Racing Lubricants

High performance motorsport places extreme stresses on a vehicle’s moving parts compared to everyday driving, making the correct choice of lubricants essential to maintaining performance, power and endurance. When it comes to Classic and Vintage motorsports, choosing the correct technology lubricant to match the period specification of mechanical components is critical. Providing excellent lubrication, oils need to be compatible with the type of seals and metals used throughout your vehicle. Other elements such as effective anti-foaming and heat transfer in systems that rely heavily on mechanical lubrication must also be effective and race proven.
