If you needed lead in petrol to prevent pinking, how does unleaded work? Surely without the lead your engine would break. And we all know that's not true. You don't specifically need lead in your engine to prevent pinking, you need an anti-knock agent. Tetraethyl lead just happens to work as one. So do other things, many of which are much less harmful (but some of which are equally so), which have been developed and used since then. True, tetraethyl lead was used because it was cheap, and also because it didn't involve diluting fuel with something of a lower energy content such as ethanol. Why would oil companies add lead to petrol if they didn't need to? It would cost them to buy the lead and they would get no benefit from it.

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary.

INcreased levels of Benzine in unleaded is more harmful than the lead in leaded petrol. Benzine causes birth defects and all manner of horrid stuff. Yup and they say you should NEVER even sniff a can thats been used for unleaded fuel and you should always be "up wind" when filling up a vehicle with unleaded fuel. I'm sure I read somewhere that unleaded is better than leaded for the environment but not for humans....

I don't know the science and can't prove or disprove anything! ;D But... I used to run my '82 Civic on unleaded as it was supposed to run on 2 star or 3 star, and I figured it'd be safe enough. I then proceded to rack up thousands and thousands of miles - in five months. Until one exhaust valve lost a big chunk while I was overtaking a Transit on the A14! Still, new valve (and gaskets etc) and it was fine for another couple of years on LRP. Incidentally it had done 90k and the engine - combustion chambers, bores, piston tops, everything - looked brand new. Hondas rule! I'd suspect that was probably due to mechanical failure rather than leaded vs unleaded fuel. I'm pretty sure Japanese cars were designed to run on unleaded since at least the early 1970's if not earlier?

I'm dead then because I've drunk several litres of the stuff over the years sucking it up from the tank and washing parts in petrol with my bare hands.
