Yes, and all knives should be sold with corks on the ends.

A spigot that denotes diesel and sends a sensor deeper into its tank
would be ideal as most new diesel owners insist on overfilling their
tanks until the penny drops.

A diesel works on pre-ignition and relies on the fact that the fuel is
not of a high flashpoint. This allows a pressure of 25 to 1 to be
utilised and is the reason for their efficiency.


Efficiency? A mute word here. A diesel returns higher mileage because a
litre of diesel has a higher CV than petrol, no other reason.



No, not so.

Try reading a few engineering texts on Otto cycle theoretical
efficiencies etc.

Higher compression ratios and higher gas pressures equate to higher
efficiency,
