Same 1,000 miles a month, same car, each state's own prices. Delaware saves $98 a month.
Gas prices jumped in 2026 when the war with Iran disrupted oil shipping through the Strait of Hormuz. Home electricity is priced by utilities under state regulators and moves far more slowly, so the gap tends to widen when gas spikes. For a 27 mpg car to cost less per mile than charging at home in Delaware, gas would have to fall below $1.50 a gallon.
