I've always used Castrol 5/20 since I bought my rx8 3 years ago and haven't had any problems, but defenitely will like to extend the life of my engine like many other.

Are any of the oils by this manufacturer good for the Renesis?

By the way this aint a duplicate thread, the other thread is about the premix by the same brand Idemitsu.

 

yes,

this is not a premix thead.. as you are in pr. i would think about a 5w 30 or a 10w40 at the least...

and the premix thread is what it is.. read learn..
