Truck fuel (6)

Ross

I believe the answer is:

diesel

'truck fuel' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for diesel that I've seen before include "Vehicle fuel" , "Engine fuel" , "Type of engine" , "Type of fuel oil" , "Fuel for heavy vehicles like lorries" .)

I've seen this clue in the King Feature Syndicate, The Star Tribune, the Penny Press and the Newsday.
