I drove 200 kms today at 100 km/h (using cruise) left my foot out of the equation and drove nicely. This was all on the highway and I still burned a hair under half a tank of gas

i asked this before (about the mileage)

but im wondering if anyone thinks the O2 sensor may be the culprit.

i know it sends out signals and trips the check engine light if it gets "out of range" but is it possible for it to be out of range enough to screw my mileage and not to set off the light??

Maybe I just dont know well enough how the system works..
