Directions for Superzilla in Gas Tanks
For at least 10 years we have used Superzilla successfully to remove the buildup on fuel injectors, carburetors, and carbon from the top end of engines. Superzilla has been used in cars, trucks, tractors, lawn mowers, jet skis, snowmobiles, rototillers, chain saws, and outboard & inboard motors in boats. For trucks and cars, we add Superzilla every 15,000 to 20,000 miles. This is when we usually notice the vehicles running rough or getting poor fuel economy.
We have two customers who couldn’t pass their emission tests because their catalytic converters were plugged. In both cases they applied two applications of Superzilla at the maximum amount and it cleaned out the catalytic converters enough so they could pass their emission test.
We have a GMC Sierra 1500 with 315,000 miles and not one part on the exhaust system has been replaced including the catalytic converter. The GM dealer told us normally catalytic converters are replaced between 100,000 and 150,000 miles.
