Abstract
A composition is provided that contains a major amount of a base oil and a minor amount of at least one butylene oxide-modified alkyl-bis-ethoxylated monoamine, wherein the alkyl group have carbon atoms in the range of 8 to 22 and ethylene oxide to butylenes oxide is in a ratio in the range of about 3:1 to about 2:1. The composition provides improved friction modification in fuel and in lubricating oils.

A composition comprising:
- (a) a major amount of a base oil and (b) a minor amount of at least one butylene oxide-modified alkyl-bis-ethoxylated monoamine, wherein the alkyl group have carbon atoms in the range of 8 to 22 and ethylene oxide to butylenes oxide is in a ratio in the range of about 3:1 to about 2:1 and nitrogen to ethylene oxide ratio in the range of 1:2 to 1:3.
A lubricating oil composition comprising (a) a major amount of mineral and/or synthetic base oil and (b) a minor amount of at least one butylene oxide-modified alkyl-bis-ethoxylated monoamine, wherein the alkyl group have carbon atoms in the range of 8 to 22 and ethylene oxide to butylenes oxide is in a ratio in the range of about 3:1 to about 2:1 and nitrogen to ethylene oxide ratio in the range of 1:2 to 1:3.
