The automatic transmission fluid is Hyundai ATF SP-III, and the manual transmission uses GL-4 gear oil. Always verify the exact specification for your vehicle in the owner’s manual or with a Hyundai dealer, as regional variations can apply.
In 2012, the Elantra offered both automatic and manual transmissions depending on the trim, so fluid requirements depend on which gearbox your car has. The following sections detail the standard specifications and how to confirm the correct fluid for your model.
Automatic transmission fluid (Elantra 2012)
Options you may encounter when selecting ATF for the 2012 Elantra automatic transmission.
- Hyundai ATF SP-III
- Dexron II/III-compatible ATF (use only if SP-III is unavailable and your manual allows compatibility)
Using SP-III is the preferred option for most 2012 Elantras with automatic transmissions; Dexron II/III compatibility can be acceptable in some regions or service scenarios, but SP-III is the manufacturer-recommended fluid in most markets.
Manual transmission fluid (Elantra 2012)
Options for manual gearboxes in the 2012 Elantra.
- MTF meeting GL-4 specification (Hyundai-brand MTF or equivalent GL-4-rated product)
- GL-4 75W-85 or 75W-90 gear oil (viscosity as specified by the manual; some markets may list a slightly different grade)
Use a GL-4-rated manual transmission fluid; the viscosity should match the manual’s specification (commonly around 75W-85 or 75W-90). If you’re unsure, consult the owner’s manual or a Hyundai service center.
How to confirm the correct fluid for your car
Check the owner’s manual, the transmission dipstick label (if present), or contact a Hyundai dealership to confirm the exact fluid specification for your VIN, especially if your car falls into a regional production window with variant guidelines.
Summary
For a 2012 Hyundai Elantra, the recommended fluids are Hyundai ATF SP-III for the automatic transmission and GL-4 gear oil for the manual transmission (with the exact viscosity specified in the owner's manual). When in doubt, verify the specification for your exact vehicle with the manual or a Hyundai dealer.
