We're between $400-$600 per month for the daily drivers. I drive 40 miles round trip 5 days, my wife drives 70 miles round trip 5 days.
I tracked our fuel costs for 3 months earlier this year.
That amount doesn't include the 911. I might spend $100-$150 a month but that isn't consistantly so it doesn't count.
Besides, I don't buy any fuel for it for close to 5 months during winter so it all works out.
