dont Mazda euro sleds have a higher compression ratio as well as different regulations for fuel. Which may have an effect on lubricant selection as well as possible different formulations being deemed optimal.
So not a consistent comparison once the various different variables are included.
It's possible that the differences aren't worth mentioning,or they might be important. I am not familiar with any japanese vehicles. I like big ,simple engines with large volumes of torque,and I like to service my property and since I'm familiar with domestic vehicles I'm comfortable sticking with them.
You are right they have higher compression in Europe. I cannot say if that has anything to do with the oil specs. But I do know for sure that the older Mazda mzr engines where identical in Europe and the US. And back then there where still a difference, the Europe spec was 5-30 and the US 5-20.
It was the same when Ford used those engines under the Duratec name.
