hey fellas i brought a ve calais 6.0 about a week ago and it seem to use a fair bit of fuel, averages around 17 ltrs per 100 ks, its done 86000ks and i looked at the 02 sensors and they look like they have never been changed, so my question is how long are they designed to last from factory? could a faulty 02 sensor be my fuel problem? ive checked the afm and air filter and they basically look brand new clean as a whistle

all help much appreciated

cheers ricky

And I know it's not WAY put there but just a bit confusing when I see everyone else posting about 13.8 and I know it's a v8 I didn't buy it for ecconomy but I though it would be better than this

Yea about 70 30 but again I thought being a six speed it would be better than my vt ls1 which only uses about 14 around town

2001 HSV VXII Clubsport R8, Cam & Heads, OTR, Full exhaust, tune, 306.7rwkw + 130,000km on the clock with the same O2's.

Having said the above I have a mate of mine that has gone through 3 set's of O2's in less than 50,000kms, so it's hard to say how long they should last.
