Abstract: Activation energy, W, is determined from oil (16) conductivity measurements to thereby provide engine oil condition from a known relationship between viscosity and W. Changes of W at a given temperature as the oil ages are reflective of changes in viscosity of the oil at the same given temperature, wherein changes in W at different temperatures are reflective of changes of viscosity at those respective temperatures as the oil ages. To determine viscosity, the temperature dependence of the oil's conductivity (20, 22) is measured to deduce the value of W at a given temperature. W is monitored as the oil ages (28, 38). W may also be determined through the ratio of the oil conductivities at two different temperatures by techniques well known in the art by which the viscosity may be determined as the oil ages.

Abstract: A method by which contaminant (soot) content in Diesel engine oil is determined using electrical conductivity measurements of the Diesel oil at a high frequency (150-160), or by which contaminant (soot and/or water and/or anitfreeze) content is determined using the ratio of electrical conductivity measurements of the Diesel oil at a high frequency to the electrical conductivity measurements of the Diesel oil at a low frequency (170-192). Both the conductivity ratio and the high frequency conductivity are essentially independent of the brand of oil. High frequency is defined to be above 2 MHz whereas low frequency is defined to be D.C. to about 1 kHz.
