The price of oil increased from $3.00 barrel at the outbreak of the war in Oct. 73 to $12.00 a barrel on Jan 1, 1974. The problem was that once the embargo was over OPEC did not restore their pre-embargo production rates thus keeping the price high and contributing a great deal to inflation.
It was not until the 1980's that the Saudi's figured out that if they were going to have investments in the US that it would be in their best interest to increase production and restore the American economy.
Check out the following thread on this topic from a while back, particularly Post #69. We had a very interesting discussion about the subject of oil prices, currency valuation, etc.:
1973 U.S. Threat to Seize Oilfields
I'd be interested in getting your take on this, but my suspicion has always been that the 1973 "embargo" was nothing more than a deliberate attempt by the U.S. government to cover up a deliberate effort to devalue the U.S. dollar.
