Testing the Dilution Rate of Gasoline in Engine Oil in Accordance with ASTM D7593

If fuel such as gasoline or light oil is mixed in the engine oil, the viscosity decreases and the original performance of the lubricating oil cannot be obtained. By measuring the fuel dilution rate, it is possible to determine the state of deterioration in engine oil, so the fuel dilution rate is regarded as an indicator of oil change. Test methods such as ASTM D 3524, ASTM D 3525, and ASTM D 7593 are specified for measuring the fuel dilution rate. In this application news, we introduce an example of rapid analysis of the dilution rate of gasoline in engine oil using a backflash system based on ASTM D 7593.
