NOTE:
A note on mixing oils and additives: Chemicals tend to react with one another. Some
interactions are of no consequence, others are beneficial, while still others may cause
some degradation in the service capability. It is not recommended to mix products which
are intended for different service applications; for instance, a transmission and a gear oil.
Since the original lubricant manufacturer puts a lot of time and expense into ensuring that
their oil will meet the required qualifications, it is not a good idea to introduce additional
chemicals which may upset the delicate and critical balance originally obtained.
This means that supplemental additives are not needed and normally are not desired in
a fully compounded and qualified lubricant.
