Found some 5W-30 oils ACEA A3 spec.

Castrol Edge
Castrol SLX Professional
Motul 8100 X-Max
Motul GM LL A/B 025
Mobil 1 ESP Formula
BP Visco 7000
Havoline HWSA Ultra S
Gulf Formula GVX
Gulf Formula XLE
Gulf Formula G
Gulf Formula GMX GM LL A 025
Gulf Formula ULE
Shell Helix Ultra
Shell helix Ultra AG (GM)
These are available here in Holland, they are all ACEA A3, but none is mentioning the GM4718M spec.

During the search I found a lot of other 5W-30 types .

Unbelieveable how many different types 5W-30 oils are on the market.
Engine builders first design their new engine, after that the oil companies has to design and develop a suitable oil.
