My RX has 66k and still runs strong. Despite that, should I still seafoam it?

Any idea what the seafoam does to the CAT?

 

if it has no issue. then no.

 

Seafoam won't really harm anything but whether you need to do this as preventive maintenance? not sure

It won't hurt the cat if you follow the procedure

 

No emissions testing ? Who cares about the CAT

There should be no problems with the CAT...the Seafoam will burn off in short order

I would pull the airpump fuse, or plug ( easier) though if you are re-starting it cold to it doesn't turn into a torch

 

seafoam is excellent. enjoy the smoke show
