OBD code P0420 indicates a problem with the catalytic converter's efficiency, and while using 87 octane fuel in a 2010 Cadillac SRX is not the primary cause of this code, it can potentially contribute to performance issues in some cases. Lower octane fuel may lead to incomplete combustion, which could generate more emissions and affect the catalytic converter's function over time. However, other factors such as a failing catalytic converter, oxygen sensor issues, or exhaust leaks are more likely to be the root causes of the P0420 code. It's advisable to diagnose the specific issue using a professional scan tool and inspection.
