OK, really need some advice.

My 92 Trooper 3.2 V6 Auto gets about..let's see...300kms (186miles) to a full tank city, and maybe about 400kms (248miles) highway if I'm lucky. Seriously, it's like the fuel's leaking out when I park or something (it isn't!).

The engine runs like a top (251,00 kms and going strong; barely broken in!), pulls like a rocket, starts on a dime, never pushes blue (knock on wood).

Anyway, here's what I've done so far:

-searched the forum
-changed the O2 sensor
-replaced all fluids and filters
-kept the tired well inflated

I also tried driving more gently, but it made almost no difference: hard driving (with the Power drive engaged) or soft, it's all the same.

Any ideas what to try next? (aside from selling the old girl?)
