What Kind of Oil a 2015 Hyundai Azera Takes

The 2015 Hyundai Azera is specified to use **SAE 5W-20 or 5W-30, full synthetic or synthetic-blend engine oil that meets API SM (or higher) and ILSAC GF-4 (or higher) standards**, with a typical capacity of about **5 to 6 quarts** depending on engine and whether the filter is changed. Below is a detailed breakdown of the official recommendations, capacity, and practical tips to keep the Azera’s 3.3‑liter V6 running reliably.

Official Oil Specifications for the 2015 Hyundai Azera

The 2015 Hyundai Azera sold in North America is equipped with a 3.3‑liter V6 gasoline engine. Hyundai’s own documentation outlines the oil viscosity grades and quality standards owners should follow to protect the engine, maintain efficiency, and keep the warranty valid.

Recommended Oil Viscosity

Viscosity describes how thick or thin engine oil is at different temperatures. For the 2015 Azera, Hyundai specifies viscosity grades suitable for a wide range of climates.

The following list explains the manufacturer-approved viscosity options for normal driving conditions:

• SAE 5W-20 – Commonly recommended for fuel efficiency in many Hyundai gasoline engines.
• SAE 5W-30 – Also acceptable and often preferred in hotter climates or for drivers who put the engine under heavier load.

Both 5W‑20 and 5W‑30 are compatible with the Azera’s engine; the best choice often comes down to climate and personal preference within Hyundai’s guidelines.

Oil Type and Quality Standards

Beyond viscosity, it is crucial that engine oil meets specific quality ratings set by major standards organizations. This ensures the oil has the right detergents, anti‑wear additives, and stability.

The following list details the main specifications you should look for on the oil container label:

• API rating: At least API SM (or “SN,” “SP” and later, which are backward compatible and superior).
• ILSAC standard: At least ILSAC GF-4 (GF‑5 and GF‑6 are newer and also acceptable or better).
• Oil type: Full synthetic or synthetic blend is strongly recommended for modern Hyundai engines for better protection and stability.

If the bottle shows “For gasoline engines” and lists API SM/SN/SP and ILSAC GF‑4/5/6, it generally meets or exceeds Hyundai’s requirements for the 2015 Azera.

Oil Capacity for the 2015 Hyundai Azera

Knowing how much oil the engine holds is essential when doing an oil change, especially if you are servicing the vehicle yourself. Overfilling or underfilling can cause engine problems.

Engine Oil Capacity With and Without Filter

The 2015 Hyundai Azera’s 3.3‑liter V6 has a relatively standard capacity for a mid‑size sedan. The exact quantity can vary slightly depending on how thoroughly the old oil drains and whether the oil filter is replaced.

The following list outlines typical oil capacities for the 2015 Azera’s 3.3‑liter V6 engine:

• With filter change: Approximately 5.5–6.0 US quarts (about 5.2–5.7 liters).
• Without filter change: Slightly less, typically about 0.3–0.5 quart less than the “with filter” capacity.
• Practical approach: Add about 5 quarts, run the engine briefly, then top off gradually while checking the dipstick until the level is in the “Full” range.

Because pan design, drain time, and filter brand can affect the exact amount, always use the dipstick as the final check rather than relying solely on a fixed number.

How to Choose Between 5W‑20 and 5W‑30

While both 5W‑20 and 5W‑30 are approved viscosities, certain conditions may make one preferable over the other. The decision mainly depends on climate, driving style, and personal maintenance priorities.

Climate and Driving Conditions

Hyundai calibrates its engines to work across diverse climates, but oil behavior changes with temperature. Choosing the right viscosity can improve start‑up protection and efficiency.

The following list outlines general guidance for selecting between 5W‑20 and 5W‑30 for a 2015 Azera:

• Colder climates (frequent freezing temperatures): 5W‑20 offers slightly easier cold starts and marginally better fuel economy.
• Hotter climates or heavy use: 5W‑30 provides a bit more film strength at high operating temperatures, which some owners prefer for highway driving, hills, or heavy loads.
• Mixed or moderate climates: Either 5W‑20 or 5W‑30 is suitable; many owners simply follow what their dealer or original factory fill used.

