Fuel Prices with Regression Lines Starting in 2012.

Russ Steele

I have updated the fuel prices, shortened the data to 1 June 2010 and added a regression line to see the over all trends.

Note the jump in gas prices in Sept 2012 that never went a way. I have been unable to find a good reason for the jump. While gas prices continue to decline, the disparity between CA and US continues.  While gas prices are declining, diesel prices are essentially flat.  Reader comment on the gas price disparity are most welcome.

You comments are most welcome. Please post your comments here.

    Russ,

    Since the point of the exercise is to look at the premium California pays, would it make more sense to plot the difference between CA and CONUS prices to see if the spread increases much after AB32 kicks in this Jan.

    Sean,

    Excellent idea. I wanted to improve the presentation for 2012. I will work on it over the holiday.
