BSE 2484 Lab 11 (Lubrication & Cooling Systems) STATION # 1 (Motor Oil) Society of Automotive Engineers (SAE) Viscosity (weight) The ability for an oil to flow at a given temperature The lower the SAE number the greater the flow at a given temperature Engine oil is generally between: SAE 0 (Very thin oil that will flow at very low temperature) SAE 50 (Heavy oil that maintains a good oil film even at very high temperatures) American Petroleum Institute (API) Service Grade (application) API designations starting with the letter: S = Spark ignition engines O = Moderate duty compression ignition engines C = Severe duty compression ignition engines API designations also end in a letter the later the letter comes in the alphabet the newer the service specification You can always use a later specification, but never an earlier one The Society of Automotive Engineers (SAE) ____________ is a measure of the fluidity (ability to flow) of an oil at a given temperature.
