摘要：
Provided are lubricant compositions comprising a hydrocarbon base oil and a polyoxybutylene polymer prepared by polymerizing butylene oxide with a monol initiator and having a number average molecular weight ranging from 800 g/mol to 1200 g/mol. The polyoxybutylene polymer functions as a highly active friction-modifier additive.
