Will synthetic oil cause my engine to leak or consume more oil?August 17, 2018
Does Royal Purple maintain its purple color after it’s put into service?August 17, 2018
No. We strongly recommend against using any oil additives as do most automotive manufacturers. Engine oils are formulated with a fine balance of additives (anti-foam, corrosion inhibitors, anti-wear, detergent / dispersants, oxidation inhibitors), and more is not necessarily better. The use of an oil additive could upset the balance resulting in reduced performance.
