FARMGUARD STOU
SAE 15W-40
Product Overview
STARKOL STOU 15W-40 is a versatile lub-ricant specifically engineered to simplify maintenance in modern agricultural ma-chinery by covering engine, transmission, hydraulic and wet brake or clutch lubrica-tion needs with a single product. Its stab-le formulation maintains strong oil film protection and smooth system operation in both high-load and extended service conditions.
Developed to withstand demanding field environments, it offers reliable protection against wear, oxidation and corrosion while supporting efficient power transfer across multiple sys-tems. This makes it a practical and cost-effective solution for tractors and other agricultural equipment used year-round.
• One oil solution for engines, transmissions, hydraulics and wet brakes
• Consistent performance under high thermal and mechanical stress
• Reliable wear, oxidation and corrosion protection
• Smooth operation for extended service intervals
• Simplified maintenance and improved operational efficiency
