The oil in the piston second land of gasoline engine was investigated in terms of the degree and factors of the degradation. The land oils was sampled by using link system during engine operation. The results of several investigations indicated that the degradation degree of the land oil was significantly higher than that of crankcase oil. The land oil was confirmed to be exposed to high temperature and blowby gas including NO_x. The total base number of oil was proved to decrease with the oil temperature and NO2 concentration by NO2 bubbling test. In addition, these effects were found to be accelerated by reducing the volume of oil.
