People with plug-in hybrids: What do you do about gasoline aging out? Do you add Sta-Bil to most tanks? Do you just stop charging it after a few months to burn through the tank? Just curious.
Gasoline doesn't go bad that fast in a modern sealed fuel system and engines with modern electronic control systems that have a lot of latitude to adjust in real time are really forgiving.
People are mostly projecting their experience with much more finicky lawn equipment to cars.
References? Because I'm seeing fairly recent discussions saying things like "gasoline starts to oxidize into varnish surprisingly quickly" and suggesting not letting gasoline sit for 6 months.
