Hyundai/Kia JWS3314

JWS 3314 specification is an official transmission oil approval developed by the Hyundai Motor Company and Kia Motors groups to ensure optimal operation of their automatic gearboxes, including conventional hydraulic automatic transmissions, CVT, DCT, and hybrid transmissions. The technical requirements of JWS 3314 call for high heat resistance, viscosity stability across a wide temperature range, and effective gear wear protection, which allows proper cooling and minimizes the risk of overheating under high loads. This approved oil is suitable for gasoline and diesel Hyundai and Kia engines installed in models with automatic transmissions, including the popular i30, Tucson, Sportage, Sorento, K5 series and their hybrid variants. Although JWS 3314 does not impose restrictions on DPF systems, it is compatible with transmissions that operate in conjunction with catalysts and soot filters, providing safe operation without affecting exhaust cleaning. When you choose an XENUM transmission oil that meets JWS 3314, you receive a product that has completed the full OEM testing cycle and guarantees the preservation of warranty conditions and extended service life of your gearbox.
