none of the above.

1. a lot of oil additives are useless.  for instance;

2. don't pay a lot of money for something where you don't know exactly
what it is.
3. even if you find "information" that purports to tell you what it is,
chances are it's incorrect and that the manufacturer has gone to great
lengths to keep that information out of the public domain where
consumers can then form accurate opinions.  "synthetic oil" for example.

bottom line - just use a good quality branded oil.  some are worth
avoiding, [like motorcraft which plays heck with seals on older
vehicles] but otherwise, save your money and enjoy honda reliability
using standard motor oil like you buy in woolmort.

Disregard my last message! I was replying to the Subject line, not the body
of the message, which was very different from the Subject line!

I second what jim beam said! DON'T put ANY additives in your oil. Additives
are a dumb idea.

Use any name-brand motor oil and a Honda filter.

NONE of the above!

Only alternative to Honda fluid is RedLine...

Stay away from the additives.  Use any major brand oil in the weight
your manual calls for.  Change it at the severe service intervals.  Use
a quality oil filter.  Stop worrying.
