Blud Lubricants® now offers three distinct series of racing oils:

  • Blud Powersports Series: Our original line of premier advanced technology racing oils created for 4 stroke engines under most racing conditions. These are the best racing oils for the money on the planet!! Pros love Bludl! Note: The Blud Powersports Series is replacing MotoBlud, DirtBlud, BikerBlud and HawgBlud. Now all you need to know is the viscosity you want.

  • Blud Racing Pro Series: Formulated for racing at the top level. We designed this oil to protect and enhance the operation of high compression, highly tuned engines while maintaining a smooth transmission with excellent clutch control. Blud Racing Pro Series can increase horsepower and torque while reducing engine and clutch generated heat compared to a traditional petroleum racing oil. Use this product and your mechanic will thank you!

  • Blud Racing Pro Elite Series: A racing oil Beast!! Only for the most brutal of conditions - high heat, high humidity, silt, mud and/or all of these conditions. We believe that this is the finest racing oil on the market. There is nothing else like it available for the racing professional!!
