Every car has unique engine oil requirements based on design, performance demands, and manufacturer specifications. The 2017 Hyundai Sonata is no exception. This midsize sedan was designed with efficiency and reliability in mind, and Hyundai engineered its engines to perform best with specific oil formulations and capacities.

The 2017 Sonata comes with two primary engine options: the naturally aspirated 2.4-liter inline-four (often labeled as the “Theta II” engine) and the more powerful 2.0-liter turbocharged four-cylinder (the “Gamma II T-GDi”). Despite their differences in power output and technology, both engines share the same oil capacity of **4.8 quarts (4.5 liters)** when the oil filter is replaced. This includes approximately 4.5 quarts of oil in the engine sump and about 0.3 quarts held in the new oil filter.

It’s important to note that this capacity assumes a complete oil change—draining all the old oil and installing a fresh filter. If you’re topping off oil between changes, you’ll only need to add what’s missing, which is typically much less than a full quart. Overfilling can be just as harmful as underfilling, so always check the dipstick after adding oil.

Hyundai designed these engines to operate efficiently with modern synthetic oils, which offer better thermal stability, improved fuel economy, and longer service life compared to conventional oils. The manufacturer recommends using **full synthetic oil** with a viscosity of **5W-20 or 0W-20**, depending on your climate and driving conditions. We’ll dive deeper into oil types in the next section, but for now, remember that using the correct oil is just as important as using the right amount.

Why Oil Capacity Matters

You might be wondering, “Why does oil capacity matter so much?” After all, isn’t oil just oil? The truth is, engine oil plays multiple critical roles, and having the correct amount ensures each function is performed effectively.

First, oil lubricates the engine’s moving parts—pistons, crankshafts, camshafts, and valves. Without enough oil, these components can grind against each other, causing excessive wear and heat. Second, oil helps cool the engine by carrying heat away from hot spots. Third, it cleans the engine by suspending dirt, metal particles, and combustion byproducts, which are then trapped by the oil filter. Finally, oil creates a seal between piston rings and cylinder walls, improving compression and efficiency.

If your Sonata doesn’t have enough oil, these functions are compromised. Low oil levels can lead to increased friction, overheating, and eventually engine seizure. On the flip side, overfilling can cause oil to foam, reducing its lubricating properties and potentially damaging seals and gaskets. That’s why precision matters—4.8 quarts is the sweet spot for your 2017 Sonata.

Engine Variations and Oil Requirements

While both the 2.4L and 2.0L turbo engines in the 2017 Sonata take the same amount of oil, there are some nuances to consider. The turbocharged engine operates under higher temperatures and pressures due to forced induction. This means it may benefit slightly more from the enhanced protection of full synthetic oil, especially in hot climates or during spirited driving.

Additionally, turbo engines can be more sensitive to oil degradation. Sludge buildup is a common issue in turbocharged engines if oil changes are delayed or low-quality oil is used. Therefore, sticking to Hyundai’s recommended oil change interval—every 7,500 miles or 12 months—is even more critical for the 2.0L turbo model.

That said, both engines are designed to meet modern emissions and efficiency standards, and Hyundai has engineered them to work reliably with the same oil capacity and type. As long as you follow the maintenance schedule and use the correct oil, either engine should provide years of trouble-free service.

Choosing the right oil for your 2017 Hyundai Sonata isn’t just about picking any bottle off the shelf. Hyundai provides specific recommendations based on engine design, climate, and performance expectations. Using the wrong oil can void your warranty, reduce fuel economy, and even damage your engine over time.

The manufacturer recommends using **full synthetic engine oil** with a viscosity of **5W-20 or 0W-20**. Let’s break down what that means and why it matters.

Understanding Oil Viscosity: 5W-20 vs. 0W-20

Oil viscosity refers to how thick or thin the oil is. The “W” stands for “winter,” indicating how the oil performs in cold temperatures. The first number (5W or 0W) tells you the oil’s flowability when cold—lower numbers mean the oil flows more easily in cold weather. The second number (20) indicates the oil’s thickness at operating temperature.

For most drivers in moderate to cold climates, **5W-20** is the standard recommendation. It provides excellent cold-start protection and maintains proper lubrication once the engine warms up. However, in extremely cold regions (below 0°F or -18°C), **0W-20** may be preferred because it flows even more easily at startup, reducing engine wear during those critical first moments.

Both viscosities are approved by Hyundai for the 2017 Sonata, so you can choose based on your local weather. If you live in a place with harsh winters, 0W-20 might offer a slight advantage. In warmer climates, 5W-20 is perfectly suitable.

Why Full Synthetic Oil?

Hyundai specifies full synthetic oil for a reason. Unlike conventional mineral oil, synthetic oil is engineered at the molecular level to provide superior performance. It offers better resistance to breakdown under high heat, improved flow in cold temperatures, and longer service life.

Full synthetic oil also contains fewer impurities, which means it’s less likely to form sludge or varnish inside your engine. This is especially important for modern engines like those in the 2017 Sonata, which have tight tolerances and advanced fuel injection systems.

While synthetic oil is more expensive than conventional oil, the benefits far outweigh the cost. You’ll likely go longer between changes, experience better fuel economy, and protect your engine more effectively. Plus, many synthetic oils are now priced competitively, making them accessible for most drivers.

API and ILSAC Certifications

When shopping for oil, look for bottles that meet **API (American Petroleum Institute)** and **ILSAC (International Lubricant Standardization and Approval Committee)** standards. For the 2017 Sonata, Hyundai recommends oils that meet **API SN or later** and **ILSAC GF-5 or later** specifications.

