| 1282 To Rm. {William Robotham - Chief Engineer} from Sg. {Arthur F. Sidgreaves - MD} Copy to Hs. {Lord Ernest Hives - Chair} Sg {Arthur F. Sidgreaves - MD} 10/E23.11.36 You have doubtless heard from your man who worked on my car at Lillie Hall last week that the mysterious trouble I was experiencing was entirely due to plugs. I am not so seriously concerned with the trouble on my car as with the fact that I understand it is due to the use of Ethyl petrol and, as we are recommending the use of this on all our cars, it looks as if we were piling up trouble for ourselves. I suggest that a Depot Instruction Sheet should be sent out describing the symptoms and the remedy as, if owners experience the trouble I had, I can see Depots spending many hours trying to trace it, especially as it is so elusive, i.e. sometimes present and sometimes not.
