What would be the best oil to run in the Blaster transmission?

 

yamalube #4 oil

 

What weight is the Yamalube oil? 20/50 or 20/40 or something close?

 

I've been running Castrol 10w-30 oil in my tranny for 3 years. No problems.

I ran castrol 10w-40 but switched to spectro golden transmission oil and I think it really does shift smoother like they say.