These certifications ensure the oil has been tested for performance, emissions compatibility, and engine protection. You’ll usually see these labels on the front or back of the oil container. Using certified oil gives you peace of mind that you’re meeting Hyundai’s requirements.

Top Oil Brands for Your Sonata

While Hyundai doesn’t endorse specific brands, many high-quality synthetic oils work well in the 2017 Sonata. Some popular and reliable options include:

– **Mobil 1 Extended Performance 5W-20 or 0W-20**
– **Castrol EDGE Full Synthetic 5W-20**
– **Pennzoil Platinum Full Synthetic 5W-20**
– **Valvoline Full Synthetic 5W-20**
– **Hyundai Genuine Motor Oil (available at dealerships)**

These brands meet or exceed Hyundai’s specifications and are widely available at auto parts stores, dealerships, and online. If you prefer to stick with OEM (original equipment manufacturer) products, Hyundai’s own motor oil is formulated specifically for their engines and is a safe choice.

Performing your own oil change can save you money and give you greater control over your vehicle’s maintenance. With the right tools and a bit of know-how, changing the oil in your 2017 Hyundai Sonata is a straightforward process.

Tools and Supplies You’ll Need

Before you begin, gather the following items:

– 4.8 quarts of full synthetic 5W-20 or 0W-20 oil
– New oil filter (Hyundai part #26300-35503 or equivalent)
– Oil filter wrench (if the filter is tight)
– Socket wrench with 17mm socket (for drain plug)
– Oil drain pan (at least 6-quart capacity)
– Funnel
– Jack and jack stands or ramps (for access)
– Gloves and safety glasses
– Rags or paper towels

Make sure your car is on level ground and the engine is cool but not cold—ideally, after a short drive. This helps the oil flow more easily during draining.

Step-by-Step Oil Change Guide

1. **Lift the Vehicle:** Use a jack and jack stands or drive onto ramps to safely lift the front of the car. Never work under a vehicle supported only by a jack.

2. **Locate the Drain Plug:** Underneath the engine, find the oil pan and the 17mm drain plug. Place the drain pan directly beneath it.

3. **Drain the Old Oil:** Loosen the drain plug with a socket wrench and carefully remove it by hand. Allow the oil to drain completely—this may take 5–10 minutes. Be careful, as the oil may still be warm.

4. **Replace the Drain Plug:** Once drained, clean the drain plug and reinstall it. Tighten it to the manufacturer’s torque specification (typically 25–30 ft-lbs). Do not overtighten.

5. **Remove the Old Oil Filter:** Use an oil filter wrench if needed. Turn the old filter counterclockwise to remove it. Before installing the new filter, apply a thin layer of fresh oil to the rubber gasket on the new filter to ensure a proper seal.

6. **Install the New Filter:** Screw the new filter on by hand until it seats, then give it an additional ¾ turn. Do not overtighten.

7. **Add New Oil:** Locate the oil filler cap on top of the engine. Insert a funnel and pour in approximately 4.5 quarts of oil. Wait a few minutes for the oil to settle, then check the level with the dipstick.

8. **Check the Oil Level:** Wipe the dipstick clean, reinsert it fully, then pull it out again. The oil should be between the “L” (low) and “F” (full) marks. Add more oil if needed, but avoid overfilling.

9. **Start the Engine:** Run the engine for 10–15 seconds to circulate the new oil, then turn it off and recheck the level. Top off if necessary.

10. **Dispose of Used Oil Properly:** Pour used oil into a sealed container and take it to a recycling center or auto parts store that accepts used oil.

Tips for a Successful Oil Change

– Always replace the oil filter—even if you’re only topping off oil, a new filter ensures clean circulation.
– Use a torque wrench for the drain plug to avoid stripping the threads.
– Keep a record of your oil changes, including date, mileage, and oil type used.
– If you’re unsure about any step, consult your owner’s manual or seek professional help.

Oil Change Intervals and Maintenance Schedule

Hyundai recommends changing the oil in your 2017 Sonata every **7,500 miles or 12 months**, whichever comes first, under normal driving conditions. This interval is based on the use of full synthetic oil and typical city/highway driving.

However, if you frequently drive in severe conditions—such as stop-and-go traffic, extreme temperatures, towing, or short trips—you may need to change the oil more often, such as every 5,000 miles. Your owner’s manual includes a “severe driving” schedule for these situations.

Modern engines and synthetic oils allow for longer intervals, but it’s still important to monitor oil level and condition regularly. Check the dipstick every few weeks or before long trips. If the oil looks dark, gritty, or low, it’s time for a change—even if you haven’t hit the mileage limit.

Environmental and Safety Considerations

Proper oil disposal is crucial for protecting the environment. Used motor oil can contaminate soil and water if not handled correctly. Never pour oil down drains, on the ground, or into storm sewers.

Most auto parts stores and service centers accept used oil and filters for recycling. Many communities also host hazardous waste collection events. Recycling one gallon of used oil can produce enough energy to power a home for 24 hours—so it’s worth the effort.

Always wear gloves and safety glasses when handling oil to avoid skin contact and eye irritation. Work in a well-ventilated area, and clean up any spills immediately.

Conclusion

The 2017 Hyundai Sonata takes **4.8 quarts of full synthetic oil** (5W-20 or 0W-20) with a new filter. Following the recommended oil type, capacity, and change interval ensures your engine stays protected, efficient, and reliable. Whether you change the oil yourself or visit a service center, staying on top of this simple maintenance task can extend the life of your Sonata and save you money in the long run. Regular oil checks, proper disposal, and using quality products are all part of responsible car ownership. With the right care, your Sonata will continue to deliver a smooth, quiet, and enjoyable driving experience for many miles to come.
