For a 1997 BMW 740iL, it is recommended to use synthetic oil with a viscosity of 5W-30 or 10W-30, depending on the climate and driving conditions. Look for oils that meet the BMW Longlife specifications, such as BMW LL-01 or LL-04. Always check the owner’s manual for specific recommendations and ensure that the oil meets the necessary performance standards.
