Royal Purple Synthetic OEM Motor Oil

Royal Purple Motor Oil is recommended for use in all four-cycle gasoline engines and both two-cycle and four-cycle diesel applications including cars, trucks, motor homes / RVs, boats, commercial fleet and stationary industrial diesel engines.

Royal Purple Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec additive technology.

Synerlec additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup.

Environmentally Responsible: Royal Purple Motor Oil extends oil drain intervals. Less oil is purchased and less oil is being disposed of—It's good for your vehicle, and good for the environment!

Royal Purple outperforms synthetic and conventional oils due primarily to its proprietary Synerlec® technology, and due to its superior synthetic base oils. Synerlec significantly increases oil film strength to dramatically reduce friction and improve combustion. This translates into more horsepower and torque, improved fuel economy, and reduced wear, heat and emissions.

What kind of performance gains can be expected?

Multiple independent university and automotive industry testing has documented these typical performance gains:

  • Horsepower and torque increases up to 3%.
  • Fuel economy improvement up to 5% or more.
  • Reductions in emissions of 20% or more.
  • Reductions in heat of up to 12%.
  • Reductions in wear of up to 80%.

Performance gains will vary depending on the type of vehicle, its condition, and the way it’s driven. Visit the independent test summary page to view specific test results.

Royal Purple's motor oils are formulated to provide unparalleled performance and protection and comply with API / ILSAC specifications. Its racing oils vary in viscosity and formulation as compared to the SAE motor oils to provide the greatest performance gains possible without regard to API, SAE and / or ILSAC specifications.
