Analysis of Engine Oil Deterioration under Bio Diesel Fuel Use

The research discussed in this paper clarified the effect of biodiesel fuel (BDF) on two effective deterioration indexes of engine oil, the base number (BN) and the oxidation induction time (OIT). The results of rig tests of oil deterioration using an engine oil mixed with BDF showed that BDF, which contains a large number of unsaturated bonds, accelerates engine oil deterioration.
