hmmm plugged solid cats.

suggest you always buy your gas from a high volume station, high volume supplier.

I've had that happen ONCE,, right after I bought from a low volume Citgo station...which in my area is low exposure.

Some of those had one cat on the Y pipe, some had two. Either way, its an expensive proposition. Change all the O2 sensors while your at it.

My question would be plugged or melted into a lump? If the engine was misfiring and it caused the meltdown, a new cat could soon be toast also. The other problems need to be fixed ASAP if that's the case.

Hi Bob and Backyard mechanic,

Got nothing to do with the price... has to do with quality control.. and road-side stand type stations or low volume brands often get screwed up.

My experience was, cat melted into a ball, right after low vol off brand fill-up. And I did nothing but put on a new cat and it was fine.

Pick a low-price market leader that's everywhere and the gas will be ok.

Around here, that's Speedway.

BTW, I absolutely hated BP up to now.. but since they've started using Arco's formula it runs great in my cars. Still only go to hi-vol stations, tho.
