Engine oil is one of the most important components in a vehicle’s engine, as it serves multiple functions such as lubricating moving parts, reducing friction, and preventing wear and tear. In addition to these functions, engine oil also helps regulate engine temperature and improves fuel efficiency. Therefore, it is important to understand the recommended engine oil type and maintenance intervals for the 2018 Hyundai Sonata to ensure optimal engine performance and longevity.
What Type Of Oil Does My 2018 Hyundai Sonata Take?
The 2018 Hyundai Sonata requires different engine oils depending on the engine type. The 1.6/2.0 T-GDI engines require an SAE viscosity grade of 5W-30 or 5W-40, with an API SM / ILSAC GF-4 / ACEA A5 or above oil specification. For better fuel economy, it is recommended to use engine oil of a viscosity grade 5W-30. The 2.4 GDI engine, on the other hand, requires an SAE viscosity grade of 5W-20 or 5W-30, with an API SM / ILSAC GF-4 oil specification. For better fuel economy, it is recommended to use engine oil of a viscosity grade SAE 5W-20.
2018 Hyundai Sonata SE Oil Type
The recommended engine oil for the 2018 Hyundai Sonata SE with the 2.4L GDI engine is a viscosity grade of 5W-20, which meets the API SM / ILSAC GF-4 specifications for better fuel economy. It is important to choose an engine oil that matches the temperature range of where the vehicle will be operated. This engine requires 5.07 US qt. (4.8 L) of oil for a drain and refill. It is essential to ensure the oil meets the recommended specifications to avoid engine damage and maintain optimal performance.
How Much Oil Does A 2018 Hyundai Sonata Take?
The engine oil capacity for the 2018 Hyundai Sonata is dependent on the specific engine model.
The 1.6 T-GDI engine has an oil capacity of 4.75 US qt. (4.5 L), while the 2.0 T-GDI and 2.4 GDI engines have an oil capacity of 5.07 US qt. (4.8 L). These quantities represent the recommended amount for a drain and refill of engine oil. It is important not to overfill the engine oil, as this can lead to engine damage.
Service Interval
The recommended service interval for the 2018 Hyundai Sonata is every 7,500 miles or 12 months, whichever comes first. However, under certain driving conditions such as frequent short trips, extreme temperatures, or dusty environments, it is recommended to change the oil more frequently.
It is important to follow the maintenance schedule in the owner’s manual to ensure optimal performance and longevity of the engine. Neglecting to change the oil at the recommended intervals can lead to engine damage and costly repairs.
How to Check the Engine Oil Level
To check the engine oil level in the 2018 Hyundai Sonata, follow these steps:
- Park the vehicle on a level surface and turn off the engine.
- Wait a few minutes to allow the oil to settle in the oil pan.
- Open the hood and locate the engine oil dipstick.
- Pull the dipstick out and wipe it clean with a lint-free cloth or paper towel.
- Reinsert the dipstick all the way back in, making sure it is fully seated.
- Pull the dipstick out again and check the oil level. It should be between the two marks on the dipstick.
- If the oil level is low, add the recommended engine oil until it reaches the proper level. Avoid overfilling the engine.
It is important to clean the area around the dipstick before checking the oil to prevent dirt and grit from entering the engine. Also, check the oil level regularly, at least once a month, to ensure proper engine lubrication and prevent engine damage.
Additional Maintenance Steps
When performing maintenance on the Sonata’s engine, it’s important to not only change the oil at the recommended intervals but also inspect other components to ensure optimal performance.
One important component to check is the air cleaner filter. This should be inspected periodically and replaced if it is dirty or damaged. A dirty air filter can restrict air flow to the engine and decrease fuel economy.
In addition, fuel additives can be added to the gas tank to help clean fuel injectors and prevent build-up of carbon deposits in the engine. It’s important to use fuel additives recommended by Hyundai and to follow the recommended usage instructions.
It’s also recommended to inspect the intercooler, in/out hose, and air intake hose every 10,000 km on the turbocharged engines to ensure they are free of debris and in good condition.
By performing these additional maintenance steps, you can help ensure that your Sonata’s engine is operating at its best and maximizing its lifespan.
Does 2018 Hyundai Sonata Use Synthetic Oil?
The 2018 Hyundai Sonata can use synthetic engine oil that meets the recommended specifications. However, it is not required to use synthetic oil and conventional engine oil that meets the recommended specifications can also be used.
Conclusion
In conclusion, using the proper engine oil and adhering to recommended service intervals are crucial for the performance and longevity of the 2018 Hyundai Sonata’s engine. It is important to check the engine oil level regularly and follow recommended maintenance steps such as inspecting the air cleaner filter and adding fuel additives. By taking these steps, drivers can ensure their Sonata runs smoothly and reliably for years to come.
