Infiniti QX60 2014-present Fuel System Specifications

The 2014-Present Infiniti QX60 is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. While it can operate on regular unleaded gasoline with an octane rating of 87, using premium fuel is recommended for optimal performance and efficiency. Using lower octane fuel may result in reduced engine power and fuel economy. Always refer to the owner's manual for specific fuel requirements and avoid using fuels with additives or ethanol blends exceeding 10%.

The fuel system in the Infiniti QX60 requires regular maintenance to ensure optimal performance. This includes replacing the fuel filter every 30,000 to 40,000 miles and inspecting the fuel lines for leaks or damage during routine service. Additionally, it is recommended to use fuel system cleaners every 15,000 miles to prevent carbon buildup in the injectors. Always follow the maintenance schedule outlined in the owner's manual and consult a certified technician for detailed inspections and servicing.

To replace the fuel filter in a 2014-Present Infiniti QX60, first, ensure the vehicle is parked on a flat surface and the engine is cool. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Locate the fuel filter, typically near the fuel tank. Disconnect the fuel lines and remove the old filter. Install the new filter, ensuring it is securely connected and the arrow points toward the engine. Reinstall the fuel pump fuse and start the engine to check for leaks.

If your Infiniti QX60 experiences fuel system issues such as poor performance, engine misfires, or difficulty starting, begin by checking the fuel level and ensuring the fuel cap is properly tightened. Inspect the fuel filter for clogs and replace it if necessary. Use a diagnostic tool to check for error codes related to the fuel pump or injectors. If the issue persists, consult a certified technician for a thorough inspection and repair to avoid further damage to the fuel system.

To optimize fuel efficiency in your Infiniti QX60, use premium unleaded gasoline with an octane rating of 91 or higher. Maintain a consistent driving speed and avoid aggressive acceleration or braking. Regularly check and maintain proper tire pressure, as underinflated tires can reduce fuel economy. Keep the vehicle well-maintained by adhering to the recommended service schedule, including timely oil changes and air filter replacements. Additionally, reduce unnecessary weight in the vehicle and limit the use of air conditioning when possible.
