Hey guys I have a quick question.
The previous owner of my car had a Toda racing exhaust system installed, would that affect the O2 sensor which could be the reason for my terrible fuel inefficiency?
I just poured in a bottle of fuel flush today so if the fuel inefficiency doesn't get any better than I'm assuming it's the O2 sensor.

Could it be damaged or just dirty?

How many km's are u getting per 10L? Might be spark plugs.. If your averaging 100km/10L then you're fine

No where near close 100km/10L, I'm getting about 320KM to a full tank.

are you sure its a full tank? ive gotten almost 100km out of the tank when the light turned on.

Pretty close to a full tank, I mean I fill it up till the click, wait 5 seconds and fill it till the 2nd click.

I'm certain they'res something wrong with my car.

How many litres do you then fill up when it's 'empty'?

You need to measure by how many km's to litres poured as fuel indicator light may give false readings.. I think an ep3 tank is about 50L. Drive 100km and fill up and see how many litres it uses. On average use 10L per 100km

I just calculated it and yesterday I filled up about 44L, spending around $75 with Vpower being $1.70.
I'll let you know how far I get with this tank, this is with the fuel flush mixed in this tank.

But I know for certain they'res something wrong, I've logged my past fill ups, and for the last 5 full tanks I haven't been able to get over 330KMs till the light appears. I was expecting at least 400kms.
