Facing an upcoming emissions test can be nerve-wracking for any car owner. Many drivers rely on the check engine light and OBD2 scanners to gauge their vehicle’s health. But what if your car shows no check engine light and your OBD2 scanner reports no issues? Does this guarantee a pass on your emissions test? Not necessarily. Even a car with no check engine light on and a seemingly clean OBD2 scan can still struggle with emissions. This is where preventative maintenance and smart solutions come into play.
One car owner discovered a powerful way to significantly improve their emissions results, even in a 30-year-old vehicle with original parts. Prior to their December 2023 smog test, they used a product known as Cataclean as a preventative measure. This wasn’t a case of reacting to a failed OBD2 scan or a lit check engine light; it was about proactive care to ensure optimal performance and minimize emissions.
The results were impressive. In previous years, their Hydrocarbon (HC) levels were nearing the state’s acceptable limit, and Nitrogen Oxide (NOx) was gradually increasing. However, after using Cataclean, HC emissions plummeted by a remarkable 50%. Carbon Monoxide (CO) levels, already low, still showed improvement, and NOx emissions decreased by 33% at low RPM and an astounding 50% at high RPM.
Beyond just the numbers, the driver also reported a noticeable improvement in the vehicle’s overall performance. This highlights that addressing potential emissions issues, even in cars that appear fine to an OBD2 scanner, can have broader benefits.
Cataclean, readily available online, is suggested for use as a preventative measure. The user in this instance incorporated it into their routine every three months leading up to emissions tests. For optimal use, it’s recommended to add Cataclean to a quarter tank of gasoline and drive until you’re close to needing to refuel. Alternatively, a double dose can be added to a half tank.
If you’re aiming to pass your emissions test with flying colors and ensure your vehicle is running its best, consider preventative solutions like Cataclean. Even if your car shows no immediate red flags with a check engine light or OBD2 scanner, proactive maintenance can make a significant difference in your emissions results and overall vehicle performance.
