Hyundai/Kia

HYUNDAI/KIA approval is the official program of the Hyundai Motor Company and Kia Motors groups, which defines the requirements for transmission oils and fluids for their automatic gearboxes, CVT, DCT and hybrid transmissions. Technically this means that the product must provide stable hydraulic action, effective cooling, protection against wear of gear wheels and friction elements, and also maintain viscosity over a wide temperature range and under high loads. Specifications such as ATF 040000C90SG, JWS 3314, SP‑II‑IV are targeted at gasoline and diesel engines of Hyundai and Kia, including models with DPF systems where compatibility with the catalyst is important. Using oil that meets this approval helps maintain warranty conditions and extend transmission life, ensuring smooth operation even under extreme operating conditions.
