  • O2 sensor?

    Does the O2 sensor help with better fuel economy??? Where is the cheapest, does C1 install them? and sell them? I have bad fuel economy, half tank I get about 200 kms.

    Could be o2, coils or MAF (most likely) - I'd just get the dealer to diag it since you're probably still in warranty?

          Your O2 sensor should be ok, unless you are getting check engine lights or other fault codes.

          I get about 240 km on 1/2 a tank, so 200km sounds right around normal to me.

            Yeah 200kms on half tank and a VR6 does not sound that bad.

                  600km/tank is easy if you're talking highway (that's around 30mpg). Driving at the track, I managed to get 14mpg with a 1.8T.
