Not a U.S. marketed product. ACEA A3/B4 So high HTHS Full saps lubricant which should make for a great HD all rounder.

The proof is in the running not parsing tech tidbits. Use with confidence. What engine again? You asked the forum to choose between two oils a few days ago, I guess this one came out ahead.

Magnetec = Great Product
ACEA A3/B4 Great oil spec.

What's the worry?
 
Castrol self-certifies that it meets API SP spec and I wouldn't hesitate to trust a company like Castrol. They aren't going to pay for the donut in countries that typically don't care about "American" specs though. I am surprised they don't list at least a JASO spec.

It means what they want it to mean. If I were to guess I would say it is a high(er) VI non-hydrocracked oil much like Chevron sells.

Technology improves, if you want an ACEA A3/B4 oil then go for it. That’s your marker of proven performance.
 
It is tricky since OP is in Asian Country which have oil sold in that region.
They have different labeling standard and viscosity standard.

I don't see why you cannot use the oil.

FYI, API is American Petroleum Institute which is a standard here in the US.
Not sure what standard is used in Asian countries.
