'We recently ran the JASO MA friction test on Rotella T with Triple
Protection 15W-40, Rotella T Synthetic 5W-40 (CI-4) and our soon to be
introduced (within the next 2 months) Rotella T Synthetic 5W-40 CJ-4.
All three oils passed the wet clutch friction test. Rotella T Synthetic
5W-40 (CI-4) has more than 1.2% ash (JASO MA spec limit) so it can not
be classified as JASO MA. However, Rotella T with Triple Protection
15W-40 and our soon to be introduced Rotella T Synthetic 5W-40 CJ-4 do
meet JASO MA."
