Just a curious question, do we have any idea when the next API catagroy (API SO? (maybe SP since the letter "O" looks like the number "0" in some fonts)).
It was late 2010 when the SN spec came out (same time as the HDEO CJ-4 spec, which was recently updated to a CK/FA-4), and a lot has changed since then. Small turbos are more and more common, and change intervals are increasing.
Quick review:
There have been many other manufacturer specs that have come out since SN was released because API is not keeping up (Dexos, ACEA, BMW LL etc).
Not that it would really make a difference for me, I don't plan on having a vehicle that would require it for a long, long time, even if released this year, but I was just curious what (if any) status it had, and if any idea what the changes in it would be.
