i couldnt find info in the owners manual, shop manual, or the clymers, though it recommended for es models, maybe all. owners had SAE with API SF or SG. JASO has grades as well, MA-1 through MA-5. I think there is a thread here that covers that, i cant find it as well. the castrol im used this time is rated JASO MA-2, API SG.
i was thinking for some reason i needed the JASO MA-4. Just too many letters and numbers, for my criss-cross brain to keep track kcuff.
