Poor fuel economy
Higher fuel usage should be checked against consistent measured fill-ups and routes.
Understanding the symptom
Higher fuel usage should be checked against consistent measured fill-ups and routes.
Possible causes to investigate
Tire pressure; driving pattern; short trips; faulty thermostat; engine faults; vehicle load.
Safe observations
Calculate km/L or MPG across several fill-ups; note tire pressure and warning codes.
When to stop and get help
Fuel odor, visible fuel leaks or persistent misfire require prompt attention.
A symptom alone cannot establish a physical diagnosis. Arrange competent inspection where safety is uncertain.
