Royal Purple Synthetic Motor Oils

Frequently Asked Questions

Why Use Royal Purple?  See Attatched PDF Below.
 
Why is Royal Purple® superior to other motor oils?  Royal Purple® outperforms mineral and synthetic oils due to its superior synthetic base oils andits proprietary Synerlec® additive technology. Synerlec® significantly increases oil film strength to dramatically reduce friction and improve combustion. This translates into more horsepower and torque, improved fuel economy, and dramatically reduced wear and heat.  Royal Purple®Motor oils with Synerlec® have been proven to reduce exhaust emissions as well.
Are Royal Purple® lubricants compatible with other motor oils?  Yes. Royal Purple® lubricants are fully compatible with mineral or synthetic oils. No special procedures are necessary when switching to Royal Purple®.
Can I put Royal Purple® into my brand new car? Yes. Royal Purple® currently offers many viscosity grades of API Licensed Motor Oils. (See the Royal Purple® Motor Oil Product Page or visit the API Engine Oil Licensing and Certification Website for more information). To allow for proper break in of the engine, Royal Purple® recommends waiting until the manufacturer's first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal Purple® in diesel engines.
How often should I change Royal Purple® in my passenger car?  Royal Purple® recommends following the manufacturer's maintenance intervals while the vehicle is under factory warranty. In clean engines that are no longer under warranty, oil change intervals up to 12,000 miles with continued filter changes every 3,000 to 4,000 miles (top-off oil as needed) are recommended. In dirty engines, Royal Purple® recommends standard 3,000 to 5,000 mile oil and filter change intervals until the engine oiling system is clean and free of deposits, which are left by lower quality oils and / or poor maintenance or mechanical problems.  This will allow time to gradually remove existing deposits / contaminants without overloading the oiling system (pump, pick-up, filter, etc.). (Mechanical problems such as fuel dilution, coolant leaks into the crankcase, poor air filtration and / or failure to maintain proper oil level are all detrimental factors to the service life of any engine oil. Any one of these factors can significantly shorten the useful service life of any oil).
Will synthetic oil cause my engine to leak?  Properly formulated synthetic oils will generally not cause an engine oil leak. Synthetic oils possess a higher degree of natural solvency, which can clean and remove deposits left by other oils. The removal of extensive oil deposits can expose marginal or damaged oil seals that may then leak. If an engine currently has excessive oil consumption (i.e. greater than 1 quart / 1,000 miles) the recommended course of action is to solve the oil consumption problem before switching to a synthetic.
Should I use an oil additive with Royal Purple®?  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, corrosioninhibitors, 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.
Is Royal Purple® synthetic motor oil? Yes. Royal Purple® Motor oils are composed of a proprietary formulation of synthetic base oils and synthetic additives containing iso-paraffinic diluents.
