Asperities were filled with ferrous ions when the moving piston rubbed the cylinder walls in the SRS test carried out. The heat activated in the ferrous ions that filled the asperities formed an undiluted complex chemical liquid which released energy that served as sacrificial material for metal which would have been removed in wear, a process known as energy release (ER). The energy release (ER) was investigated using falling weights which produced shock response (SR). The source of ER in the experiment was a combination of potential energy of the falling weights and the energy transfer due to the movement of the piston in the lute oil container. The shock response spectra (SRS) showed SAE 40 to have a high ER build up but very slow dissipation rate. SAE 40 is thus ideal as a lubricant for high speed engines, because ferrous ions were available to cover asperities and thus wear was controlled. The SRS showed Marfak 3 to have a low ER build up and rapid dissipation rate. Ferrous ions were unavailable to cover asperities and friction did set in, with high speed engine usage of Marfak 3. Therefore Marfak 3 is only suitable for greasing with slow speed engines. Dot 3 produced SRS with intermittent build up and dissipation of ER when compared to SAE 40 and Marfak 3, a quality which was ideal for usage as brake fluid.
