Is the engine running smoothly, does the car feel bogged down, is it running unusually hot or cold, any smoke signs, color of the smoke, stumbling, hesitation, missfiring periodically/random, backfiring?

I am not familiar with your vehicle, do not know if it is multiport fuel injected, or if has s single injector on a throttle body, etc.

Things that contribute to poor gas mileage:

Mechanical condition of the engine: Low compression, Valve Timing, Clogged exhaust system.

Tune Up related items: Sparkplugs, ignition timing, air filters, fuel filter, O2 sensonr, engine coolant temperature sensor (if equiped with one), thermostat, injectors condition, other sensors being off.

Tire Pressure, Alignment, wheel bearing conditions, brake dragging. etc.

Please provide us with more information, such as how many miles you ran during those 2-3 days.

Good luck,

AS
