F+L Week 2019 | Dr. Ken Han | A new low viscosity base oil for fuel economy engine oil
A continued move to lower viscosity lubricants is becoming a trend in the development of modern automotive lubricants. Lower viscosity lubricants are known to contribute to improved fuel economy benefits. However, it is well known that lower viscosity base oils of the same chemical family are normally more volatile with lower viscosity index. Low viscosity base oils which have both a high viscosity index and a low NOACK volatility are highly desired but also a great technical challenge. A new series of oil soluble polyalkylene glycols were designed and developed to combat this challenge. These new base oils exhibited performance benefits of high VI, good low temperature viscosity and Noack volatilities compared to benchmarks.
