CRZ (Insight?) MPG gauge accuracy?
 

I've noticed that mine seems to lie once I get over roughly 45 MPG. Anyone else notice this on your car? Today I was showing 49.8/avg and wanted to check it for accuracy; Fully showed 47.88. It would have been neat to have a new best tank. 😟

I find my insight gauge to be off by exactly 2 mpg.
Well, ok, 1.99 mpg.

This was calculated from 40k miles of fill ups recording odo mileage, fuel in, and the FCD number.
