Discussions about lead and alcohol in fuel are nothing new.
This is from Hints and Tips for Motor Cyclists, a book published by The Motor Cycle in about 1932.
“ Fuels
A number of special fuels containing a percentage of tetra-ethyl lead are now obtainable. The object of tetra-ethyl lead is to prevent detonation, and the advantage is that it allows a high compression ratio to be used, with a resultant increased power output. For normal work an ethylised fuel is unnecessary, but it has the advantage of increasing flexibility. This increase is due solely to the absence of detonation, or, in other words, of knocking. The addition of benzole to petrol or the use of a fuel containing alcohol also has the same effect.
Benzole always contains a small percentage of water, so, where this fuel is used, either pure or mixed with petrol, it is advisable to clean out the carburetter periodically. This precaution is even more necessary when alcohol is used.”
On a different topic, it has this advice;
“Dogs have caused many accidents. Pass a lively dog rather cautiously, and if he evinces an inclination to charge, swing the arm up, as if to hurl an imaginary stone. This is far more efficacious than cursing him.” Maybe I should have known that on the two occasions a dog has leapt at my front wheel. Both times the dog survived (with a headache no doubt).
