Rovas STOU 10W-30 is a high-performance multifunctional tractor oil (STOU) for all-year-round use in the agricultural and construction machinery. The product was developed for lubrication of the diesel and gasoline engines (with or without boosting), mechanical and hydraulic transmissions, gearbox/clutch systems with a shared casing, including brake systems with wet friction plates. Rovas STOU 10W-30 allows you to have only one oil type available at the storage for all the lubricated units. This oil also helps to avoid the risk of incorrect lubricant application. This product cannot be used in the diesel engines outfitted with a diesel particulate filter (DPF).
