alright.. I guess I could start off that the car has 233,000 KM (145,000 miles)
its a 2000 grand am GT.

now, I drive normal.. and I get about 315-320km to 40 Liters (I hate doing conversion too LOL)

thats about 200 miles to a tank. 40 liters = 11 liters assuming 1 Galon = 3.8Liters

I put new plugs/wires.. car idles fine.. I'm thinking O2 sensors (no check engine light though) or clogged cats, or maybe injectors.

any known probs @ this age? if you saw the car.. you'd never guess it had tht high milage. obviously, it was all highway :)

Fuel filter, air filter???

Have the injectors professionally cleaned.
