Sludge Problems
March 23, 2010
Sludge formation is caused by oil being subjected to abnormal operation conditions such as high heat, excessive blow-by gasses, glycol contamination or poor crankcase ventilation. Sludge formation, if severe enough, can block the oil passages and oil pump pick up screen, resulting in oil starvation.
AMSOIL Synthetic Oils
have better oxidation resistance, detergency and dispersancy than conventional petroleum oils, and they do a better job of resisting sludge. However, they will not stop sludge formation under abnormal engine operating conditions. The use of synthetic oil for the best possible engine protection is endorsed by Consumer Reports.
