Sodium and Moly+Boron question...

[wemay]

Notice I didnt say versus.

The question is, why arent there any oils that use both? It seems, or is, that they either choose one or the other as the prime additive exclusively.

Chevron delo 400 uses it. uses about 100ppm of moly and about 500ppm of boron. All the other diesel oils hardly have much of either one.

There are several PCMO's that have sodium, boron, and moly in their additive packages.

Valvoline, GTX, and Supertech come to mind.

Also Boron and moly are friction modifiers.
Sodium is a detergent/dispersant.

Two varying functions for the three additives you have mentioned.

Boron is used in more than one class of additives, so without knowing the inside scoop, we can't know what's it's used for in a particular oil. Sometimes it's part of the detergent package, used to decrease yellow metal corrosion. Pennzoil staff told us that the original PU's boron was used for this purpose. Other uses are borate esters which "possess friction-reducing, antiwear, and anti-oxidant characteristics" (http://onlinelibrary.wiley.com/doi/10.1002/ls.3010140404/abstract).

Thanks for the link, interesting.

Hi boxcartommie22, Moly and Boron together is not a surprise, i was looking more towards why those two are never (to my knowledge) combined with Sodium.

call dave at red line he will tell you.
