Maintaining the O2 sensors in your Mitsubishi is crucial for optimal performance and fuel efficiency. Regularly check for signs of wear such as poor engine performance, increased emissions, or a check engine light—these may indicate the need for a replacement. To extend their lifespan, avoid using leaded fuels and ensure your engine is running properly to prevent contamination. When selecting new O2 sensors, opt for direct-fit or universal sensors; direct-fit offers ease of installation while universal sensors may require additional fittings. High-quality materials like zirconium or titanium increase durability. For seamless installation, always follow the manufacturer's guidelines and consider applying anti-seize compound to the threads if recommended.
