Boron

[Max_Wander]

it looks really impressive as an FM and AW additive.

For one, it's ashless which appeals to GF-5 and above that will most likely demand lesser ash. It also can adhere chemically with iron surfaces, securing it's place.

Anyone interested, check out this article http://www.rtvanderbilt.com/news_19.htm

This seems like a dream come true for any rotary engine owners out there

There is a lot of info that was provided by Molekule on boron. It's been used for quite some time in PCMO's.

If I recall correctly, Mobil and Motorcraft were two of the first oils to use over 250ppm of boron in their formulations. Mobil now uses about 80ppm of it while Amsoil is using 260ppm in ASL/ATM formulations.

Yep, RT had developed the esterified boron around the 2003-2004 time frame.

A company that used to advertize here used this component in PCMO's and gear lubes.

nice writeup in the thread buster linked. Boron levels in OAs suddenly means a lot more to me now. Have a feeling I might cheat on my Moly! Things havent been the same between us since I met Boron

Do you think vanlube would sell some to the regular consumer?

Delo 400 LE is loaded with Boron, almost 600 ppm IIRC.

Maybe that's part of why it seems to do just as well as (if not better than) the CI-4+ oils?

Many different additives can be boronated and it's not just anti-wear additives like borated esters. Detergents and dispersants can be boronated. If you search online for patents on boron you may find what I learned about it. We don't know what type of boron additives different brands use, so little conclusions can be drawn. That's not what we want to hear but it is so often the case!

I recently asked R.T. Vanderbilt if they can sell their additives to just a regular guy like me. They said no because they are bound by some kind of chemical legal agreement or law. I forget what they called it. I was very bummed out!
