Hi all!
I am from South Africa, but this is one of very few forums where people have actually tried Boric acid/oxide in their engines, which is why I am reviving this thread.
I have done so also, but with a very different method to the way you people have done it.
The cars I have done this to with my method have all shown huge improvements within 2 to 3 km!
Except 2*
You do this by doing a bit of research and using your head:

Boric oxide + water = boric acid.
So rather than relying on moisture in old oil to react with the oxide; I added enough water to make it ... watery and poured it in!
I have many reservations about doing this.
Like the large particles blocking the oil filter... (20-45microns filtered)
What the stuff becomes when reacting with nitrogen and hydrocarbons at the temps and pressures found in engines etc.
(this was the subject of a lot of research for me)
How is everyones cars long term that have added Boric oxide?
It has been in my car for 8 months now.
*NB: the water thins the oil and can lead to the oil light coming on.
add slowly for really old engines and switch off immediatly if the light come on.
I look forward to hearing from long term users!
