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.
Diesel engine oil, API CF-4 performance level
API's service category for high-speed four-stroke diesel engines, of the generation preceding the emissions standards. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
Petrol engine oil, API SG performance level
API's service category for spark-ignition engines, of the late 1980s. An earlier category in the API service classification, written for the engines of its era; it still appears on datasheets alongside the current categories.Source
MIL-L-2104F — military engine oil
The last issue of the US military combat-vehicle engine oil specification before it was withdrawn in favour of commercial API/ILSAC categories.
