Default symptoms of a bad o2 sensor..

I'm not expert on the subject but I think bad mileage, acceleration, etc. It deals with mixing the correct air and fuel ratio into the engine for the most efficient "power" stroke.

I don't think it would be related to burning oil, unless the oil coked the sensor itself and damaged it. But a bad O2 sensor wouldn't make your car burn oil I don't think.

Oh OK I see what you are asking now...sorry my bad!!

I don't know to be honest, it would depend on your driving style and conditions, if I do the math that works out to about 20 MPG, if you're doing mostly city driving that's pretty close, my 60% city, 40% highway mpg is around 22-24 or 600 km.

Hey Wheels....for my driving style, kinda cool, not driving the car like i'm in grand theft auto!! haha i do a good mix of highway and city, but it's not always a smooth flowing highway, we drive into the city and back everyday and there is usually traffic...just yesterday i was stuck for about an hour and mostly at a dead stop...so there you go...
I have driven once straight highway and got about 600-650km on the tank....not too bad actually...i used to get that on the caprice too but the car used about an extra 30 liters about..so it did drink a bit more...
thanks againn.ciao

Usually a light comes on before you see any issues.

Tech..will the light still come on seeing as i only have 1 oxygen sensor not 2? if it does come on where there is a problem (even with 1) then i guess i'll just drive until it does come on...thanks
