Have you driven your Oshan X7 extensively on low-quality fuel, which might have contributed to catalytic converter degradation?

Unleaded fuel with impurities can damage the converter over time. Are you using regular fuel o r high-octane, and do you think it has affected your vehicles emission system?

Yes, repeated use of low-quality, adulterated fuel especially from unauthorized petrol stations has been linked to converter fouling. Users who consistently used high-octane fuel from reputable stations reported fewer catalytic issues and better overall performance.
