Back in the OPEC oil embargo of 1073 it was difficult to get gasoline.
Gas stations often had empty tanks and gas purchases were rationed in various ways. Sometimes the amount allowed was limited and most people could only purchase on odd-even days or by the odd or even number on your license plate.
Even though fuel was in short supply everywhere in the US there were photos of loaded tankers anchored offshore.
There were so many loaded tankers sitting idle that news outlets reported there were few empty tankers available.
The tankers were being used for storage offshore as they waited for prices to go up before they were cleared to unload.
Yeah, 1073 was a very bad year for gasoline. Thankfully, most horse power had four legs.
