NOTE: For best performance and maximum protection of all types of operation, select only those lubricants which:

Satisfy the requirement of the ACEA, API or ILSAC classification.
Have proper SAE grade number for expected ambient temperature range.
Lubricants that do not have both an SAE grade number and ACEA, API or ILSAC service classification on the container should not be used.
