I wouldn't carry a gas can around in my car unless it was metal. Those two both look good to me.

STA-BIL works fine with car engines; just a week ago I pumped out the gas tank on my generator, poured all the old gas into the car and refilled with fresh. Car runs fine. Don't use STA-BIL from a bottle that's been open longer than two years, and use the gas within twelve months.
