Patent ID: 7687445

Claim:
A lubricating oil, comprising: a. at least 5 wt % of a lubricating base oil, made from a waxy feed, having: i. greater than 10 wt % molecules with cycloparaffinic functionality, ii. a ratio of molecules with monocycloparaffinic functionality to molecules with multicycloparaffinic functionality greater than 20, and iii. a viscosity index greater than an amount calculated by the equation: VI=28×Ln(Kinematic Viscosity at 100° C.)+95; and b. a lower ash DI additive package; wherein the lubricating oil contains less than 0.2 wt % viscosity index improver which is a homo- or co-polymer or derivative thereof of number average molecular weight of about 15000 to 1 million atomic mass units; and wherein the lubricating oil has a sulfated ash by ASTM D 874-00 of 1.0 weight percent or less, and a cold cranking simulator viscosity at −20° C. less than 9000 cP.