For most drivers in typical U.S. conditions, using either grade that meets current API and ILSAC specs will protect the engine effectively.

Fuel Economy vs. Engine Protection

Automakers often specify lower‑viscosity oil partly for fuel‑economy targets, while some owners prioritize maximum protection, especially as the vehicle ages.

The following list summarizes the trade‑offs the average Azera owner might consider:

• 5W‑20: Slightly better fuel economy and quick flow at cold start, aligned with many OEM efficiency goals.
• 5W‑30: Slightly thicker at operating temperature, which can provide additional high‑temperature protection, especially in older or high‑mileage engines.
• Owner practice: Some owners start with 5W‑20 when the car is newer, then move to 5W‑30 as mileage climbs past 100,000 miles, while staying within Hyundai’s approved range.

In practice, as long as the oil is changed on time and meets or exceeds Hyundai’s standards, both approved grades perform well in the 2015 Azera.

Oil Change Intervals and Maintenance Tips

Choosing the right oil is only part of the equation; using it for an appropriate interval and monitoring engine condition are just as important. Modern oils last longer, but driving patterns still heavily influence change intervals.

Recommended Change Intervals

Hyundai historically has offered two maintenance schedules: “normal” and “severe.” Many real‑world driving patterns actually fall under “severe,” even if owners don’t realize it.

The following list describes typical guidelines for changing oil in a 2015 Hyundai Azera (always confirm with the latest Hyundai maintenance schedule or dealer):

• Normal driving: Around 7,500 miles or about 12 months, whichever comes first, when using quality synthetic oil.
• Severe driving: Around 3,750–5,000 miles, especially if you frequently drive short trips, in heavy traffic, high heat, dusty conditions, or with long idling.
• High‑mileage vehicles: Many owners of older Azeras voluntarily shorten intervals to 5,000 miles to mitigate wear and sludge risk.

Adjusting your oil change schedule to your actual driving conditions is usually more important than debating minor differences between oil brands.

Choosing a Brand and Oil Filter

Hyundai does not require a specific brand of oil, but quality and proper filtration matter, especially for engines designed with narrow oil passages and variable valve timing systems.

The following list provides practical advice on oil brands and filters for a 2015 Azera:

• Oil brands: Any major name brand (e.g., Mobil 1, Castrol, Pennzoil, Valvoline, Shell, etc.) that meets API and ILSAC specs is acceptable.
• Hyundai or OEM‑equivalent filters: Using genuine Hyundai filters or high‑quality aftermarket equivalents helps maintain proper oil pressure and filtration.
• Avoid ultra‑cheap filters: Low‑quality filters may have poor internal construction, weak bypass valves, or limited filtration area, which can affect engine longevity.

Consistency—using quality oil and filters and changing them on time—usually has a bigger impact than the specific brand you choose, as long as it meets the standards.

How to Verify the Correct Oil for Your Specific Azera

Although the general specifications above apply to the 2015 Hyundai Azera with the common 3.3‑liter V6, it is always wise to confirm against the exact vehicle and region, as markets outside North America can vary in recommendations.

Owner’s Manual and Under‑Hood Labels

The most authoritative source remains your vehicle’s own documentation and labeling. Regional differences, updates, or special equipment may lead to slight variations.

The following list shows where to confirm the oil specification for your particular car:

• Owner’s manual: Check the “Specifications” or “Maintenance” section for viscosity chart and capacity figures specific to the 2015 Azera.
• Oil filler cap: Many Hyundai models have the recommended viscosity (e.g., “5W‑20”) printed directly on the cap.
• Dealer or Hyundai service portal: Dealers can reference the latest technical bulletins and regional recommendations if anything has changed since publication of the manual.

