Here is what is happening. The internal Prius MPG gauge will gave about 43.5 MPG last tank. My Ultraguage said that I was getting about the same 43.2. Yet when I filled up my calculations showed I only got 40.8 MPG.

The Prius also alerts me that my gas is low when the ultraguage still shows I have 3 gallons of gas left.

Has anyone experienced these issues before?
