I'm in the process of trying to determine if the new Rotella T 15W-40 with Triple Protection (the new CJ-4 stuff) happens to meet the requirements of JASO MA as well.
Note: I know it does not carry the JASO MA certification. What I'm looking to determine is if the characteristics of the new Rotella meet the JASO MA specification.
Here's what I currently know meets JASO MA:
o API rating -- JASO MA requires SG, SJ, SH, SL or SM. Rotella 15W-40 Triple Protection is rated SM so it meets JASO MA.
o Suflated ash -- JASO MA requires no more than 1.2% of mass. The new Rotella 15W-40 rates 1.0% of mass for suflated ash. Therefore, it meets JASO MA.
o Phosphorus -- JASO MA specified a range of 0.08% of mass to 0.12% of mass. A virgin Blackstone analysis I saw showed 989 ppm of phosphorus, or 0.0989%. It meets JASO MA.
High Temperature High Shear -- JASO MA requires 2.9 mPa-s or better. I read elsewhere the new Rotella 15W-40 has a value of 4.1. It meets JASO MA.
There are four other qualifications to meet JASO MA, and I do not yet know how Rotella T 15W-40 Triple Protection matches up:
1 - Evaporative loss (JASO MA: 20% max)
2 - Foaming tendency (JASO MA: Seq I - 10/0 max; Seq II - 50/0 max; Seq III - 10/0 max)
3 - Shear stability (JASO MA: 12.0 mm2/s for xxW-40 weight)
4 - JASO T 904 friction test outcomes DFI, SFI and STI (Table 2.1 in the PDF referenced above has the test specifications required for JASO MA)
I have an e-mail into Shell, but I've not yet heard.
Does anyone here happen to know how the new Shell Rotella T 15W-40 Triple Protection rates on those remaining four qualifications?
(Please don't report on the synthetic 5W-40 ... my focus is really on the new CJ-4 Rotella T 15W-40 Triple Protection.)
Thanks!
