That lawnmower oil I mention is rated SJ which is the higher zinc content. After SJ zinc was being reduced, so there is an example of a manufacturer wanting the zinc.
Thus, given how expensive those motors are leaning toward original specifications is meritorious.
As mentioned, Risolone sells a zinc additive for oils rated higher than SJ. At present those diesel oils have higher zinc, but the lighter grades sometimes are hard to find in stock.
