It is simply not true that no anti-knock alternative to lead tetra-ethyl exists.
There are many motorists in New Zealand who use older cars that require
leaded petrol or something that substitutes for it, and the additive is easily
available over the counter. Off the top of my head I don't remember the
name of it, and my old Ford Transit van to which I fitted a Zodiac 3L motor is
500 km north in Christchurch, and its there I have some of the additive; and
I've seem it in auto shops recently. It is some kind of phosphate, is all I
remember right now.
When I see it again, I'll advise - maybe I'll ask at the local garage a mile
away - they most likely stock it still.
