The oil market is now down because most people are taking profits after seeing a sharp increase last week.
The production of gasoline in the U.S. is quite limited compared against the same period last year. And the refinery bottleneck situation is still a problem that drives the market.
Last week, there was an attack by terrorists in Saudi Arabia and that's why the market jumped, but the Saudi authorities were successful in foiling the attack so this calmed the market a bit, prompting traders to have a reason to sell.
