Royal Purple break-in oil is designed for the engine builder who has grown increasingly concerned that current engine oils that are API licensed for new cars and trucks do not provide adequate wear protection for their freshly built performance engine, particularly those using flat tappet camshafts and lifters. Royal Purple break-in oil is formulated to provide the critical wear protection needed by the engine valve train and camshaft while allowing new piston rings to quickly seat to the engine cylinder walls. Royal Purple break-in oil combines highly refined mineral oil (preferred for engine break-in) with an advanced additive package containing elevated levels of zinc/phosphorus anti-wear additive to optimize wear protection during the sensitive engine break-in phase. Royal Purple Break-In Oil is a fully formulated conventional 10W-30 engine oil and does not require the use of any other chemical additives. Royal Purple recommends using Royal Purple break-in oil for a minimum of 500 to 1,000 miles in street driven gasoline engines to assure that the complete ring break-in has been completed before switching to one of their full synthetic engine oils. If need be, you can use for up to 2,500 miles.

Royal Purple Premium High Performance motor oil combines premium synthetic base oils with proprietary additive technologies to exceed protection and performance requirements of new modern engines. These often include smaller displacements, turbo chargers, gasoline direct injection (GDI), and start/stop systems. Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.

Royal Purple Purple Ice is a high performance synthetic radiator coolant additive for both gasoline and diesel engines. It is formulated to reduce the surface tension of the coolant, which improves heat transfer through the cooling system, while providing additional protection against rust, corrosion, and erosion. Royal Purple Purple Ice Radiator Super Coolant Additive prevents the formation of scale deposits in the radiator for optimum coolant flow and lubricates the seals of the water pump. One bottle will treat 3 to 5 gallons. It is ideal for use in straight water racing applications or in antifreeze/water mixtures. Purple Ice is compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool antifreeze coolants.
