Testing the Gasoline Dilution Rate of Gasoline in Engine Oil in Accordance with ASTM D3525 and Japan Petroleum Institute Standard JPI-5S-24

If fuel such as gasoline or diesel is mixed in the engine oil, the viscosity decreases and the original performance of the lubricating oil cannot be obtained. The fuel dilution rate is used as an indicator of oil change because it enables us to determine the state of deterioration of engine oil. 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 measurement examples of gasoline dilution rate in engine oil based on ASTM and JPI.
