Unless you pulse and glide or go rather fast all the time, you won't average that kind of efficiency.

Yes, the overall, well-to-wheels efficiency for a gasoline-powered automobile has been calculated at 15% overall thermal efficiency.
For the sake of simplicity, I'm using a constant-velocity, cruise-speed scenario for highway-only driving.
Short of having specific manufacturer-supplied data, estimating/ guestimating , is all we can do.
And that's the premise of this thread.
