Built for the Jobs That Can’t Stop

Farm days don’t wait on oil changes. That’s why Gulf Western Super Tractor Oil Universal is blended to handle long hours, heavy implements & changing temperatures without thinning or breakdown. It keeps hydraulic lift performance smooth, reduces clutch chatter & ensures reliable lubrication from start to shut-down.

Across Somerville & the Mornington Peninsula, workshops servicing agricultural, earthmoving & contracting equipment rely on STOU to minimise machine downtime & simplify maintenance. One drum covers multiple systems, cutting costs & storage space without compromising protection.

The balanced additive system in Farmoil 15W-40 resists oxidation & foaming, keeping oil pressure steady during extended work periods. In hot Australian conditions, it maintains viscosity to prevent wear, while in cooler regions it flows freely for easy cold starts.

For total farm maintenance, link your oil program with Air Tools & Compressors for power during service work & Tool & Equipment Care for protecting tools & gear after the job. Add Tyre Repair & Changing Tools for field maintenance & use Measuring & Layout Tools for inspection checks on hydraulic pressure & fluid levels.

Industrial Shed backs every order with Warranty & Parts Support & fast nationwide delivery, keeping your workshop stocked & ready to handle any season or workload.

► Universal oil for engines, hydraulics, transmissions & wet brakes
► Formulated for Australian farms & mixed-use machinery
