INFLUENCE OF ADDITIVES ON ANTI-OXIDATION PERFORMANCE OF ENGINE OILS BLENDED WITH BIODIESEL

Abstract

Abstract: The simulated oxidation test method of engine oils blended with biodiesel was established referring to GFC Lu-43-A-11. Based on the oil formulation that fits the ACEA C3 5W-30 oil sequence, the influence of additives such as antioxidants, ZDDPs, detergents and dispersants, on anti-oxidation performance of engine oils containing biodiesel was studied. The results demonstrated that the additives such as amine antioxidants, secondary alkyl ZDDPs, high TBN detergents, high molecular weight succinimide dispersants showed better anti-oxidation performance of engine oils containing biodiesel.

Key words: engine oil, biodiesel, oxidation performance, additives
