Fuel Economy

[garvard]

Hi.

During last period I found that my '99 RX300 with 115K miles used too many fuel. The display shows 12-12,5 MPG on urban driving.

Who know: what could happen? And to increase?

Thanks for any advice.

- Try Cleaning the AirFlow Sensor - see MAF sensor cleaning instructions

- Check for siezed Brake Caliper?

- Fuel Pump losing power??

- Have Fuel system cleaned?? In UK we have stuff like REDEX but not sure if you guys have that in the US??

- Have diagnostics check to see if any oxygen sensors are out of kilter.
