Driving in the time of COVID: Can gas go bad? Ray Magliozzi Dear Car Talk: Volvo I have a question that may be relevant now during the COVID pandemic, while a lot of people are driving less. How long does it take for gasoline to go “bad” in a car’s gas tank? I have a Kia Optima Hybrid and a Honda Fit. In normal times, I’d fill each one up every week or two, when it got half empty, so there’d always be some fresh gas in the tank. These days I’m only putting about 3,000 miles per year on each car. I drive each car at least once a week. If I fill up both cars, I can probably go two months (or more) before fill-ups! What’s the best way to manage gasoline usage so it doesn’t go bad? Thanks.
