Maybe if the price difference does indeed lead to more oil used.
Lower prices might be good for countries like Germany to stockpile for Winter (so oil & gas they'd already use anyways) while hurting producers that rely on it being a high price to be profitable.
Less profitable may lead to less investment in oil development while wind, solar, and other means become more prevalent.
And a terrible effect on the environment. But that's not what anybody is worried about right now.
