Oil, Lube, and Fluids

Why is Royal Purple superior to other motor oils?
Royal Purple Motor Oil is a blend of synthetic oils that aims to improve engine performance and protection, reduce emissions and increase fuel economy. Because it adheres to engine surfaces after shutdown, it provides protection during startup. Royal Purple claims its product also increases horsepower and torque while reducing wear and heat within the engine.

Royal Purple outperforms synthetic and conventional oils primarily due to its proprietary Synerlec technology and 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:

  • Fuel economy improvements of up to 5% or more.
  • Horsepower and torque increases of up to 3%.
  • 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.

    Max ATF® Transmission Fluid


    Max ATF® is a synthetic, high performance, long life, multipurpose, transmission fluid and is recommended for all transmissions requiring Ford Mercon® or GM Dexron® III transmission fluids. This includes the automatic as well as the manual transmissions in late model Mustangs.

    Max ATF® significantly reduces heat to extend the life of your transmission. Automatic transmissions generate a great deal of heat and depend upon the transmission fluid for cooling and protection. More than 90 percent of all automatic transmission failures are caused by overheating; a 20°F reduction in fluid temperature can double the life of the transmission (Source: Perma Industries, Inc.).

    Max ATF® is fully compatible and can be mixed with other automatic transmission fluids; however, for the best results drain or flush the current oil and then fill with Max ATF.

      Max ATF® Transmission Fluid Advantages:

    • Greater Wear Protection
    • Increases Fluid Life
    • Promotes Clean, Efficient Equipment
    • Extends Equipment Life
    • Increases Oil Life
