Using info in this patent:

...some people are adding boric acid to engine...trans...diff...wheel bearing, etc.


This is a commercial version:

"Seyed Mirmiran: “Tribological Behavior Of Boric Acid Solid Lubricant”


I personally think it might be a little risky, but at least one person has added it to...I believe engine....trans, etc and reports no problems...but claims decreased friction.

I think using boron has been mentioned before...but I'd like to hear the tribological reasons for not doing this. I can hear the klaxtons going off....

Apparently...the boric acid is converted to boric oxide in the presence of water. It is supposed to act much like moly or maybe graphite.

I wonder if the powder form is at all abrasive? May depend on what it is mixed with. I understand some hardwares have a technical grade of boric acid powder that is much stronger than what you get at the drug store, so the drug store stuff must be cut with something. I would not do it. Maybe you can find a boron strong aftermarket additive instead.

A good filter might trap it all quickly anyway if the particle size is large enough in the OTC version(s).

LubriSilk tech page. Never used the stuff, just offering info on what you are talking about.

 

[TallPaul]

Wow, $35 a pint and a pint per oil change. For that price I'll forget boron and run Redline, or run Valvoline and buy a couple pizzas with the change.

Holy #@$%!! I never looked at the sales page!

MSDS shows CAS# 8002-05-9 100% "Synthetic oil with Boron additives". That CAS is for used mineral based crankcase oil! Link

IMHO is NOT boric acid is a Boron compound, Oronite has had a boron package out for?? 10 Plus years, Boron Nitride is whats used I think in the new stuff.

Once again thanks for the info Bruce. What are the price differences on Boron, Moly, ZDDP, etc. additives?

 

[marc780]

I have heard of additives made of graphite, moly, and of course teflon but BORON is new to me!!! seems like it came outa nowhere. How come the oil compamnies are not jumping on this if its so great? I think i'll wait and see!

 

[Tempest]

They already are. Take a look in the UOA/VOA areas and you will see Boron listed on the results.

If you read it carefully, it says ONE application should be good for over 100,000 miles. The reason is that it bonds to the metal instead of just floating around in the oil like the oil additives that have been mentioned.

Most Amsoil motor oils now have a decent level of B. I highly doubt it's added in it's acid form.
