I don't know anyone that bothers either here or in the US.

I use Millers Octane Booster with lead substitute, bung a dash in every refill type deal.

Not saying it helps or even does a damn thing, but a spot of faith healing never hurt anyone

Never bothered with it on anything I've ever run. Never had any problems either.

Old engines should have what they call "lead memory" if they were ran on the old 4star. If they have been rebuilt they would have had valve seats redone.

You would need to know your head set up b4 using any form of additive.
