Thank God that 450 does not take that much oil!!! LOL!!!I use the Maxima synthetic 530 it is a full synthetic but kinda of pricy around $15 a qt but as long as you run an oil that meets the JASO T903 standards you will be fine, i am thinkink about the Amsoil formula 4 stroke synthetic it is some good oil and about 1/2 the price.

I know about the rebuild stuff and synthetic its so slick it wont let the rings seat properly and will cause the engine to use oil.
