Farm Oil 15W/40 is a specially crafted Super Tractor Oil Universal (STOU), designed to cater to tractors’ lubrication needs with a single, versatile solution, eliminating the need for up to four or more different oils.


This remarkable Farm Oil variant possesses the full spectrum of lubrication properties required to ensure extended trouble-free operational lifespans for a wide array of agricultural power-driven equipment. It comes highly recommended for various engines, encompassing modern four-stroke diesel engines (both normally aspirated and turbocharged), gasoline engines, as well as transmissions, differentials, final drives, hydraulic systems, wet brakes, and power take-off clutches.


What makes Farm Oil 15W/40 truly exceptional is its versatility; its benefits extend beyond the farmstead. It enhances the performance of power-driven equipment used in demanding off-highway applications such as construction, transport, mining, industrial settings, and marine environments. Additionally, it offers the added advantage of reduced lubricant inventories, making it a cost-effective choice for a wide range of applications.



ONE FLUID REDUCES INVENTORY. Farm Oil 15W/40 can replace four or more tractor lubricants. It is recommended for engines (diesel and gasoline), wet brake transmissions, differentials, final drives, hydraulics and power take-off clutches. Farm Oil 15W/40 simplifies tractor services and overcomes the possibility of misapplication of incorrect lubricant which otherwise may result in damage to the engine components.

DIESEL DETERGENCY & DISPERSANCY. High temperature detergents and dispersants in Farm Oil 15W/40 minimise the formation of top land ring and valve deposits and sludge development in both high and low load conditions. These additives guard against ring sticking and are further enhanced by oxidation, rust and corrosion inhibitors.

BORE POLISH DEFEATED. Top land and ring carbonaceous deposits are effectively minimised by Farm Oil 15W/40 so that the polishing action of the carbonised materials is avoided. If left uncontrolled, the deposits result in bore polish which leads to progressively higher oil consumption and shorter engine life.

ANTI-WEAR & EP ACTIVITY. These special characteristics of Farm Oil 15W/40 ensure effective lubrication when high load conditions are experienced in transmissions, axles, engines and hydraulic systems. They cumulatively promote long service life and trouble-free operation to tractors.

POWER TAKE-OFF LIFE.   Great life extension because Farm Oil 15W/40 has the special ability to quickly stall to prevent the clutches from slipping and burning out when a tractor driven implement hits any large object in the field. Farm Oil 15W/40 provides faster stall times which reduce clutch wear and prolong PTO life.

BRAKE CHATTER. Means greater braking difficulty and ultimately premature failure. Farm Oil15W/40 suppresses chatter without loss of braking capacity. The balanced friction control ensures proper functioning of the wet brake and PTO clutches.

SEAL SWELL. Properties of Farm Oil 15W/40 are especially balanced so that seal gasket and wet brake compositions do not deteriorate, thereby avoiding costly repairs and down time.

FILTERABILITY. Superior to competitive fluids. Farm Oil 15W/40 overcomes the tendency of filter plugging, which can occur with other fluids when operating in moisture contaminated service conditions, and thus lubricant supply is assured to all the appropriate moving surfaces.


Farm Oil 15W/40 meets most tractor OEM specifications, as well as many hydraulic pump and hydraulic transmission specifications.
