We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Dave Osborne
saying something like:

Thanks for that Andy. However, GC actually said that putting petrol in a
*kerosene* tank was stupid. I was wandering if this was because it would
be pointless (as there is no wax in kerosene) or dangerous (because the
boiler might explode)?

I was thinking of the danger aspect. It *should* mix well, but what if
it doesn't and a slug of petrol gets drawn into the fuel line? Also,
raising the volatility of a kerosene fuel in a domestic burner (or any
flame application for that matter) strikes me as foolhardy. Again, who
knows what ratio to add, it might take very little to cause a problem.

Lobbing a gallon of petrol into a diesel tank on a truck or other plant
is a different thing entirely and is a practice which has been carried
out for decades, quite safely.
