If there is a way to track when my car actually filled up then the MPG might be accurate, but it always thinks I get 4-5 better MPG than I actually get as measured by the odometer andgallons filled

Hi Scott. It looks like you're still using Gen 1 adapter. Is that correct? I see several cars on your account. Which one are you referring to here? Did it just recently start seeming like the MPGs are off? 

Here's a FAQ about MPG calculations. And here's another about MPGs not matching the EPA.
