- Holden VZ V6 AUTO Berlina Wagon
Hello all,
Im generally pretty savvy with cars and the working parts of them. but with things getting newer and more digital im not sure where to put my finger to fix it.
I owned a nice 5spd manual vy v6 storm ute before this vz wagon and i know that on the highway i averaged around 8-8.5L/100km and around town was between 11.5-14L/100km depending how hard i drove it.
i bought this vz a few months ago and fuel economy has been pretty average since (on the bad side)
it had a miss when i got it, and bought a basic diag tool (autel al319) to help find the isssue. it told me that O2 sensor issue post cat and left bank i think it was was lean at some point.
so instead of just going out and spending heaps of money on O2 sensors and crap i went through the extensive service history i managed to get a hold of and found the plugs hadnt been replaced for 80,000k's. so replaced then and miss was gone.
now back to fuel economy, when i drove from brisbane to cairns i was expecting decent L/km's the whole trip up, well under the 10L/100k. i didnt have much onboard and only had myself and 3yo in the back. over the whole trip i averaged about 12L/100km. which is really crap considering we did one overnight and stopped on the way for usual fuel and food.
now the lowest i managed to get was between townsville and cairns and it didn't drop below 10L/100km. around town im averaging around 16-20L/100km which is just rubbish. what should i do next? would this be causing by O2 sensors? or do these things need a "tune" once in a while? i didnt think they did since it was all automatic with the sensors etc.
the diag tool isn't posting any errors any more so i have nothing to work on.
any help or advice would be much appreciated. thanks ppl.
