Something must be wrong!

[Lewis]

Alrighty, heres hoping you guys can shed some light.

I have an 2002 Liberty RX 2.5, the one with the 55/60L fuel tank. It's Automatic. Now, my friend who has the same car but in manual gets around 500km's to a full tank, whereas at the moment im struggling to get 300km's. Surely there wouldnt be a 200km difference in transmission type alone?

Basically i think there might be something wrong, i should be getting more than 300km's to a tank, seeing as though even when i try to drive as less aggresively as possible, rarely ever going above 3500rpm, i still struggle to get 350km to a tank.
Redbook says it should use 10L/100km city driving, therefore i should still be getting closer to 500km's rather than 300!


Does anyone else have this issue? what kind of km's are other people getting out of their car? What can i do to fix this problem!?

Please help me as 70 bucks a week on petrol is a lot for a 17 year old, especially when im only getting 300km's to a tank!!

edit- its only done 150,000km's if that makes any difference? had a service about 7000 km's ago

So in the 150k service they did the spark plugs and all oils and fluids (engine, auto, front and rear diff, coolant)?
If that's been done, I'd swap the O2 Sensor and run 3 or 4 tanks of 98RON petrol (1st tank I'd put some injector in with it too) and see how that goes.
