It's nothing like the automotive oil. With higher ZDDP, calcium and a generally robust additive package. It's also very shear resistant and has a high HTHS.
Thanks to BITOG data I think we finding the single most common
misunderstanding about motor oil is that higher zinc levels provide
greater wear protection. fact is more zinc provides longer wear protection...
but thats a moot point given the short oil change intervals owners
Zinc is used/sacrificed in very small quantities at time, so the total
amount present in your oil does not change how much wear protection
the oil provides, as long as you don’t run out of zinc. “Lab Testing”
and “Wear Testing” analysis proves/confirms that more zinc provides
LONGER wear protection, NOT MORE wear protection.
1. Well known and respected Engineer and Tech Author David Vizard,
whose own test data, largely based on real world engine dyno testing,
has concluded that more zinc in motor oil can be damaging, more zinc
does NOT provide todays best wear protection, and that using zinc as
the primary anti-wear component, is outdated technology.
2. The GM Oil Report titled, Oil Myths from GM Techlink, concluded
that high levels of zinc are damaging and that more zinc does NOT
provide more wear protection.
3. A motor oil research article written by Ed Hackett titled, More
than you ever wanted to know about Motor Oil, concluded that more
zinc does NOT provide more wear protection, it only provides longer
4. This from the Brad Penn Oil Company: There is such a thing as too
much ZDDP. ZDDP is surface aggressive, and too much can be a
detriment. ZDDP fights for the surface, blocking other additive
performance. Acids generated due to excessive ZDDP contact will
tie-up detergents thus encouraging corrosive wear. ZDDP
effectiveness plateaus, more does NOT translate into more protection.
Only so much is utilized. We dont need to saturate our oil with ZDDP.
