Abstract (en)
[origin: EP1967571A1] A liquid lubricant base oil composition comprising (i) a base stock comprising at least 95 % by weight saturated hydrocarbons such as for example a Group II base stock, a Group III base stock and/or a base stock derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon material and (ii) 0.2 to 30 % by weight of an aromatic extract may be made by blending the components together and may be used with one or more additives in a lubricant composition which may be used in applications such as marine engine lubricants.
