Interesting letter from Shell Oil engineer
Not to start a controversial EARL thread here's an email from an engineer at Shell that I found on the Shell forums....Anyway, I thought you guys might find it interesting.
"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."
If you have any additional questions please call us at 800-231-6950.
Thank you for your interest in Shell products."
