You seem to be changing that subject to correspond with you rant about lead .
If you like merry-go-rounds, keep riding it but this is where I get off this one with you.

BTW, the whole world is not like AU. ...neither is it all like the US .
AU is largely dependent on foreign fuel so maybe AU feels it does not need to increase ethanol production.

Interesting, I hadn't heard the theory that it was the availability or cost of ethyl alcohol that was the reason for using lead, but it sounds plausible.

There was an interesting radio program on the history of lead in petrol by Tim Harford a few years ago. A short accompanying article is still online here:

Why did we use leaded petrol for so long?
Why did the petrol companies push tetraethyl lead instead of ethyl alcohol? Researchers who have studied the decision remain puzzled. Cynics might point out that any old farmer could distil ethyl alcohol from grain. It couldn't be patented, or its distribution profitably controlled. Tetraethyl lead could.
Thomas Midgley was also involved in the invention of CFC....and was killed by one of his last inventions #-o
And what of the scientist who first put lead in petrol?

In middle age, afflicted by polio, Midgley applied his inventor's mind to lifting his weakened body out of bed. He devised an ingenious system of pulleys and strings. They tangled around his neck, and killed him.
There's also an interesting piece about possible links between crime trends and lead exposure:

Did removing lead from petrol spark a decline in crime?

It's all a bit academic as it seems only Algeria still uses the stuff, but interesting from a historical viewpoint.

No rant, I said it was not good and neither is lead free, all I was saying lead fuel was not as bad as some made out and there are other aspects to consider. Aus is increasing ethanol production, but we need to grow food not fuel, ethanol is not the answer.

Ethanol seems to be hell for small engine fuel lines and carburetors.

We need to get away from petrol altogether eventually, not sure what alternative we have, but know it is not electricity, especially in counties like America and Australia where distances are vast.

Well, I ridden electric motorcycles and how do I put this....... I'd rather eat glass :D
With NOBODY hearing you approach (especially folks on bicycles and thus swerve all over the road) it is an accident waiting to happen. Note that I ALSO ride bicycles....





I'll stick with my gasoline engines thanks you!

I have an antique car with a 283 cubic inch small block Chev engine in it. I have to add an additive to the gas to help reduce any valve seat recession. It doesn't contain lead.

They also used lead in the old oil paints, plumbing and other things. Getting lead in the bloodstream can be very bad for your health, especially if it accumulates in the bones.

Yeah. engines were designed and tuned to run on leaded fuel,
So, an additive was of course needed to use unleaded fuel . :)

I used to use such an additive when leaded fuel finished, think it was potassium.

Sim-U-Lead - contains sodium. Much less poisonous than lead

I drive a diesel so these things are foreign to me....

Latest EPA studies have determined ethanol is far from being an environmentally friendly fuel, so I'm not sure what "needed quantities" would accomplish.
