Tech Tip: Help Your Customers Pass Emissions Testing

Simple steps like cleaning the system may be all it takes.

When customers are concerned about their vehicles passing upcoming emissions tests or are wondering what to do after their vehicles fail smog checks, there are a few simple, cost-effective steps you can recommend.

Major mechanical malfunctions aren’t the only reason vehicles fail emissions tests. Suggest that your customers:

  • Perform their own visual inspections to check for any missing emissions equipment and replace as needed. Replacing a lost gas cap or one with a bad seal is easy. If the car came with a catalytic converter originally but no longer has one, they’ll need to replace it themselves or have a new one installed.
  • Address any obvious fluid leaks. Some inspection facilities won’t test vehicles with fluid leaks due to safety concerns. A pop-and-pour chemical solution can usually handle this issue. Unsure where the leak is coming from? An all-in-one solution like Bar’s Leaks One Seal (P/N 1334) can take on leaks in engines, transmissions, and power steering systems. 
  • Clean the emissions, fuel, and exhaust systems. A dirty catalytic converter or oxygen sensor can cause the vehicle to fail its test, even when the components are mechanically sound. Rislone CAT CompleteTM Fuel, Exhaust and Emissions System Cleaner (P/N 4720) scrubs away contaminants, soot, carbon build-up and oily residue from fuel injectors, combustion chambers, catalytic converters, EGR valves, and oxygen sensors. 
  • Clear the check engine light. In many states, an illuminated check engine light (CEL) equals automatic emissions smog test failure. Rislone CAT Complete will clear P0420 and related OBD codes. In fact, Rislone guarantees that when CAT Complete is used properly, the CEL light will turn off and the vehicle will pass emissions testing. Visit for details.
  • Catch up on routine maintenance. Consider an oil change, new fuel filter and fresh spark plugs, if needed. 

As with any test, proper preparation is the key to success. Help your customers prepare their vehicles for their next emissions test, and at the same time you’ll be helping them maximize their vehicles’ power and performance.

Rislone CAT Complete works on all fuel-injected, direct-injected, carbureted, turbo, GTDI, Ecotec and EcoBoost gasoline engines. Installation is easy and the bottle is designed to work in all gas tanks, including standard, obstructed and capless (no fuel cap) systems. It’s EPA registered, exceeds EPA compliance performance criteria and is legal in all 50 U.S. states.
