got several quart size tins of real lead that I've bee saving for my 56 Austin Healey 100-4. along with several quarts of non-detergent motor oil.

older motors made pre-lead gas era uses valve guide/valve stems not designed for unleaded fuels. will run real lead sparingly along with marvel mystery oil for top end lubricant.
