In my experience that's only true in TV adverts from my childhood. I've never had one unable to reach in real life.
(I only drive my normal passenger cars, not trucks.)
But I'm me not in the habit of doing that, because it doesn't usually matter for me.
I also don't know anything about any "arrow" signalling anything in my dashboard, maybe it's only on the US-made cars, I wouldn't know cause I generally know on which side I have to fuel my car.
We never, ever use "gasoline" or the Germanic "benzene" for this. Benzene is a specific chemical here, never ever a fuel.
