Why is diesel called derv? what does it mean?

Reason?: all the garages i've seen without exception over last few days that have run out of diesel fuel, the notice says 'no derv'.

A tax thing. "DERV" is what C&E call diesel fuel with duty paid for road use.

Same sort of thing with AVTUR ("aviation turbine fuel").

A realitive who spend his working life in the oil and LNG industry told me this.

One of the big companies who he worked for introduced the fuel and termed it DERV, meaning Diesel Engineered for Road Vehicles

Apparently they tried to claim that DERV was their product name that other competitors had stolen. However the courts threw this out because they had not taken steps to protect it in the early days.
