Hydrogen can also corrupt the structure of metals in which it comes into contact - see Hydrogen Embrittlement
That's awesome information, thank you. Hopefully it was obvious that I was speculating as to why one chemical is used over another.

So, what is your take on the hydrogen injection stuff? I'm very interested to know.

I haven't bought into the hydrogen thing just yet. But the MPG numbers are hard to argue with. On the surface, anyway.
