About this item.....
Rock Oil Synthesis 4 Racing 15/50 has lubricated the engines for many British championship winners both during and after development.
Rock Oil S4R 1550 fully synthetic 4 stroke oil has been designed to protect the motorcycle engine under extreme racing conditions.
Synth 4 Race 15 50 is the only choice if you want to get the very best from your motorbike engine and its ultra low volatility and high shear stability reduces consumption and helps S4R stays in grade longer whilst the phenomenal film strength and shear stability protect the engine components, including clutch and gearbox parts, from wear.
Synthesis 4 Racing is developed from the most advanced synthetic base stocks (PAO and Ester) coupled with the latest additive technology to give outstanding performance.
Synth 4 Race full synthetic is suitable for all modern high performance 4 stroke engines that require a 15w50 oil and can be used for road going or racing motorcycle engines. FREE DELIVERY
