Lubricating your 3/8" spiral balances might not solve the problem. Since they are fairly old in balance-terms, you might need new replacement balances entirely. See our Series 400 spiral balance, I think this might be what you have. If you want to lubricate the spirals, you will need our charging tool, the 75-005. I like to use lithium grease.
