The car does contain some Pt metals in the cat, I have no idea which metals the cat in my car has. It could be Pd/Rh, Pt/Rh or even some other combination like Pd/Pt/Rh. I guess that it is PGM nanoparticles on a mixed CeO2/ZrO2 layer on a Al2O3 honey comb but I have also seen some cats which have the PGM nanoparticles on stainless steel mesh.
Should I leave him?
