Rock Oil’s R&D facility has successfully developed the next generation of 100% synthetic automotive racing oils – the Carbon Series. This development and extensive field trials with leading racing teams have resulted in a significant breakthrough in lubrication performance.

Market-leading additive technology has been combined with the three types of advanced next-generation synthetic base stocks. Independent tests have shown that conventional synthetic ester base oils of the highly polar type have an affinity for internal engine surfaces, which can be detrimental to 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 the Rock Oil Carbon Series products is demonstrated below:

Demonstration of performance:

The Sequence IV-A (ASTM D6891) is the oil industry’s benchmark flat tappet valve-train wear test.

API SL Limit = 120 microns maximum wear on cam lobes
API SM & SN Limit = 90 microns maximum wear on cam lobes
Rock Oil Carbon 5W-30 = 26 microns

In addition to outstanding wear protection, the Rock Oil Carbon Series has been developed to significantly reduce friction through unique friction modifier technology to release full engine power.

Product Code: 00970
  • Tri-Synthetic Formula – including Synthetic Ester, Polyalphaolefin (PAO) and a proprietary next-generation fully synthetic base oil
  • Outstanding resistance to Permanent Viscosity Loss (PVL) through the use of active, self-healing Viscosity Modifiers– extremely important for highly stressed, tight tolerance racing engines
  • Exceptionally low NOACK volatility – results in very low oil consumption
  • Unsurpassed wear protection – especially important for racing applications

CARBON SERIES products are available in four SAE viscosity grades – 5W-30, 0W-40, 10W-50 & 10W-60
