Because they're older, my in-laws have been in quarantine since early March and haven't driven their car at all. It's been sitting in the driveway in New Jersey (USA) the whole time, in mostly above-freezing and then warm and hot weather.
The car is a 2012 Subaru Forester and it's always been very reliable. Now it won't start, probably because the battery is dead. We could jump start the car, but if it does start and operate as normal, is there any other reason not to just drive the car for a while after that?
Some sources say to drain the gas and all fluids and replace them before driving, but that would be a lot more effort, obviously. Is it necessary to do so?
