Lexus Gs 460 Mileage Issues

[Abraham]

Hi. I recently purchased a 2008 Lexus GS460 with 67000 Kms on the odometer. It was purchased from a dealer and the comprehensive vehicle inspection I arranged came up as very good condition.

The car drives great. I only have one concern. The total driving range I am getting from a fuel tank is 400km. Is that normal for this model? The car has last been serviced at Lexus at 60000kms. Does anyone who owns this model have any suggestions?

Just to add to that. I am getting around 16-17l/100km as per the car's mileage display. I mostly drive in outer suburbs. Normal driving style.

Doesnt seem that great. Im getting 10-13 in my GS430. I drive it with a heavy foot at times too. Ive driven both teh 460 and 430 and tbh there is not much difference in terms of power.

I get almost 550km per tank
