| Rm. {William Robotham - Chief Engineer} X1282 Hd {Mr Hayward / Mr Huddy} /SB {Mr Bull/Mr Bannister} 21/HR.3.11.36. re EFFECT OF ETHYL PETROL ON SPARKING PLUGS. --------------------- We attach hereto copy of H18/RH. {R. Hollingworth} 30.10.36., on the above subject. Although you have assured us on several occasions in the past that Ethyl has no effect on sparking plugs, we believe you are now satisfied that the effect does exist, particularly on cars running only short distances. We shall be glad to know if you have any information later than that detailed in Hs {Lord Ernest Hives - Chair} /Wst5/MJ.7.9.36., or better still, perhaps you would write direct to H. {Arthur M. Hanbury - Head Complaints} giving us a copy. Hd {Mr Hayward / Mr Huddy} /SB {Mr Bull/Mr Bannister} | ||
