Solder-It (CAT-1) Catalytic Converter Cleaner - 16 oz.
Catalytic Converter Cleaner helps eliminate "rotten egg" odor. A clogged or restricted Catalytic Converter can decrease fuel efficiency, rob horsepower, cause engine overheating and premature engine wear. Catalytic Converter Cleaner extends time between tune-ups, increases fuel efficiency, and extends the life of your converter.  Directions: Add contents to your gas tank (funnel recommended) and drive until nearly empty before refilling your tank with fuel. Repeat every 6,000 miles or twice yearly. For faster results, run engine until fully warm. Remove air cleaner with engine running at a fast idle. Pour contents through the carburetor throat. Replace air cleaner.
