[kingvt]

hey guys i just wanted to ask lately my vy has been burning alot of petrol. im struggerling to get goot ks out of a full tank. im roughtly getting just over 300 and i have spoken to many others and their getting bout 450 +. i heard that the oxygen sensors might be the problem. do they play a roll in this situation or could it be something else. any help would be great thanks
