I predict a surge in cars that won't start when the stay-at-home orders are lifted.
The whole "gas goes bad in X months" this is basically an urban legend at this point but it's continuously propped up because most white collar people's experience with gas older than a few months is trying to pull start some piece of garden power equipment that has the cheapest carburetor known to man on it, a compression ratio in the ballpark of "maybe" and barely runs on a good day and then can't start once you make the gas even mildly less volatile. Old carburetor vehicles could certainly gum up but they'll do that with premium too.
If you don't daily drive a moped, motorcycle or bicycle with one of those engine kits you'll be fine.

/disclaimer: any time i raise the hood on a car the repair cost is automatically 2x the cost had i not raised the hood. I am not a car guy not matter how much i wish i was.
Why would too little be an issue? Won't it still be better than not using it at all?

I'm sure they're still being used to go to the grocery store and possibly trips to the pharmacists, laundromat, or pick up take out.
I assume because if you don't add enough you don't get the benefits and it's just a waste of money.
If you don't use your car, or all you do is just going for groceries, Old advice is to drive 10km once a week. Go to a road or motorway. Let the engine work.
Plenty of ethanol advocates have successfully stored ethanol fuel (no gasoline) for years without issues. It can have problems, but they are over pushed by oil shrills.
