The 2015 Hyundai Sonata SE, which typically uses the 2.4-liter inline-4 engine, requires about 5.0 quarts of engine oil (including a replaceable filter) for a full oil change. This amount can vary slightly by engine variant or service procedure, so always confirm against the owner's manual or Hyundai service data for your VIN.
The question concerns the exact oil capacity of the Sonata SE for its maintenance, and there are a few engine options across the 2015 lineup. The SE is most commonly equipped with the 2.4L engine, but other trims offer different powerplants, which change the oil capacity by a quart or so. This article lays out the standard capacity and notes where to check for differences.
Oil capacity by engine option
These figures reflect typical factory specifications for the 2015 Sonata lineup, with the SE most often using the 2.4L engine. If your car has a different engine, use its specific capacity to avoid over- or underfilling.
- 2.4L I4 (Theta II) engine: 5.0 quarts (with filter) ≈ 4.7 liters
- 2.0L turbo I4 (2.0T) engine, available in some trims: about 5.5–5.8 quarts (with filter)
Note: Always verify exact capacity for your vehicle’s VIN, as production changes or different oil filter sizes can affect the total. If in doubt, drain the old oil completely, replace the filter, and refill to the recommended level using the dipstick as a guide.
Oil type and maintenance intervals
Along with capacity, the type of oil and how often you should change it are important for engine longevity. Hyundai's 2.4L engine commonly calls for synthetic oil in the 5W-20 or 5W-30 range depending on climate and service data. The standard maintenance interval for synthetic oil in many vehicles is around 7,500 to 10,000 miles, but severe driving conditions or an older model may require more frequent changes. Always follow the owner's manual or dealer guidance for your vehicle's specific interval and oil grade.
Recommended oil grade and change tips
- Oil grade: Synthetic 5W-20 or 5W-30 as specified for your climate and VIN
- Change interval: Typically 7,500–10,000 miles with synthetic oil, shorter if driving under severe conditions
Conclusion: For an oil change on a 2015 Sonata SE with the 2.4L engine, plan to use about 5 quarts of oil with a new filter, and confirm exact capacity and grade with the owner's manual or a Hyundai service bulletin linked to your VIN.
Summary
The 2015 Hyundai Sonata SE typically uses 5.0 quarts of engine oil with a filter for the 2.4L engine. Always verify the precise capacity and oil specification for your VIN in the owner's manual or with a Hyundai dealer, as variations exist between engines and production runs. Regular oil changes with the recommended grade help keep the engine running smoothly.
