High Performance Race and Road Engine Lubricants

The Carbon Series marks a major breakthrough for not only the R&D team at Rock Oil but for the lubricant industry as a whole. Utilising the very latest chemical technology it promises to deliver performance and protection for high performance race and road engines. Rock Oil has long supported motorsport in the motorcycle market and lubricated the engines of multiple world champions. This expertise and desire to offer only the best possible products has resulted in the development of the Carbon series.

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 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 the Carbon Series products demonstrated below:

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, to release full engine power the Rock Oil Carbon Series has been developed to significantly reduce friction through the use of unique organic friction modifier technology.

The Carbon Series was subject to a vigorous and intense succession of development through both field-trials with motorsport partners and extensive laboratory testing. Our vast experience in motorcycle racing ensures all products manufactured in our factory meet the exacting standards required at this level. The range consists of four viscosities 5W-30, 0W-40, 10W-50 & 10W-60, which between them cover all major engine applications in the high performance automotive market. The range can be used in both motorsport and fast road applications and offers users the reassurance that their engine is both protected and releasing maximum power.
