Just perusing the oil section at my local Walmart while getting service done on my vehicle next door. Reading the labels of the Rotella T6 5w40 syn and T4 15w40 dino, both stated JASO MA/MA2 certified. Not so on the semi syn T5 15w40. But, we all knew that. I only say this as I am keeping to using JASO MA/MA2 syn/semi syn oils in my Triumph 800 Tiger while it's still under warranty. It'd be nice to have a gallon at $15 so close by. Oh well .. Walmart has Castrol ActiveEvo 10w40 partial syn motorcycle available for $18.90/gallon so that'll do..
