 note = {We originally developed a preparation method of target sample for automobile engine lubricating oil (liquid sample) specifically designed for in-air PIXE analysis with Helium ions. In the developed preparation method, target samples were fixed by making the oil sample sandwiches with 1% collodion solution based ethanol. With this analytical method, elements such as Mg, Al, Si, P, S, Cl, Ca and Zn can be detected from the oil samples, where Mg, Si, P, S, Ca and Zn were the elemental components of the oil additives., Proceedings of the XI International Conference on PIXE and its Analytical Applications　（PIXE2007)},
