Optima D2 Diesel Engine Oil provides premium quality service in both diesel and gasoline engines. It is specially
formulated for heavy-duty service in diesel engines found in both on-highway and off-highway vehicles and
equipments.
Optima D2 Diesel Engine Oil is specially formulated with advanced dispersant technology to resist oil thickening caused by
incomplete engine combustion, which generates soot. The dispersant minimizes sludge formation and effectively keeps particles
in suspension to extend filter life.
Optima D2 Diesel Engine Oil is recommended for use in over the road diesel trucks, heavy-duty construction equipment, oil field
engines, farm vehicles and passenger diesel cars, as well as for mixed fleet operators to use a single line of motor oils for all
vehicles.
