I have always heard that European oil standards (ACEA) are more rigorous than American API standards. I can see that for SN, SN plus, SP.
But playing around with the lubrizol oil spec comparison tool, I thought that the dexos 2 standard came pretty close.
Are there other categories, than those listed in the tool, whereby A5/B5 shows itself to be significantly better? Or has dexos 2 closed the gap?
One more question--"aftertreatment compatibility"--does that mean measures like zinc limits, to prolong cat life?
