Synthetic Diesel Engine Oil specially designed to meet new Proposed Category 11 (PC-11) specifications for heavy-duty-vehicle. A new category is split into two separate and distinct subcategories: one that preserves historical heavy-duty oil criteria and one that provides additional fuel efficiency and economy benefits for modern diesel engine technology while maintaining durability. This oil improves engine performance criteria that are being addressed including oxidation stability, shear stability and aeration.

It is specially formulated with synthetic blend technology to ensure optimal performance under severe operating conditions, reducing fleet management downtime and maintenance.
