TEXACO (SUTO) SUPER UNIVERSAL TRACTOR OIL EXTRA 10W-30 is a high performance multi-purpose 10W-30 multigrade Super Tractor Oil Universal (STOU) lubricant. It is specifically designed for use in tractor crankcases, transmissions, final drives and hydraulic systems. Super Universal Tractor Oil Extra is formulated with a mineral oil base and additive combination designed to help promote equipment performance and protection.
Applications: • Super Universal Tractor Oil Extra is specifically designed for use in engines, transmissions, rear axles and hydraulic systems of agricultural tractors and associated equipment where a “Super Tractor Oil Universal” (STOU) is required. It may also be used in applications calling for a “Universal Tractor Transmission Oil” (UTTO).
It is not recommended in heavy-duty powershift transmissions where a Caterpillar TO-4 fluid is specified.
• Super Universal Tractor Oil Extra fulfils many of the requirements of the GL-4 specification, in particular those relating to the low speed-high torque conditions that are typical in agricultural applications. However it does not fulfil all of the high speed-low torque requirements of the GL-4 specification, and so is not recommended for on-highway applications.
• Super Universal Tractor Oil Extra may also be used in mobile hydraulic systems and in mobile or stationary diesel engines. It is not suitable for use in all modern high-performance engines – please check the minimum requirements in the vehicle’s handbook.
