Don’t own a PHEV (honestly a terrible idea for where I live) but I have worked in fuel for years:
There are additives that make fuel stable for up to 2 years. Technology Connextras has a video where he starts a mower or something after a full winter of it being unused and it just starts.
Also, PHEVs will periodically force the gas engine on for that very reason I’m pretty sure
