Fuel Gauge

[Eddie Kelly]

Just purchased an immaculate yaris 1.0 02 plate with 57000 miles on the clock and immediately gave her a service, new oil plugs and filters etc. Love the car but hate the fuel gauge. I started my journey to work last night on a new bar, drove 30 miles motorway, 15 each way. Have just got in the car and already down a bar. I bought this car for the so called fuel efficiency but feel it is no better than my old peugeot 1200. Is there a way of telling what MPG i am getting without having to fill the tank? How much do I have on the last flashing bar. Frustrated

The fuel gauge on the Yaris is non-linear (see my thread below for more info). With the last bar flashing slowly you would have about 2 gallons left and at the fast flash about 1.6 gallons left.

For knowing your economy, many people use the ScanGauge II or the Ecometer (both of which plug into the OBD port) to see instantaneous fuel economy.

Thanks Scott. Is there a cheaper less scientific way of measuring without filling the tank. Checked out that piece of equipment (gauge reader thingy) and they appear to be quite pricey.

Did you actually fill the tank yourself, or take delivery of it with a "full" tank?

Not really. With the large span between bars it would be difficult to use them for any kind of analysis. The aftermarket economy gauges are the best way to go, and if you keep your eyes open on ebay, used ones can often be found for far less than new.

If you have an Android device, you can purchase the app called Torque (free, or $5) and a bluetooth OBDII adapter ($15~25).
