How long will gas stay fresh in my tank before it harms the engine?

Asked by GuruL2WK Aug 01, 2020 at 08:03 AM about the 2015 Hyundai Sonata

Question type: Maintenance & Repair

With few places to drive to beyond the grocery, gas gets to stay in the tank
much longer than usual. If necessary, what is the best product to use that
refreshes the 'stale' gas? Will filling a half-full tank solve a stale gas problem in
my tank?
