Abstract:
With an increasing demand for superior emission and fuel economy standards in modern engines, the automobile industry must be prepared to supplement these changes with the development of higher performance engine oils. Before an engine oil can be introduced to the consumer market, however, the oil must undergo significant testing for several properties, according to standards set by the American Petroleum Institute (API) and International Lubricant Standardization and Approval Committee (ILSAC). One such property is the oil’s viscosity at low temperatures, which may cause catastrophic engine failure from poor pumpability and deposit formation.
The Romaszewski Oil Bench Oxidation (ROBO) test, developed for the API SN and ILSAC GF-5 specification, is a strong alternative to the Sequence IIIGA test that has long been used to evaluate cold-temperature viscosity of an aged oil. The ROBO test is able to duplicate the oil aging mechanism of Sequence IIIGA test results in a fast and cost-effective manner, while allowing for the assessment of oil viscosity with several other test methods. This paper is an attempt to be a comprehensive literature review on the work done on the ROBO test method so far. This paper will therefore take a close analysis into the development and applications of the ROBO test, as well as present a comparison with the Sequence IIIGA test method. We will discuss the various advantages and any possible drawbacks regarding the use of ROBO. We will also discuss the current and future potential of the ROBO test, including its use in the development of future oil specifications such as ILSAC GF-6.
