Are you claiming that 'small player'/boutique blenders (like Red Line) which have high 'dimer'/di-nuke type moly levels are also guilty of the above omission/oversight??
Or was this ONLY directed at car
owners dumping untold amounts of (non-LM) moly
additives into their sumps?
No, when the folks here talk about additives, they are talking about ones not included in an engine oil by the oil mixer or oil company. Oil mixers like Redline do test their products to some extent, BUT most of the so called Snake Oil Mixers do not.
I do use Ceratec with Shell Ultra and LM Synthoil High Tech, but I'm sure LM test their additives with common major brand oils.
Most Redline oils seem to be aimed at Race engines or thin oil applications, so they have a lot of Moly and less detergents. So they are not designed for long OCI's.
