CD2 lead Substitude is on clearance at wally world for $3 a pop. any usefullness in a matro? I grabbed a few for use in my old boat and mower engines and pop's motorhome (they were out when leaded fuel was around)

any use in the metro? would it help with valves or hardening anything? Do nothing? or even cause harm?

Sir, yes sir!

I know that lead will kill a catalytic converter, but I'm not sure about a lead substitute. It should say on the bottle.

Older valve seats would get eaten away if they were run on unleaded gas. I guess newer ones COULD benefit from it... but the only problems I hear about regarding valves in these cars is burning.

In short... :whistle I dunno.

I read your post and when I got to this, I just laughed for no apparent reason.

Does it say catalytic safe or anything on it? If it was designed as a lead replacement, that would suggest it was meant to run in an engine that needs lead, which wouldn't have a cat. I'd say even the replacement stuff would kill a cat (lol) if you ran it as its using something else that coats surfaces as it burns, which is what ruins the cat. With the hardened modern valve seats I wouldn't think there'd be any advantage, these cars are designed to fun without lead, and adding it I'd think would be counter productive.

Interesting fact: most high octane racing fuel is leaded.

Lead is necessary to allow octane to be increased much over 100 or so, airplane fuel is also leaded, and its 110 octane. Its listed as 110LL (low lead) Both aircraft and drag cars don't have cats :)
