Product Description ------------------- Royal Purple’s API-licensed Motor Oil combines premium base oils with proprietary additive technologies to create high performance synthetic oil that optimizes engine performance. Royal Purple API-licensed engine oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1* oline engine oil approval. .com ---- Royal Purple’s API-licensed Synthetic Motor Oil combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance. Royal Purple’s API-licensed motor oil delivers superior protection and improves performance in oline and diesel engines. Royal Purple’s API-licensed SN motor oil meets ILSAC GF-5 and Dexos1 performance requirements. No special procedures are necessary when upgrading to Royal Purple. Royal Purple recommends waiting until the manufacturer’s first scheduled oil change in new oline and diesel engines before upgrading to Royal Purple. Royal Purple motor oil is compatible with synthetic and conventional motor oils. Performance Advantages ---------------------- * Better wear protection--Enhanced additive technology prevents metal-to-metal contact beyond both Dexos1 and ILSAC GF-5 specs. * Increased fuel efficiency--A low coefficient of friction results in optimized fuel efficiency (the fuel economy of Royal Purple's 5W-30 meets the fuel economy requirements of a 5W-20 oil). * Better protection of the expensive catalytic emission system--Patented ZDDP additives optimize emissions catalyst system life. * Improved compatibility with fuels containing ethanol--Patented additive technology prevents the white sludge and lubrication starvation that can occur with 20% or higher ethanol fuel. * Superior corrosion protection--No rust observed in standard industry testing. Available in Multi-Grade and Monograde Oil Viscosities ------------------------------------------------------ Royal Purple API-licensed motor oil is available in both multi-grade and monograde oil viscosities, each of which meets API-licensed warranty requirements for oline engines: Multi-grade Oils* 0W-20 * 0W-40 * 5W-20 * 5W-30 * 5W-40 * 10W-30 * 10W-40 * 15W-40 * 20W-50 Monograde Oils* SAE 30 * SAE 40 * SAE 50 Fully Compatible with Other Motor Oils -------------------------------------- Royal Purple lubricants are fully compatible with mineral or synthetic oils. No special procedures are necessary when sw to Royal Purple. Royal Purple and New Vehicles ----------------------------- Royal Purple currently offers many viscosity grades of API-licensed motor oils. 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 oline engines. Allow 8,000 to 10,000 miles before using Royal Purple in diesel engines. Can Royal Purple Motor Oil Be Used In Older Engines? ---------------------------------------------------- Yes. Mileage and/or age is not a factor when used in a mechanically sound engine. In high-mileage applications, it's recommended running a minimum of two short (3,000 mile/5,000Km) intervals before extending the oil drain intervals. This will enable Royal Purple’s high solvency to remove existing deposits gradually; such deposits can restrict oil flow, if excessive, as well as reduce the oil service life significantly. Will Sw to 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 previous oils. The removal of extensive oil deposits can expose marginal or damaged oil seals, which 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 sw to a synthetic.
