Mitsubishi Dia-Queen SSTF-1

Mitsubishi Dia‑Queen SSTF‑1 specification is the official transmission oil standard developed by Mitsubishi Motors for automatic and continuously variable gearboxes, including traditional ATF, CVT and DCT. Oil that meets SSTF‑1 must have a high viscosity index, shear stability, excellent wear and oxidation protection, as well as precisely defined friction parameters that ensure smooth shifting and long bearing life. This standard is applied in gasoline and diesel engines of passenger and commercial Mitsubishi models, including turbocharged units, and guarantees compatibility with emission control systems such as DPF, without increased SAPS content. When selecting XENUM transmission oil marked as Dia‑Queen SSTF‑1, you receive a product that meets all OEM requirements and supports optimal performance and reliability of the transmission throughout its service life.
