Royal Purple Oil

[CNS-Mike]

Desmo,

That's cool.  I can barely remember sh*t from last month, much less something obscure from 10 years ago!

Back to using Royal Purple in bikes - here's a question:

If the stuff cost's twice as much, wouldn't you be better off just changing your oil twice as often?  Is there a benefit to having an oil that's such low viscosity that your engine idle has to be turned down?  Would you see that as in increase in output (at the wheel) since the engine isn't having to work so hard to sheer a "tough" oil film as it fires?

My amsoil is like 10 bucks/qt and I trust it.
