Oil prices continue to be at high levels that do not reflect reality in the markets.
The main cause of this is a combination of speculators and continued political issues particularly in Iran. The medium term picture sees very little respite in prices unless the Iranian situation becomes less volitile.
In addition, we see continued strength in the US dollar with some commentators suggesting further strength to about $1.26 / €1.
Furthermore, demand for petrol always increases in summer and demad for diesl falls - thus refinery premiums for the 2 products have changed and the cost of refining petrol from the refineries has increased and diesle decreased. This happens every Spring and Autumn and is why we've seen diesel go from almost on par with petrol to now being 8c-10c lower.
In the short term, we will see about 2c - 3 c come off the recent highs at the pumps based on the drop back from $125 to $118 over the past couple fo weeks, but that's about as positive a news I can give at this time.
But don't forget, planning the journeys, taking it easy on the motorways and open roads (under 100km/hr), less use of braking and watching the road ahead and allowing the car ease to a halt will give you up to 30% extra mileage. - It may be boring driving, but its saves money.
