Anybody got anything to say, good or bad, about catalytic convertor fuel additives that claim to clean the cat? Fuel and oil have lots of additives in them that are designed to keep your engine clean so it it worth pouring $15.00 worth of chemicals into the tank in the hope it may reduce pollution?

 

if your CAT is clogged then its best to take it somewhere to have the entire system cleaned out, a fule filter replacement will help as well. the additives you get in the store work well but dont necessarily get everything.
