PETRONAS Arbor Super 20W-50 is a mineral engine oil dedicated to agricultural and construction machinery. It keeps machines efficient and extends their service life by protecting against oxidation, decomposition and wear, while maintaining optimal piston cleanliness and viscosity stability - a solution for high, long-lasting performance in hard daily work that protects tireless machinery from loss of performance and unplanned downtime. The oil is suitable for all types of heavy-duty diesel applications, including turbocharged and naturally aspirated diesel engines of tractors, farm machines and earthmoving equipment, running on high- or ultra-low-sulphur diesel. It maintains the oil at optimal viscosity levels to prevent unplanned breakdowns, reduces the acidic levels that lead to corrosion for a longer, more durable engine life, and effectively combats high concentrations of soot build-up, critical to preventing loss of engine horsepower. PETRONAS Arbor Super 20W-50 meets and exceeds API CF-4/SG and the MIL-L-2104 F and NH 336 G performance levels. Typical data: viscosity 19 mm²/s at 100°C, viscosity index 130, TBN 6.4 mgKOH/g, flash point above 220°C, pour point -27°C.
