I have a 98 Durango and as of a month ago im only getting about 90 miles to a tank! I don't seem to have a gas leak though. What else could cause this?

You sure your fuel guage is working correctly?


Check your tire air pressure. How old is your O2 sensor? If it's ten years or 100,000 miles, replace it.


Make sure all that surplus gas isn't getting into your oil. Sounds like it's obviously running really rich. Some of them mopars you can turn the ignition switch on and off so many times then the check engine light will flash a sequence telling you in code which sensor is bad. Bad sensor is my guess. Some parts houses will scan it for u free.

if its a carbureted engine try getting it re-tuned. and its ecu then there must be some leakage or check if your engine is may be taking excess air( intake manifold).
