Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Therefore, test results indicated a low insolubles reading. Common causes of engine oil thickening include highly oxidized oil, glycol contamination, thermal degradation and severe soot contamination.

Conclusion Upon speaking to the laboratory personnel, it was discovered that when the pentane insolubles test was run, the additives dispersants in the oil appeared to have kept the soot suspended in the sample.
