There has been too many 'crisis'
73 it was a little difficult to buy fuel. Though my only motorsport of that period ran on normal pump petrol.Which at that time I bought by the 44 gallon drum on my fathers account.
There was also a couple of national strikes which did not help. again still buying on my fathers account.
Soon after that though it was cheaper at the retail sites so we gave up on petrol. Diesel however was still cheaper in bulk.
Late 70s was another crisis, at least here in Oz. Reputedly the oil came from somewhere not producing? to make Avgas.
At that period instead of using avagas I was using 16L of super grade petrol with 4l of toluene. Performance was ok but not quite the same,, and it stripped paint as well!
There has been too many crisis since then, mostly manufactured ones to increase the pump price.
Normal?? petrol was $1.75 a litre here a few weeks ago and is now under a $1. The barrel of oil is now near record low for this century.
