IIRC in the US a lot of derv is used, but it should also be noted that derv and kero come from the same fraction of the fuel so more of one is less of the other.

Diesel is £1.049 near me. Even the cheap stations near work are £1.029. Not seen it for under a pound for some time now.

Try some of the supermarkets -Asda is usually a good bet - well- over the border in Warks it is

My local Shell now has the Petrol at 101.9 and the Derv at 100.9

The petrol was 91p at it's lowest and the Derv was 97p.

Now SWMBO has a company car I'm not so exposed to the high Diesel costs as we were sharing my car before but now I just need it for my work.
