I use Motorex forl oil. http://www.motorex.com/index.cfm?oid=1147&lang=en&webtoolDbTemp=eintragDetail&eintragId=98
It works OK . I do not know if it is better or worse. I read 10W-30 for CB750 and Motorex had it = purchase.

I use regular 15W fork oil in just about all the vintage 70's bikes, but have used ATF and motor oil with no problems. You could probably run Canola or Peanut Oil, JK  ;D in the older street bike forks. They are just not that complicated and aren't like today's modern cartridge forks.

Save it, its expensive.   ;)

Now they sell it to us as a Vitamin Supplement. Just think of taking your daily dose of old fork oil.  :o

The Japs use that highly coveted, very rare now, white (smelly) fish oil. Ever take apart an old set of forks, you know what I mean. Save it, its expensive.   ;)

Doesn't that come from the livers of rare endangered SandCast Cod?
