Many countries, like Australia and New Zealand don’t have their own oil standards, anything sold here either carries API or ACEA, but no need to carry both, even though some do.I’m saying those high phosphorus content 40 grades that used to get an SN rating, will not get an SP rating. I’m giving the American Petroleum Institute too much importance?
For years we have had oil on the shelves with only ACEA specs and no API specs (and vice versa).
My GM-Holden owner’s manual lists only ACEA Euro specs as being suitable and makes no mention of API, but then it is a rebadged Opel.
One of the most popular oils here, that is regularly on sale, and often recommended by the Castrol lube guide is the Edge 5W30 A3/B4 so I can’t see that one going away anytime soon. Thank goodness, it’s one of my favourite oils, running it myself right now.
