The automotive and lubricant industries have been placing increased emphasis on the fuel economy benefits of today′s modern passenger car motor oils.The current ILSAC GF-4 specification has more stringent requirements than previous ILSAC specifications,and the proposed future ILSAC GF-5 specification is looking at further improvements in the lubricant′s fuel economy performance.To address these needs,Afton Chemical has developed correlations between the rheological and frictional properties of oils and fuel economy measured in engine and field tests.In this paper we will present correlations between lubricants′ physical properties and fuel economy measured in vehicles and engine tests.These tools have been used to develop current commercial oils which are being used extensively to meet today′s OEM needs.

This paper we will present correlations between lubricants’ physical properties and fuel consumption measured in vehicles and engine tests.These tools have been used to develop current commercial oils which are being used widely to meet today’s OEM needs.
