Can mil-l-23699 turbine engine oil be used in motor vehicles?

MIL-L-23699 turbine engine oil is specifically formulated for aviation turbine engines and is not designed for use in motor vehicles. While it may provide some lubrication properties, it lacks the necessary additives and viscosity required for automotive engines, which could lead to inadequate performance and potential engine damage. It's best to use oils that meet the specific requirements set by the vehicle manufacturer.
