Has anyone ever tryed Royal Purple Synthetic motor oil in the 155 Rotax motors? If so how did it compare to Sea-doo XPS synthetic. Also has anybody tryed 10W-30 in the non supercharged version. Sea-doo recommends there XPS 10W-40 but being a 4 stroke engine similar to a high reving car engine I would think 10W-30 synthetic would do just fine. Any thoughts would be appreciated.

Engine Oil??