Spending a few minutes confirming the manual or filler‑cap notation helps avoid relying on generic parts-store databases, which can occasionally list outdated or incomplete information.

Summary

The 2015 Hyundai Azera is designed to run on **SAE 5W‑20 or 5W‑30 engine oil** that meets at least **API SM (or newer SM/SN/SP)** and **ILSAC GF‑4 (or newer GF‑5/GF‑6)** standards, with a typical capacity of about **5.5–6.0 quarts including the filter**. Using a reputable full synthetic or synthetic‑blend oil and a quality filter, and changing them at **5,000–7,500‑mile intervals** depending on driving conditions, will help keep the Azera’s 3.3‑liter V6 smooth, efficient, and reliable for the long term.

What type of oil does a Hyundai Azera take?

The Hyundai Azera requires either 5W-20 or 5W-30 motor oil, depending on the model year. For a 2009 model, 5W-20 is preferred, while 5W-30 is recommended for models from 2012-2017. It is best to use a fully synthetic oil to ensure the best performance and protection. 
Oil type by model year

• 2006: 5W-20
• 2007: 5W-20
• 2009: 5W-20 is preferred
• 2012–2017: 5W-30 

Choosing the right oil

• Full synthetic: This is the recommended type for the best performance and protection. 
• High-mileage oil: If your car has over 75,000 miles, you can consider using a high-mileage oil, which is designed to help older engines with leaks and seals. 
• Conventional oil: While some models can use conventional oil, full synthetic is generally the better choice. 

Other considerations

• Oil capacity: The capacity varies by model. For example, the 2009 Azera takes 5.5 quarts with a filter, while the 2017 model takes 6 quarts with a filter. 
• Oil filter: Always remember to change the oil filter with the oil.
• Consult your owner’s manual: For the most accurate information, always check your specific owner’s manual. 

What oil does a 2015 Hyundai Azera take?

The correct oil for a 2015 Hyundai Azera is 5W-30 full synthetic motor oil, which is also the preferred viscosity for all temperatures. The engine requires 6 quarts of oil when changing the filter. 

• Oil Type: 5W-30 full synthetic motor oil is recommended. 
• Capacity: The engine requires 6 quarts of oil, including the filter. 
• Benefits: Full synthetic oil provides the best protection against wear, oxidation, and sludge. 

Can I use 5W-30 instead of 5W20 in my Hyundai?

Yes, you can likely use 5W-30 instead of 5W-20, as many Hyundai models are compatible with both, but you should always check your owner’s manual first for the definitive recommendation. Using 5W-30 may result in slightly lower fuel economy and can be better for engine longevity in older, higher-mileage engines, while 5W-20 is optimized for fuel efficiency. 
Before you make the switch

• Check your owner’s manual: This is the most important step, as it will have the exact specification for your specific engine and vehicle. The engine oil cap may also have this information printed on it. 
• Consider the benefits:
  • 5W-20: Offers better fuel economy because it is a thinner oil, which reduces friction. 
  • 5W-30: Can provide better protection, especially in older or high-mileage engines where internal parts may be slightly looser. It may also run quieter. 

Potential downsides of using 5W-30

• Reduced fuel economy: The thicker oil requires the engine to work slightly harder, which can decrease your miles per gallon. 
• Slightly poorer cold starts: The oil may not flow as easily when the engine is cold, although the difference is minor with a 5W viscosity rating. 
• Engine drag: Some users report that the engine feels less responsive with the thicker oil. 

Final recommendation

• For optimal performance and fuel efficiency, stick with the manufacturer’s recommendation of 5W-20 if your manual specifies it. 
• If your manual lists both 5W-20 and 5W-30 as acceptable options, either will work, and the choice depends on whether you prioritize fuel economy or slightly more protection. 
• If you’ve accidentally put 5W-30 in a car that calls for 5W-20, it’s generally not an emergency, but you should use the correct 5W-20 oil at your next oil change.
