (check your owner’s manual for the exact viscosity, usually 0W-20 or 5W-30 for most Q50s)
- A new oil filter
- A wrench, oil drain pan, and funnel
- Gloves and rags
Step 2: Warm Up The Engine
Run your car for a few minutes. Warm oil drains faster and carries more debris out.
Step 3: Drain Old Oil
Turn off the engine. Place the drain pan under the oil pan. Remove the drain plug and let the oil flow out.
Step 4: Replace The Oil Filter
Unscrew the old filter. Lightly oil the gasket on the new filter, then screw it on by hand.
Step 5: Add New Oil
Put the drain plug back. Pour in the new oil, using the correct oil capacity for your Q50. Avoid overfilling.
Step 6: Check Oil Level
Start the engine and let it run for a minute. Stop the engine, wait a few minutes, then check the dipstick. Top off if needed.
Step 7: Dispose Of Old Oil
Never dump used oil. Take it to a recycling center.
Practical Tips
- Always change the filter when you change the oil.
- Use a torque wrench to tighten the drain plug to the manufacturer’s spec.
- Don’t guess the oil type; check your manual.
- After filling, check for leaks under the car.
Infiniti Q50 Oil Capacity: Year And Engine Matrix
For even more clarity, here’s a matrix summarizing the main engines and oil capacities by year:
| Model Year | Engine Option | Oil Capacity (quarts/liters) |
|---|---|---|
| 2014-2015 | 3.7L V6 (all trims) | 5.2 / 4.9 |
| 2014-2018 | 3.5L Hybrid V6 | 5.2 / 4.9 |
| 2016-2019 | 2.0L Turbo I4 | 5.1 / 4.8 |
| 2016-2022 | 3.0L Twin-Turbo V6 (all trims) | 5.1 / 4.8 |
Choosing The Right Oil For Your Infiniti Q50
Oil capacity is only part of the story. You must also use the correct oil type and viscosity.
- Most Q50s need full synthetic oil for best performance.
- For 3.0L and 2.0L engines, Nissan recommends 0W-20 synthetic.
- The older 3.7L and hybrid 3.5L engines often use 5W-30 synthetic.
- Never mix viscosities or use regular (non-synthetic) oil unless it’s an emergency.
Why Oil Type Matters
Using the wrong oil can cause:
- Poor lubrication
- Hard starting in cold weather
- Reduced fuel economy
- Increased engine wear
Always check your owner’s manual or speak to a certified Infiniti technician for the latest recommendations.
Common Oil Change Mistakes (and How To Avoid Them)
- Overfilling or underfilling: Always measure oil as you fill, and check the dipstick. Too much or too little oil can harm your engine.
- Wrong oil type: Even experienced owners sometimes use the wrong viscosity, especially after switching brands.
- Old oil filter: Reusing or skipping the filter change reduces oil flow and protection.
- Not tightening drain plug enough: Leads to leaks. Always use a torque wrench if possible.
- Forgetting to reset the oil change light: After changing oil, reset the maintenance reminder in your car’s computer.
Oil Change Intervals For Infiniti Q50
Infiniti recommends changing oil every 5,000 to 7,500 miles (8,000 to 12,000 km) or at least once a year. For severe use (frequent short trips, heavy traffic, extreme hot or cold), change more often.
Signs You Need An Oil Change
- Oil looks dark or dirty on the dipstick
- Engine runs louder than usual
- Oil change light is on
- You smell burning oil
Two Key Insights Most Infiniti Q50 Owners Miss
- Oil capacity can change with a small engine update or even a new oil pan design. Always double-check your specific year and engine, even if you think you already know the number.
- Hybrid models often run the engine less, but their oil still ages and breaks down. Don’t skip oil changes just because you drive a hybrid—change oil by time as well as distance.
Should You Use High Mileage Or Synthetic Oil?
If your Q50 has over 75,000 miles (120,000 km), some owners use high-mileage synthetic oil. These oils have additives that help older engines stay sealed and reduce leaks. For most Q50s, full synthetic is best—unless your engine is burning oil, then high-mileage oil is a smart option.
Can You Change Infiniti Q50 Oil Yourself?
Many Q50 owners do their own oil changes. The process is straightforward, but you need the right tools and a safe way to lift the car if needed. If you’re unsure, a professional oil change costs more but saves time and risk.
Infiniti Q50 Oil Capacity: Quick Reference Table
Here is a quick lookup for the latest Q50 models:
| Year | Engine | Capacity (quarts/liters) | Recommended Oil |
|---|---|---|---|
| 2022 | 3.0L Twin-Turbo V6 | 5.1 / 4.8 | 0W-20 Full Synthetic |
| 2021 | 3.0L Twin-Turbo V6 | 5.1 / 4.8 | 0W-20 Full Synthetic |

| 2018 | 3.5L Hybrid V6 | 5.2 / 4.9 | 5W-30 Full Synthetic |
Expert Tips For Infiniti Q50 Oil Maintenance
- Check oil level monthly: Engines can burn small amounts of oil between changes.
- Inspect for leaks: Small oil leaks are easier and cheaper to fix early.
- Stick to genuine filters: Cheap filters may not seal well or filter as effectively.
- Keep oil receipts: If your engine ever has a problem under warranty, proof of oil changes is required.
- Use a quality funnel: This helps avoid spills when adding oil.

Frequently Asked Questions
How Often Should I Change Oil In My Infiniti Q50?
You should change the oil every 5,000 to 7,500 miles (8,000 to 12,000 km) or at least once a year. If you drive in tough conditions, change it more often.
What Is The Oil Capacity For A 2017 Infiniti Q50 3.0l Twin-turbo?
The oil capacity is 5.1 quarts (4.8 liters) including the filter.
Can I Use 5w-30 Oil Instead Of 0w-20 In My Q50?

What Happens If I Overfill The Oil In My Infiniti Q50?
Too much oil can create foam, reduce lubrication, and damage your engine. Always fill to the recommended level and check with the dipstick.
Does The Infiniti Q50 Hybrid Need Oil Changes As Often As Regular Models?
Yes. Even though the engine may run less, the oil still breaks down over time. Follow the same oil change intervals as non-hybrid models.
Taking care of your Infiniti Q50’s oil capacity needs is simple but critical for long engine life and top performance. With the right oil, correct amount, and careful attention to detail, your Q50 will reward you with years of reliable driving. If you ever have doubts, check your manual or speak with an Infiniti technician to make sure you’re giving your car exactly what it needs.
