Lead Substitute

[adam_knox]

Hey gang, out of curiousity, what happens if we neglect to add lead additive to the tanks? The guy at the store said my car probably doesn't need it because the pistons are already hard In any case, I add it, but I'm just curious in case I do find myself without a bottle in the trunk! Hate to destroy the engine on one fill-up!

Not necessary to add lead to these flat-head engine. They were built originally with hardened seats so the lead additive is not needed. I doubt if it hurts in the short run. Don't know about buildup in the long run.

It's a waste of your money. You don't need to add the lead additive at all.
