Even though gas prices ramped up in the past week, they're still less than half of what they were last summer.
If your vehicle gets 20 mpg and you drive 18,000 miles per year, your annual cost for gas is $3,600 at $4 per gallon -- but it's only $1,656 at the current Minnesota average price of $1.84 per gallon.
That's a savings of nearly $2,000 per year, or an extra $160 per month.
