Popis:	The assessment of engine oil useful life is an important step in the development of future low-phosphorus, catalyst-compatible, and long-drain engine oils. This paper describes the development and application of a new laboratory screening test, the Ford oil ageing test (FOAT), for the assessment of engine oil useful life. FOAT simulates the Sequence IIIE engine dynamometer test and evaluates oils on the basis of viscosity increase. It correlates well with both single- and double-length Sequence IIIE test results. FOAT allows for inexpensive screening of candidate oils prior to engine tests and is currently being used in the evaluation of future low-phosphorus engine oils. This comparative study has demonstrated that low-phosphorus, catalyst-compatible engine oils can be formulated to provide a similar useful life to current commercial long-drain oils.
