Guys, I've been searching for this type of info for many days and finally managed to get it... I just don't understand why Castrol does not mention technical information in their data sheets / websites, etc... generally they don't even mention the grade on the oil bottle!!!
Took the info from
Power 1 Racing 4T 10W-40 (2241)
But then, though the site mentions as the latest update to be pretty recent, the bottles we saw in shops were JASO MA2 & API SL!!!
Power 1 Racing 4T
