I know it's JASO MA2 rated so OK for , wet clutch, but I understand the "S" (for spark ignition) API ratings confirm suitability for gas engines and address certain additives which damage the catalytic converter (we have one, right?). As for the BRP oil, not only is it expensive, but it also breaks down well before 9,300 miles (more like 3,000-4,000) and it's a semi synthetic. Would appreciate feedback on this from more experienced owners. Thanks.
