ASH / ASH CONTENT

Ash forming deposits are considered to be undesirable contaminants and impurities in the oil. Hence low ash content oils are required to provide an effective protection against the wear in any system. High ash content in the oil will cause deposits in the combustion chamber with resultant spark plug clogging which in turn will cause engine misfire and knocking. High ash content in the system can cause clogging of the filter, block the fine pores of the filters, causing loss of power and exhaust back pressure.

ATLAS LAB tests Ash in their laboratory by using the following test methods:
