Mitsubishi CVT J-1

The Mitsubishi CVT J‑1 specification defines the requirements for transmission fluid intended for continuously variable transmissions (CVT) installed in passenger and commercial Mitsubishi models. The fluid must maintain stable viscosity over a wide temperature range, provide a low coefficient of friction for smooth movement of planetary rollers, and also exhibit high resistance to oxidation, wear, and foaming, ensuring long‑lasting operation under high load. CVT J‑1 is compatible with gasoline and diesel engines, including turbocharged units, and does not require special SAPS additives, making it safe for systems with catalytic converters and DPF. When selecting XENUM transmission oil that meets CVT J‑1, you receive a product that complies with Mitsubishi’s official requirements and provides optimal protection for gears, bearings, and seals. Modern variants such as CVT J‑1/ECO J‑4 remain backward compatible, so the same level of protection can be achieved in newer models.
