A new category of motor oil is on the way: oils which bring about a reduction in fuel consumption. American car manufacturers are cooperating with the mineral oil industry to develop standard tests for checking this property. The common aim is the maximum utilization of dwindling oil reserves. Multigrade engine oils, which result in better fuel consumption than single-grade oils, have been on the market for some years. Today these oils are being further improved by the addition of admixtures for decreasing friction, in order to achieve further savings in fuel. This paper describes the programme for developing friction reducing admixtures (friction modifiers) which is being undertaken with a view to producing commercial motor oils which satisfy the requirements both of the engine manufacturer and the mineral oil industry. The results of laboratory tests, test-rig engine tests and field tests are reported. The authors also give details of the position of a joint programme for the standardization of engine tests and reference oils for the purpose of international specification of fuel-saving motor oils (fuel economy oils). The method which is currently in the foreground is described and the results given. (TRRL)
