Selection Of Engine Oil: Notes

NOTE: For best performance and for maximum protection for all types of operation, select only those lubricants which:
  • Confirm the requirements of the API classification.
  • Have proper SAE grade number for expected ambient temperature range. Lubricants which do not have both a SAE grade number and an API service classification on the container should not be used.
