RUBIA FLEET HD 200 40 is recommended for all turbocharged or naturally-aspirated diesel engines of commercial vehicles (trucks, buses, vans, pick-ups, taxis…), and for all off-road applications (public works, agriculture, navigation, rail road) requiring API CF performance. This lubricant is also suitable for all diesel stationary engines (energy production). RUBIA FLEET HD 200 40 is well suited for gear boxes, torque converters and hydraulic systems when the manufacturer requires engine oil with an appropriate grade for these applications.
