450R stock air filter...what oil?

[MIA450R]

From the factory, does the 450R stock foam air filter have convensional oil in it or the new (Honda Pro-Oils) biodegradable oil manufactured by No-Toil?

I think it has motor oil on it from the factory,I use Bel-Ray on mine.

Thanks. Yeah, I am 99% sure it is convensional oil ... PJ1 cleaner seems to have completely cleaned the oil off.

Yup it is conventional oil. Personally I like the Belray stuff. I put it on the inside then ring it to the outside. That way it is all the way through the filter like it is supposed to be. And ring out the excess.
