Gas locally is around $2.15/gallon. I anticipate it down to about $1.95 in the near future. West Texas Intermediate crude and Brent crude are pretty much the 2 hallmark prices. They have been down about $10 a barrel in the past week or so.
A barrel has 42 US Gallons. Thats 3.83 Liters I think. Oil prices change a dollars a barrel generally results in about 2 cents a gallon change.
http://www.oil-price.net/ is a good, easy website to follow the WTI and Brent prices.
March, Friday 20 2015 - 11:21:16 WTI is $43.96 -0.70 today, Brent Crude is $54.43, -$1.48 today
Off on a side track here. If BHO gets his Iran deal and sanctions lifted immediately (like he wants) over the next few months Iran will be back in the world market. They have lots of oil and need lots income. One of 2 things will happen. Oil will be fall back to $25 a barrel (gasoline here at $1.49) or Iran will threaten to do that and get enough dominance in the market to push it back to $80/bbl with gas at $2.99.
Get in, sit down, shut up and hang on. The roller coaster is getting read to launch.
