Choosing the right fuel type for your Mitsubishi Eclipse Cross is essential for maintaining optimal engine performance and efficiency. Mitsubishi recommends using high-quality unleaded gasoline with an octane rating of 87 or higher to ensure smooth operation and prevent engine knocking.

Why Fuel Quality Matters

Using the correct fuel not only supports the engine’s performance but also contributes to better fuel economy and reduced emissions. Lower octane fuels can cause knocking and may damage engine components over time, while high-quality fuels contain additives that help keep the engine clean and running smoothly.

  • Regular Unleaded Gasoline (87 octane minimum): Suitable for most driving conditions and recommended for everyday use.
  • Premium Gasoline (91 octane or higher): May be used for enhanced performance, especially in demanding driving scenarios, but is not required.
  • Alternative Fuels: The Eclipse Cross is not designed for ethanol blends higher than E10; using higher blends can affect engine performance and warranty coverage.

Tips for Maintaining Engine Performance

  1. Always fill up at reputable gas stations to ensure fuel quality.
  2. Regularly check and replace your air filter to maintain proper air-fuel mixture.
  3. Follow Mitsubishi’s recommended maintenance schedule for tune-ups and inspections.

By following these fuel recommendations and maintenance tips, you can enjoy the full potential of your Mitsubishi Eclipse Cross engine, ensuring reliable performance and longevity.
