Rock Oil’s R&D facility has successfully developed the next generation in 100% synthetic racing oils – Synthesis XRP Off-Road. This development, in conjunction with extensive field-trials with leading off-road racing teams has resulted in a significant breakthrough in performance.

Market-leading additive technology has been combined with the three types of advanced next-generation synthetic base stocks. Tests have shown that conventional synthetic ester base oils of the polar type have an affinity for internal engine surfaces, which can actually be detrimental for wear protection. (These esters can compete with additives for the surface, reducing additive performance). Our latest non-polar extreme performance esters do not compete with anti-wear additives for the surface; hence the step-change in wear protection realised by Synthesis XRP Off-Road products is demonstrated below:

Sequence IV-A (ASTM D6891) is the oil industry’s benchmark valve-train wear test.
API SL Allowable = 120 microns maximum wear on cam lobes
API SM & SN Allowable = 90 microns maximum wear on cam lobes

To release full engine power the Synthesis XRP Off-Road Range has been developed to significantly reduce friction without the use of Friction Modifiers. (Commonly known as Molybdenum Disulphide, Graphite, Teflon® and all Nanotechnology lubricant additives) This is extremely important when the lubricant is used in engines with a wet (oil-immersed) clutch.
