ETHYLENE GLYCOL IN USED ENGINE OIL: ASTM D4291
ETHYLENE GLYCOL IN USED ENGINE OIL: ASTM D4291EXPLANATIONLeakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method provides for early detection to prevent coolant from accumulating ...
