TRIAX Agra Supreme 15W-40 CK-4 is a full synthetic engine oil, suitable for heavy-duty conditions, designed to exceed almost all standards set for specifications and performance levels in its category. It is specially designed for agricultural and heavy off-road machinery applications, where engines operate 95% of the time at 95% of maximum power.

TRIAX Agra Supreme 15W-40 CK-4 is made from 100% synthetic, ultra-clean base oils, enhanced with modern additives such as organic lead, boron, and ZDDP with a high phosphorus concentration, incorporated into CRP technology. This combined formula provides unique engine protection, making it highly resistant to oxidation, nitration, and thermal breakdown, while reducing friction.

• Allows extended oil change intervals, longer than conventional diesel engine oils.
• Recommended for engines equipped with diesel particulate filters (DPF), exhaust gas recirculation (EGR) systems, and selective catalytic reduction (SCR).
• Wear protection and absolute viscosity control.
• Excellent fluidity down to -36 degrees Celsius for quick lubrication action and immediate winter starting.
• High TBN 10.5 for maximum protection against acidity and corrosion.
• Exceptional viscosity stability and oxidation resistance.
• Ensures oil film integrity to prevent metal-to-metal contact in critical engine parts.
