The Arbor series lubricants produced by Petronas Lubricants International have been specifically designed to protect the latest-generation agricultural and industrial machinery—those equipped with low-emission engines and highly automated transmissions
European regulations aimed at reducing emissions from diesel engines have led designers to equip these power units with increasingly complex auxiliary systems. On the intake side, exhaust gas recirculation systems have been adopted to minimize the formation of nitrogen oxides during combustion, while the exhaust systems have been fitted with catalysts, filters, and urea-based treatments to block harmful gases and carbon particles.
The result has been engines much more complex and sophisticated than their predecessors, accompanied by parallel developments in fuels—which now contain far lower sulfur levels—and in lubricants, particularly those operating inside engines and transmissions.
An example of this evolution is the “Arbor” range developed by Petronas Lubricants International specifically to meet the functional needs of the latest diesel engines installed in agricultural and industrial machines subjected to intensive use. The engine oils are available in ten different formulations, eight of which are multigrade and developed from natural or synthetic bases (“AlfaTech Synt” and “AlfaPrime Synth”).
All ten ensure maximum mechanical protection thanks to specific additives that clean metal surfaces, protect moving parts from wear, counteract soot-induced thickening, and maintain these properties over time. Resistant to oxidation, they feature a viscosity that remains within nominal standards both during cold starts and when the engine is operating under load.
Complementing these are the transmission oils—multifunctional fluids capable of working efficiently inside a wide range of hydraulic systems, from transmissions to power circuits to oil-immersed brakes. Offered in nine different formulations, Petronas transmission oils—particularly the “Mtf” series—maximize hydraulic system performance thanks to high viscosity indices and strong thermal stability, qualities that ensure servo-control functionality and stable operating pressure across all temperatures.
Also noteworthy in the “Arbor” range is the “Brake D4” brake fluid, which has a high boiling point to prevent vapor lock—the formation of vapor bubbles that compromise brake system performance. It also has a low pour point, allowing it to operate effectively at low temperatures. Like all Petronas lubricants, it is available in Italy through a network of 1,945 service centers, 86 of which are dedicated specifically to the agricultural sector.
