Jeep Compass 2007-2016 Fuel System Specifications

The 2007-2016 Jeep Compass is designed to run on regular unleaded gasoline with an octane rating of 87. Using higher octane fuel is not required but may improve performance in certain conditions. Diesel or ethanol blends above 10% (E10) are not recommended as they can damage the engine and fuel system components.

The fuel system in the Jeep Compass requires regular maintenance, including fuel filter replacement every 30,000 miles, inspecting fuel lines for leaks or damage, and using fuel system cleaners every 15,000 miles to prevent buildup. Additionally, ensure the fuel cap is tightly sealed to maintain proper pressure and avoid the check engine light.

To replace the fuel filter, first, relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Locate the fuel filter, typically under the vehicle near the fuel tank. Disconnect the fuel lines using a line disconnect tool, remove the old filter, and install the new one. Reconnect the lines and reinstall the fuel pump fuse. Start the engine to check for leaks.

Poor fuel efficiency can result from dirty air filters, low tire pressure, or a malfunctioning oxygen sensor. Check and replace the air filter if needed, ensure tires are inflated to the recommended pressure, and use an OBD-II scanner to diagnose any error codes. Regular maintenance, such as spark plug replacement and fuel system cleaning, can also improve efficiency.

To optimize fuel performance, maintain a consistent driving speed, avoid excessive idling, and use cruise control on highways. Regularly replace spark plugs, air filters, and fuel filters. Ensure tires are properly inflated and use high-quality fuel. Additionally, reduce vehicle weight by removing unnecessary items from the trunk or cargo area.
