Hi all -
Does anyone know what the typical acceleration of catalytic converter degredation is with high tbn high anti-wear additive (ZDDP) oils vs. something like amsoil/edge/M1 EP?. For instance, would say 1.5 quarts of consumption in 13,000 miles cause a noticeably reduced life for a catalytic converter (given that the consumption occurs in normal driving conditions)?
