The simplistic answer.
Gasoline is a commodity
Crude Oil is a commodity
Some types of crude oil are used to make gasoline so they are correlated, but it's not a direct correlation.
Further when people talk about oil they are quoting the spot price, usually WTI or Brent, when is different than the price a consumer pays at the pump.
For instance here is the equivalent WTI of Gasoline.

Then there is the whole economics of gas stations of which I'm not an expert... if I was to take a WAG, I would guess that your local station buys it's gas at some sort of whole sale price fills it's tank then charges you a mark up. They bought the whole tank at "$110" so they don't really change their prices till they sell the whole tank.
Conversely as they see the price of whole sale gas climbing, they mark up what's left in their tank so they aren't fronting as much money when they go to refill it...
Again could be totally wrong on that's just my thought, I imagine it extrapolates even to Exxon and other super majors.
