I've never had a problem with any of my adapters until I got this new car. It's a Cadillac ATS-V, with a twin turbo 3.6 liter V6.
Automatic reports 48 MPG on the low side, 55MPG on the high and usually returns 53MPG or so for my 50 mile commute to work each day.

Anything that I can do?

Hi Jeremy - please take a look at this FAQ. Meanwhile, I'm exporting your post to our helpdesk system so Tech Support can help you directly. They may need to make a manual adjustment. Please keep your eye out for an email from support@automatic.com

Hi Amy,

While not explicitly stating it, the FAQ refers to situations where the observed fuel efficiency is much lower than the anticipated efficiency.

In Jeremy's instance, the rated efficiency is 17/23 mpg (city/hwy). Automatic's reporting 2 to 3 times that value is surprising .....

Yes, that's why he needs to be helped by Tech Support directly. There's something specific to his car that is going on here and we might need to / be able to make a manual adjustment for it. I don't know that for sure, though. Tech Support will look into and see what's going on.
