    Does the o2 sensor need to be replace even if the indicator light did not light up?
    Will it help fuel efficiency?
    What type of o2 sensor to buy?

    Mark, i had them replaced - when the orange engine light came on and stayed on - They are expensive - there is 2 of them - invoice says $940 and $1040.
    In australia, i had to wait 6 weeks for them to arrive, but i was told i could still drive the car, while i waited for them to arrive. It is unerving, seeing the warning light on all the time, but i didnt notice any drop in fuel consumption at all - and the engine still ran normally, with no change - they are of course, best to replace, but you can still drive the car normally, with no change in performance. hope that helps. They may be cheaper where you are -

    Hi Dwayner, the O2 sensor is way too expensive. In Singapore I could get it for about SDG$100.
    Thanks for the sharing your experience. Looks like I will wait for the O2 sensor warning light to light up before I replace them.
    There are a lot of parts in Singapore that are cheaper, let me know if you need some parts and I will check if Singapore has it... cheers.
