It ends up being bank dependant a bit. (USA here)

If I use either my cashapp or chime card I had better have the full $100-200 on there or it will fail the authorisation.

On the other hand my main bank is a local bank and they treat all gas station preauth's as a $1 charge. So I can have say $30 in the account and still get $25 in gas whereas many other cards/banks would just decline.
