Isuzu Besco ATF II

Isuzu Besco ATF II is a specification developed by the Japanese manufacturer Isuzu Motors for automatic transmissions used in passenger, commercial and heavy‑duty models of the brand. The standard requires the transmission oil to have a certain viscosity range (typically V‑grade 6.0–7.5 cSt at 100 °C), high oxidation resistance, protection against gear wear and effective lubrication of hydraulic components. This oil ensures stable operation of automatic gearboxes in Isuzu D‑ and 4‑cylinder gasoline engines, including the N‑Series and F‑Series, as well as in heavy trucks and buses where the Besco system is used. It is compatible with conventional catalysts and does not contain high levels of sulfates, aromatics and phosphorus compounds (SAPS), allowing safe use in catalyst‑equipped systems, although special DPF additives are not provided. By using XENUM transmission oil designated as Isuzu Besco ATF II, you obtain guaranteed gearbox protection, reduced risk of overheating and compliance with the manufacturer’s warranty conditions.
