The following are the approved API and ACEA lube oils for your engine: 
Approved API Oils: 
Minimum: CF-4 
Approved ACEA Oils:

4.1.2. Viscosity 
Oil changes that are governed by the seasons can be avoided by using multi-grade lube 
oils. Multi-grade oils, particularly light-flowing oils, help reduce fuel consumption. 
This engine is equipped with an oil pan heater. Since it is designed and intended to 
operate continuously the engine oil will always be warm. Therefore, 15W40 viscosity oil 
can be used year round. Otherwise please use the chart below to determine the proper 
viscosity of oil that is to be used in your engine.
