Due to the community quarantine our cars seldom get used. What is the real deal when it comes to fuel expiration in our local conditions? I have 2 months old gasoline and 3-4 months old diesel in our cars. It has been my practice to fill the tanks every visit to the pump to minimize water contamination from too much humid air in the tank. But now I'm starting to get worried the fuel system might get damaged from expiring fuel.

Can anyone shed more light on this?
