PETRONAS Arbor Universal 15W-40 is a premium-quality universal lubricant (S.T.O.U.) dedicated to agricultural and construction machinery, keeping it efficient and offering a longer service life - the right solution for high, long-lasting performance in hard daily work, protecting tireless machinery from loss of performance and unplanned downtime. Designed for the engines, transmissions, hydraulic systems and wet brakes of farm tractors and machinery, it improves business profitability and vehicle availability while significantly reducing operating costs. It provides high anti-wear protection for the mechanical components of the engine and transmission and an excellent ability to keep engine, transmission and hydraulic systems free of deposits and sludge. Balanced friction modifiers deliver high braking efficiency in wet brakes; the viscometric stability across temperature changes keeps system pressure high and constant for prompt response of the hydraulic servo controls; and good low-temperature viscosity improves lubrication at start-up. PETRONAS Arbor Universal 15W-40 meets API CF-4/SF and API GL-4, holds ZF TE-ML 06B and 07B approvals, and meets the CAT TO-2, NH 030 C and SDFG OU-1391 performance levels. Typical data: viscosity 14 mm²/s at 100°C, viscosity index 135, TBN 11 mgKOH/g, CCS 4500 mPa·s at -20°C, pour point -36°C.
