STOU 10W-30 is a Super Tractor Oil Universal (STOU) with a high year-round use performance in agricultural and construction equipment. It is intended for lubrication of diesel and gasoline engines, both turbocharged and non-turbocharged, mechanical and hydraulic transmissions, transmission/clutch systems with a common crankcase, including a brake system with wet-type friction discs. It cannot be used in engines with a particulate filter (DPF).
- High thermal and oxidation stability.
- Good detergent and dispersion properties.
- Very good low-temperature properties.
- Wear protection at a cold start.
- Ideal anti-foam, anti-wear, and anti-corrosion properties.
- Suitable for wet-type brake systems
According to international classifications, the oil meets:
The oil can be used in engines with the following requirements:
