The deep freeze got me a low of about 135 mpge on average. The lowest trip was in the low 120's mpge with temps in the single digits..
In march in the 40's my average is up to 150 mpge, which will increase range for sure. You can actually correlate range in miles to the mpge numbers you're getting.
