Inflation as reflect by oil prices

For those of us who still use motor vehicle to get from one place to another the cost at the pump is an important factor.
The price of oil ended 2010 at $91.38 a barrel, rose to a 2011 closing high of $113.93 a barrel on 4/29/11.
Ultimately finished 2011 at $98.83 a barrel. 
This reflects an +8% price increase during the year.
