I should have corrected my statement: I know of the lead/unleaded problems.
I do not believe that kero is a substitute. I was looking for an answer like
it makes it burn cooler etc. I am well aware of the valve recession problem.
Is this possibly related to the problem when they switched from 3 grades to
2 grades of gasoline in WW2? There were reports of some engines not being
able to take the higher (80 as I recall) octane gasoline.
