Simple-minded people used to say 'we paid to put the lead in and now we're paying to get the lead out'. The fact was that higher octane fuel was required for higher compression engines and the cheapest way to increase the octane of gasoline was to add tetra-ethyl lead to it. When lead was outlawed it became necessary to increase the octane rating of gasoline without using lead. This was a more expensive process. I remember when we were still flying aircraft with recip engines. Military was using 115 octane gas (115/145). That gas had so much lead in it that our fingers would end up with a layer of white residue from all the lead whenever we came in contact with it. Some of the smaller engines ended up with lead fouled spark plugs. Looked like someone had soldered the points together.

We had to add TCP (Tom Cat Pee) to those little engines' fuel to prevent lead fouling. All because of low bids for gasoline supplies that met govt specs.

Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
