The 2017 Hyundai Elantra typically requires SAE 0W-20 synthetic motor oil. This is the standard recommendation for the 2.0-liter engine used in most trims and is designed to support fuel economy and engine protection.
This article explains the official oil grade, acceptable alternatives, and practical guidance for maintaining your Elantra’s engine oil, including climate considerations and maintenance reminders.
Official oil grade and specifications
Here are the essential specifications and options most relevant to a 2017 Elantra.
- Oil type: Synthetic motor oil (fully synthetic) is preferred; it provides superior protection and longevity.
- Viscosity: 0W-20 is the standard grade for most 2017 Elantra models; 5W-20 may be acceptable if 0W-20 is unavailable, per the owner's manual guidance.
- Performance specification: API SN or SP service category; ILSAC GF-5 or newer.
- Oil capacity: About 4.2 quarts (4.0 liters) with a new filter.
- Maintenance interval: Change oil according to the vehicle’s maintenance minder; typically around 7,500 miles under normal driving with synthetic oil, more often in severe conditions.
In practice, follow the official grade and schedule, and always confirm the exact specification for your trim and region in the owner's manual.
Considerations by climate and engine variant
Engine variants and climate
The 2017 Elantra lineup is primarily powered by the 2.0-liter engine in most US-market models. Some international variants may offer different engines, such as smaller turbo or naturally aspirated options, but Hyundai’s modern practice typically requires 0W-20 synthetic for these engines as well. Always check the owner’s manual or contact a Hyundai service advisor for the exact specification for your VIN.
Conventional vs synthetic
Hyundai recommends synthetic motor oil for the 2017 Elantra to maximize protection and efficiency, particularly with direct-injection variants. If conventional oil is ever used, plan to switch to synthetic at the next oil change and verify the viscosity recommendation in the manual.
How to verify and maintain the oil yourself
These practical steps help ensure you’re using the right oil and keeping the engine properly lubricated.
- Consult the owner's manual or the under-hood label for the exact oil specification for your VIN, since regional variations can occur.
- Choose a reputable brand of synthetic 0W-20 (or 5W-20 if the manual specifies it as acceptable) meeting API SN/SP and ILSAC GF-5 or newer.
- Check the oil level after the engine has cooled, using the dipstick, and top up to the full mark if necessary with the correct oil type.
- Replace the oil filter with every oil change to ensure proper filtration and engine protection.
- Dispose of used oil responsibly at an authorized collection point or service facility.
Tip: Many Hyundai models use a maintenance minder that indicates when an oil change is due, so rely on the system in daily driving to guide service timing rather than a fixed interval alone.
Summary
The 2017 Hyundai Elantra generally requires a fully synthetic 0W-20 motor oil, with 5W-20 as a potential alternative if 0W-20 isn’t available per manual guidance. Use API SN/SP and ILSAC GF-5 or newer, and follow the maintenance minder for change intervals. Always verify exact specs for your trim and region in the owner's manual.
