Which oil for stage3+ FZ
Is OEM oil Yamalube good enough to use in a heavily modified SHO engine?
We are planning to turn +8.500rpm w/ all the goodies soon after break-in, and wondering which grade of oil is best for our new operating temps
What are the pros using? fully synthetic 5-50?

most will get away from yamaha oil and run amsoil 10/40 marine,or a good quality oil if they cant get amsoil,
i have search in the last few days and found loads of good oil in sho/fzr threads with great info have a read and go from there but i would recomend a better oil in any sho/fzr but im no expert..

I've been running Amsoil for over 70 hours in my SHO.

I never heard of anyone have problems with the OEM oil. With that being said, I use Amsoil oil with Yamaha filters. Lookin for a better filter

In light of the issues with the supercharger bearings at the moment and the fact that I'm pounding the hell out of my ski and motor offSHOre....
I say go heavy...get a thicker layer of protection in there......40w

Thicker is not always better.
If the tolerances call for 30 then do 30.
I had a Toyota once that called for 5/30 and I ran 10/w30 and the check engine light came on because the knock sensor picked up too much knock.
After a call to the service dept. he told me to run what it called for that the 10/30 was too think to get into the bearing clearances and a change to 5/30 would solve it.
They were right.
