Ishida's X-ray inspection technology can detect both
metal and non-metallic
fragments; bone, shell, glass, high density plastic, stone, rubber and
more.
If you are replacing worn bearings, you don't want to reuse your engine oil no matter how new it is, because it will
more than likely have
metal fragments from the old bearings in it... no sense in putting
metal particles back into your engine and having all those wear items thrown into the mix.
