OEMs must improve fuel economy to meet tightening CO2


emissions legislation.


Lubricants enable CO2


reduction


Ultra low viscosity can help to meet the latest emissions legislation, but what are the implications?


Jonathan Flemming, Infineum Senior Lubricant Development Technologist, explores the drivers for low viscosity lubricants and reveals how reliable data and extensive market knowledge help Infineum to forecast the impacts that future viscosity trends could have on lubricant formulations.


Ultra low viscosity SAE 0W-16 oils can now be licensed as API SN, and some OEMs are already talking about SAE 0W-8, or even 0W-4. As viscosity gets lower and lower, the lubricants industry needs to understand the implications this trend will


have on a wide range of factors including base stock selection, viscosity modifier demand, hardware performance and future formulation complexity.


Driving factors It is well understood that CO2 emissions make a significant


contribution to the greenhouse effect, and the transport sector is thought to account for over 20% of these emissions. Mandatory fuel economy and/or greenhouse gas emissions standards for light-duty vehicles are already in effect for more than 70% of the global new vehicle market.
