Chemical Components of a DI Additive package II

[MolaKule]

It has been awhile since these were discussed. Since interest in growing in the these components, we'll have a series on the chemical components of a DI additive package for Lubricants.

These may require some BITOG and internet searching for the answers:

This series is NOT open to Tribologists or anyone in the chemistry disciplines.

Q2: A Borate ppm number showing up in a VOA or UOA is usually indicative of a functional --------------- type chemistry component.

See DI functional type chemistry categories below:

(DI is the industry term for the additive package mixture that contains detergents, dispersants, anti-wear, rust inhibitors, metal deactivators, friction reducers, anti-oxidants, cleaners, emulsifiers, anti-foamants, etc).

Just for information, DI stands for dispersant-inhibitor.

Please read the paragraph in parentheses in the first post.

Do you have an answer to Question 2?

This isn't about oils used in direct injected engines

What relation does this have wrt Question 2?

It was a simple comment, Chief. Delete it if it rubs you wrong.

Just trying to figure out what relation it has to Question 2. If you do not intend to answer the question, then your comments will be treated as Off-Topic and deleted.

Q2: A Borate ppm number showing up in a VOA or UOA is usually indicative of a functional --------------- type chemistry component.

A: This would be indicative of an Ashless, Friction Reducer, Anti-wear, and Anti-scuff agent.

Sometimes it is phosphorilated, which means it is combined with another anti-wear phosphor-type component. This phosphor component raises the phosphorus levels somewhat.

It is particularly useful as a cold temp Anti-wear and Anti-scuff agent on cold startups., before the MoDTC (moly component) and the ZDDP have had time to activate.

While I didn't answer the questions Chevron was an early user of Boron/ Borate additives in lots of their oils and gear lubes.

Very true, in fact they hold patents on the technology, specifically, the potassium Borate esters used in, as you say, gear lubes.
