The heat transfer properties of automotive engine lubricants and basestocks were defined in terms of a calculated Figure of Merit values, determined by utilization of measured Thermal Conductivity, Specific Heat, Density, and Viscosity, revealed that lubricant basestock and the additive constituents have a significant effect on the resultant heat transfer characteristics of the lubricant. Formulated engine lubricants meeting MIL-L-2104C and MIL-L-46152 as well as two ASTM Reference Oils were evaluated. A multiviscosity product, Grade 10W-40, was found to exhibit the lowest heat transfer characteristics of all products examined indicating a need for additional work. Author
