Tractor engine and transmission oil formulated to deliver reliable hydraulic response and control engine soot and wear. Smith & Allan Tractor Oil gives farmers reassurance across long shifts and varied tasks. Is the level of protection suitable for regular agricultural use?
⚡ At a Glance
- • Lubrication Performance: Good hydraulic response, engine soot and wear control
- • Best for: Owners of tractors and farm machinery needing dependable engine and transmission protection
- • Not ideal for: Situations requiring manufacturer-specified OEM approvals that are not listed in the product details
Designed as a multi-purpose tractor oil with 15W-30 viscosity and STOU/SUTO designation. Focuses on hydraulic response, gear wear protection, and corrosion resistance.
Consistent hydraulic control – with low foaming tendency
Low foaming tendency reduces air entrainment in fluid circuits, helping hydraulic systems maintain steady pressure under load. Stable fluid behaviour supports predictable response from pumps and valves.
Maintained hydraulic responsiveness helps implements operate smoothly during repeated or heavy use, reducing hesitation during lifting and steering tasks.
Extended gear life – thanks to gear wear protection
Formulation aims to improve gear wear protection by forming a lubricating film between metal surfaces, lowering metal-to-metal contact during high-pressure cycles. Suitable for combined engine, gearbox and hydraulic service as indicated by STOU/SUTO designation.
Reduced gear wear translates into fewer maintenance interventions and longer component life for transmissions and final drives on farm machinery.
Corrosion defence in storage – with rust and corrosion protection
Rust and corrosion protection components help guard metal surfaces from oxidation and moisture-related damage during downtime and storage. Protection remains important where equipment sits idle for periods.
Corrosion resistance preserves internal parts during seasonal storage, helping avoid costly repairs when machines return to service.
