I tried looking online for the specs on this oil and i cant find anything. Castrols websight is pretty vague. I see the oem approvals on the jug but i was just wondering if it met any euro specs. Or honda turbo spec. It seems to me that the oem specs on the back are rather weak. Most dino will meet them. It does meet the gm dexos spec so i guess its a good oil. Also be nice to see a voa of it soon.
