>>I feel that some information is required here. US domestic gasoline market stopped to be independent long time ago, about 70s when construction of new refineries was effectively banned. Since then, USA imports increasing amount of gasoline from foreign countries, so currency fluctuations (e.g. between USD and Euro) affect gas price on daily basis.
>>The major thing that is 'not clear' to me is the following. There are too many people with rather preliminary knowledge of oil or any other commodity markets, but with extremely firm knowledge about collusion and gauging. Imho, it says more about personal attitudes or social views than about actual situation in particular industry.

The oil lobby has too much money and can have the best propaganda money can buy, and they can cherrypick the hardest to prove points as their reasons for doing what they are doing, but they cannot explain away the record profits they had in the last two years.

Graphed if possible.

You can read quarterly or annual report of any refinery company. It is available on most financial sites (Yahoo.Finance is one place) and get full set of different prices. Obviously, it's impossible for me to have all these numbers on hands. One generic number: $20 is considered as break-even number for US domestic oil producers; certainly it's much lower in Saudi Arabia.
