Pure City Driving MPG - Toyota Yaris Forums

Using a Scan Gauge to monitor the fuel economy during driving can be very revealing. Watching the instant MPG read out you will see something like 4-8 mpg in first gear (moderate acceleration). Shift to second and it goes up to around 12, third around 18 MPG, fourth gear 23 MPG, and fifth would be around 26.

The important take away from that is that fifth gear is where you want to be. The more time you spend in the low gears the more fuel you burn with out actually moving on down the road.

Of course when you are at traffic lights your efficiency goes to zero.

I mainly monitor my average and pay little attention to the instant reading as pulse and glide works better than a light foot. Get up to speed as quick as you can, traffic permitting. One half throttle does not seem to be too much, and shifting too early is wasted effort as well. Best to shift around 3k RPM so as to operate the engine in the most efficient band, then once you can get to the highest gear you can then back off and drive with a light foot at low rpm.
