Hmm... all the reading I have done would suggest that the price of crude oil is rising again - its been on a rollercoaster from the highs of around $150/barrel last year to a low of $30/ barrel about 5 months ago.
Since then it has increased to around $60-$65/ barrel, and is projected to go higher, based upon OPEC keeping to their existing output targets, and various investors and speculators essentially betting that the global economy has reached the bottom and is going to come roaring back.
The consequence of all this is petrol prices such as unleaded gradually sneaking back up to around �1 / litre from lows earlier this year of �0.88/Litre just a few months ago.
