All Oil Prices Not Created Equal
That explains a lot! Why don’t gas prices go down when the price of oil falls? Which oil price would you be referring to? West Texas Intermediate? Brent? 
Right now WTI trades about $20 less than Brent.
Asian demand – more tightly connected to Brent than WTI.
Why should we care? US refiners get a lot of their oil from overseas. You guessed it. More the price of Brent, than West Texas.
