Hallam - Head Repairs}22.3.32 re: Speedoil Anti-Carbon Upperlubrication oil n°. 192. ---------------- We have had an enquiry from one of our customers owner of a Phantom I chassis whether the above oil can be recommended. For your information we attach a prospectus from the Manufacturers also a copy of a report from the French "Ministère de l'Air". Apparently this product is put into the petrol tank and is mixed with the petrol, we are wondering whether it can have an effect on the plugs or effects the engine oil in any way. We shall be glad to have your opinion. The Manufacturers make big claims as to its properties re lubricating the upper part of an engine. Hm{Capt. W. Hallam - Head Repairs}/Va. | ||
