This test measures the antioxidants in petroleum products for the determination of remaining useful life.   The normal range is 0% - 100%. Samples are mixed with a solvent suitable to oil type, and then compared against stored reference oils. The percentage of the antioxidant additives are calculated and depending on their level a calculation of remaining useful life (RULER) is measured.
