REV XMELARQT Zinc Oil Additive – Zddp Enriched with Concentrated Oil

Will this product help with refreshing the seals in older cars (2009 Genesis, 2008 Jetta). Neither are high performance but looking to keep them goin

Is this pure zddp or is it diluted in another fluid?

How much can i add to one quart of oil?

Im rebuilding a 1993 ford f250 7.5l. putting a cam in with slightly better lift and duration. (stock cam reground). will this work for the break in?
