Heavy-duty specifications are evolving as engines, aftertreatment systems and greenhouse-gas targets continue to raise the bar for lubricant performance. Fleets, OEMs and oil marketers now need engine oils that can balance oxidation control, soot handling, wear protection, aftertreatment compatibility and fuel-economy performance across a more complex mix of API, ACEA and OEM requirements.

From this page, you can explore API, ACEA and OEM specification pages, explore supporting tools and technical videos and access education and key insights that helps translate specification change into formulation decisions. If your application shifts into construction, mining or agricultural equipment, this page should also help you locate the related heavy-duty off highway specification details.
