Never drink the stuff myself

Production has caught up with demand possibly?

Has anyone else noticed how the differential between diesel and petrol has gone down ?
Now diesel is only 3p/litre more expensive than petrol....down from over 14p/litre difference !

Also a lot of people are realising now that diesel cars have stupid premiums that will take many years to recover out of fuel costs.

Fine Particles (PM10)
Particulate matter is a mixture of organic and inorganic substances. PM10 is the name given to those particles that have a diameter of 10 micrometers (µm) or less (one-seventh the width of a human hair). These particles can penetrate deep into the lungs and can cause serious damage to those at risk. Emissions of PM10's have declined over the last two decades.

Whilst some PM10 particles come from natural sources, such as dust storms or volcanoes, most are from man-made sources. 25% are emitted by road transport and **33% by industrial, commercial and residential combustion.*** When these primary PM10 particles are emitted into the atmosphere they can react with other substances such as Sulphur dioxide and Nitrogen oxides to form secondary particulates.

District Councils measure PM10 concentrations using electronic Continuous Monitors. These machines accurately measure real-time concentrations of the pollutant. In urban areas, typical mean values are between 10-40 ug/m3.

In Cambridge City, East Cambridgeshire, Huntingdonshire and South Cambridgeshire a recent Review and Assessment report found that air quality objectives for PM10 were likely to be met by the due date (2005). It however also found that in Fenland the objectives may not be met. This is because emissions in Wisbech are still too high. An Air Quality Management Area is currently designated in this town and the District Council is working with the ***industrial operator*** to reduce PM10 emissions.

Diesel for "non motoring uses" is cheaper anyway....it's red !
HMRC reckons that some 40-60% of "red" diesel is used on the road ! (59p/litre).

And perhaps more drivers are becoming concerned about the higher levels of PM10 pollutants emitted by diseasel engines.

The "Euro V" emissions requirements are likly to see pretty much all new diesel cars fitted with particulate filters. I expect they'll all do a bit less mileage to the gallon though, so more CO2 instead.
