i just sold my 6 cylinder vp and bought a vs 5lt wagon. i knew my petrol cost would go up with an 8 but i was suprised when i only got about 300kms out of a tank driving it normally (not thrashing the b-jesus out of it at all). Is this normal? If not what could be causing it and how can i fix it?

air filter, fuel filter can cause a bit of petrol wastage but the only thing i can think of is cleaning the throttle body because that is meant to help fuel economy

maybe o2 sensor cos they can cause bad milage too,maybe ur injectors need cleaning, does the car go like it should or is it a bit sluggish

it goes good but its lacking a little in the lower end of the revs, but once it gets up round 3000rpm it almost feels like it hits boost or somfin.

Sounds really low. How are you measuring your km's to a tank?
