I just read SAEJ300 where HTHS is 2.3mPas
min. on SAE16 ( it's 2.6 on SAE20)
I knew this last month or prior and forgot it.
I also think the KV100 for 20 got moved closer to 7cSt and 16 MIN is near 6cSt
Gotta keep up if anyone asks me questions at cocktail parties;
being a long term forum member has it responsibilities
