Well i've reset the ecu three times, everytime i reset the ECU and try driving normal it gives me great consumption till about half a tank. Then for some weird reason it seems to go back into the 16/17L per 100km. My mate used the OBD and said the o2 sensors seemed fine but I'm not convinced. Maybe worth it to try running fuel injector cleaner again??

I really am stuck with this issue, i drive quite a lot and this is really burning a hole in my pocket, i use Standard unleaded but every so often i fill up with the premium to keep it clean.

Could be the O2 sensor (aka oxygen sensor, aka lambda sensor) has gone bad, that can effect consumption. How are you calculating consumption? Onboard computer or comparing fill ups?

I've calculated consumption both by the onboard computer and comparing fill ups, because it's been happening for about 6 months now. so you think the o2 sensor ? anyway to check this, will an OBD be able to determine if the sensor is not working properly?

Hi, Im quite new to the forums here.

I've got a 2005 MCV36R Toyota Camry Ateva now my fuel economy is around 17.8L/100km = Pretty crazy i think for a camry, either im a crazy driver or theres something wrong. I've tried fuel injector cleaners a few time ran the engine out all the way with the stuff, didn't really impact it. Any other ideas to what it could be?
