[Healeys] Dieseling problem

[Ph.J.Aeckerlin]

Thanks to the eleven listers who came up with answers and/or suggestions 
to my problem with a dieseling engine. Generally speaking the low octane 
fuel seems to be the culprit. Unfortunately one can only buy two grades 
in this country: the 'normal' grade which is 95 octane and the 'super' 
grade which is 98 octane.
Also very unfortunate is the fact that I have to pay seven dollars 
ninety three (Yes: $ 7.93!)  for every US Gallon of this 98 octane fuel. 
And if you would know what the restoration of my BJ8 did cost.....
Why has no-one invented a car engine running on tap water yet?
