Typical use
For engines specifying SAE 40 viscosity at operating temperature. Do not choose a thicker oil solely because a vehicle is older.
For vehicles with a DPF, check the required oil specification and OEM approval separately. Match the viscosity and standards to the vehicle and engine manufacturer requirements. Do not determine the oil-change interval from the product name alone.
