Antioxidants are used to protect lubricating oils from the deleterious effect of oxidation. These include increase of acid number, the formation of deposits, and possibly viscosity increase. Considering that the varnish potential of an oil is measured by the MPC protocol it is relevant to establish correlations if any between RULER trends and MPC trends for a variety of commercially available formulations under laboratory conditions.
