Was holding steady in the low-mid 40’s until Channing where we started getting headwinds and sleet moved in. Dropped to low 30’s around thenDefinitely should have put in more than that when making a big leap in cold weather....I guess now you know that too. - signed Cptn Obvious
I've found Nav's estimates are rock solid above about 45-50F, the further below that you get the more overshoot on optimistic side it gives. At least that was the case a year ago, I did not do enough cold driving long distance this winter to give a proper evaluation but the bit I did do suggested it has improved at least somewhat.
What was the outside temp?
