JASO CVT 8 Hybrid

JASO CVT 8 Hybrid is a specification developed by the Japanese Association of Motor Oil Standards (JASO) for continuously variable transmissions (CVT) used in hybrid electric drivetrains. The requirements include stable viscosity over a wide temperature range, high resistance to oxidation and thermal degradation, as well as optimized friction characteristics that provide smooth torque transfer and minimal energy loss. The specification is targeted at hybrid engines with CVT, in particular systems installed in the Toyota Prius, Honda Insight, Lexus CT 200h and similar models, as well as conventional CVTs in passenger cars where bearing durability and protection of polymer and metal components are important. Oil that meets JASO CVT 8 Hybrid is compatible with catalysts and after‑treatment systems because it contains no harmful SAPS, allowing safe operation in vehicles equipped with DPF and three‑way catalytic converters. In our catalogue this requirement is represented by the transmission oil XENUM XA‑TRAN CVT 1 л, which provides reliable protection for the CVT gearbox and maintains the claimed efficiency of the hybrid transmission.
