| CWB. To EM. from Hs.{Lord Ernest Hives - Chair} X53 Hs{Lord Ernest Hives - Chair}4/LG14. 6. 26. PINKING AND DETONATION. X53/X93 Replying to your CWB1/GM9. 6. 26. We have found no disadvantages in using Benzol mixture. R.{Sir Henry Royce} frequently uses this fuel on cars he runs. We understand that pure Benzol is very difficult to obtain. The fuel which is most easily obtainable is National Benzol Mixture. We have found this quite satis- factory both on the 20 HP. and 40/50 HP. cars. We see no reason why customers should not use National Benzol Mixture. Our experience is that the detonation on either Phantom or 20 HP. is not sufficiently bad to justify our recommending a special fuel. Hs.{Lord Ernest Hives - Chair} | ||
