I just replaced my passenger's side catalytic converter this weekend due to it being completely broken apart on the inside. My truck only has 106k at the time of the failure (mileage went up because we were on a road trip when it happened). I haven't seen a cat go bad this soon in a while. My question is this, I use Lucas UCL every fillup (have the gallon), could this lead to catalyst failure? Also, if the passenger side is this bad, is the driver's side also bad?
Thanks!!
Thanks!!
