So how 'bout that Ecometer by Auto meter?

[Cosworth]

The meter actually underestimated the average mpg (meter read ~49.x mpg). However, I need to stick to one gas pump (at a gas station) to really see where the difference might come from.

Cosworth, nice numbers. Were you able to compare the ecometer's avg mpg to "an old fashioned" calculation at fill up? Just curious how close it was. TIA
