Nissan Juke low fuel mileage issue with no identified solution on Nissan Juke

Some Nissan Juke owners report experiencing low fuel mileage issues, which may be attributed to various factors. These include discrepancies in fuel consumption test results, where controlled tests indicate a mileage of 47 MPG under optimal conditions, yet daily driving routines, especially in city or country settings, yield averages of only 45 to 46 MPG. Additionally, some owners have noted symptoms of fuel pump failure, such as engine stalling and unusual noises, which can significantly impact performance. Diagnostic trouble codes, like P2096, are also reported to affect the air-fuel mixture, leading to poor fuel efficiency. Engine misfiring due to faulty coil packs, spark plugs, or fuel injectors can trigger the check engine light and further reduce mileage. Furthermore, aggressive driving habits have been linked to lower fuel efficiency, with some drivers reporting averages as low as 27.6 MPG. Seasonal changes in fuel blends, particularly the switch to winter fuels, have also been noted to decrease mileage by 3-4 MPG. Addressing these issues promptly is essential for improving fuel efficiency in the Nissan Juke.
