Mootoriõlid peavad vastama viskoosusstandarditele, sealhulgas ka pisipöörleva viskoossusmõõturiga mõõtmisel saadud väärtused, et neid saaks liigitada SAE J300 viskoossusklassidesse, ja see nõue lisati pärast seda, kui 1980-81 ja 1981-82 aastate talved põhjustasid USAs ja Euroopas suuri mootoriõli pumbatavuse probleeme.
Engine oils must meet viscometric standards including those determined by the mini-rotary viscometer in order to be classifiable within SAE J300 viscosity grades, and the requirement was added after the winters of 1980-81 and 1981-82 caused major pumpability field problems in the US and Europe.
