Why has fuel consumption increased?
Before blaming one component, compare similar trips and conditions. Traffic, weather, load and driving style can also change fuel use.
What it may indicate
- Fuel use remains higher on comparable trips
- Power loss, rough idle or warning lights appear
- Tires are underinflated or show abnormal wear
What to check
- Check tire pressure and condition
- Review maintenance and filters according to the manufacturer
- Diagnose engine and sensors if the change persists
When to prioritize an inspection
If higher fuel use comes with a strong fuel smell, smoke, leaks or engine faults, prioritize an inspection.
