Jay Davidson sent me this information about another product that has a good amount of ZDDP zinc in it. Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment. Here is what he had to say about it.

"As you know most modern oils do not contain ZINC which old cars need.. RISLONE has a product that is loaded with zinc.

I bought a bottle and put it in. Ever since I owned the car, I have had a small oil leak. This product sealed 100% of the leak. It is at all auto parts stores. Make sure you buy the correct product."

Here is their website regarding this product, what it contains and why you should use it in these old classic cars of ours.
