Which oil is the best for EP2?

[Dragon_F]

Hi,

I would like to ask you which is the best oil for ep2.  I am using for my EP2 the 10w 50, but i heared that i can use the 10w 40 or the 15w 50.

But i don't know which is the best for my engine.

Can you please help me? 

Thanks  :)

Honda recommends 10w 40 usually Castrol GTX Magnatec semi-synthetic, you can put fully synthetic oil in, won't do it any harm but will cost more though, I wouldn't use 15w grade as it's too thick for this cold weather.
