My mpg only goes up coasting in neutral. She is not a turbo, FYI.

I'm curious about my next fill up.

Thanks all!

...yes, your Fiat has a built-in MPG display, but notice that you have NO way of calibrating its values, which is the major reason people here keep metioning that you should consider getting a separate fuel economy guage, such as ScanGaugeII™ or UltraGauge™ or similar.

These devices (like your Scion) will jump to 99.9 mpg when you coast, but ONLY *IF* the Fiat computer goes into Deceleration Fuel Cut-Off (DFCO) mode...which it might NOT be doing.
