Not necessarily be the O2 sensors. Fuel related issues can throw out DTC's ( Diognastic Trouble Codes) which may indicate lean/rich fuel mixture. 

I would throw in the fuel tank top quality Fuel Systsem Cleaner/Conditioner prior a fill up with Premium 98 Octane Fuel ( Liqui Moly Fuel System Cleaner Conditioner ). Autobarn, Supercheap Repco sell this stuff. See how it goes B4 starting to replace O2 sensors at that ridiculus cost and potentially getting no positive outcome.

Fuel pump/Filter is another thing which I would look into. 

You need a scan tool or someone with a scan tool to read and erase the code prior addind the cleaner and re-checking it after.

Thank you, for your advice. Do you have an idea what is an ideal fuel consumption for this car in the city? 

Hi everyone,

I noticed that my gas consumption is going up (14.7L/100) so I took my car to a mechanic. It is 2005 ES300.

I knew purchasing this car 2 years that an O2 sensor is bad. It showed on the diagnostic device. Now the mechanic recommended changing all O2 sensors. He said there are 3 - 4 of them. Roughly he said it will cost 900+. 

Anyone had similar experience/advice to give me?

I live in Ryde, Sydney.

Thanks 

Oh thank you. That's very helpful and assuring. 

Thank you for the advice. Do you know a good independent lexus/Toyota mechanic who can do the job in Sydney? 

Hi everyone,

I just bought a 2005 Lexus ES 300 and I am in doubt that the fuel consumption is high. 16.3 L/100 Km. 

During the pre-purchase inspection I was told it may need an O2 Sensor. Is that the reason or do you think the consumption is normal?

Thanks,
