Comment[edit]

I dispute the factual accuracy of this article and it also does not present a world view.

First Lead Replacement Petrol by definition does NOT contain tetra ethyl lead. That is the point of it.

Is it banned worldwide?

TEL was added as an anti knock agent, protecting valve seats was a side effect.

There is no lead in exhaust gases, there are lead compounds. Malcolma (talk) 18:27, 27 March 2009 (UTC)


You are right, the article is wrong,. I will change it

the main point[edit]

TEL was used as an antiknock agent and that's all. No valve seats protection as the primary purpose.

Valve seat p[rotection was a useful by-product of TEL, according to Millers Oils it allowed the practice of machining valve seats direct in the cylinder head. —Preceding unsigned comment added by The Yowser (talkcontribs) 11:32, 8 May 2009 (UTC)
