Zusammenfassung:	A lubricant composition is disclosed. The lubricant composition is made up of (a) an API Group III base stock; (b) one or more semi-crystalline viscosity modifier; and (c) one or more LOFIs having a side-chain distribution which satisfies t he following requirements: (1) the distribution contains side chains ranging fr om C8 to C18 with an average carbon number ranging from 12.4 to 14.4; (2) the side chain distribution is bi-modal with a lower portion of the bi-modal distribution made up primarily of C12 and an upper portion of the distribution made up primarily of C16, C18 or combinations thereof; (3) the total mole % of the upper portion of the distribution must be less than that of the lower portion of the distribution; and (4) the amount of C12 on the side chain must be at least 40 mole % of the total side chain distribution.
