Patent ID: 8759266

Claim:
An industrial oil composition comprising: a base oil consisting essentially of a GTL oil; and a non-metallic antistatic additive to provide said lubricant composition with an electrical conductivity of at least about 50 pS/m at 25° C. and a dielectric strength of at least 300V/ml whereby said industrial oil composition has improved electrical properties as evidenced by said dielecric strength when compared to industrial oil compositions comprising a Group II or Group III base oil containing the same antistatic additive in the same amount of the claimed composition, wherein said base oil is about 99 wt % of the lubricant composition, wherein the non-metallic antistatic additive is dinonyl naphthyl sulfonic acid, and wherein said non-metallic antistatic additive is present in amount of about 6 μl/L and with the proviso that the composition is essentially free of dispersants.
