BUT as of today, if you if you still had to use a 5W40 oil which one would it be? (Which has the most certifications/approvals?)
To answer your question.. I think the most certs is Rotella 5w40
API: CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4 ACEA E9, JASO DH-2, Cummins CES 20086; Volvo
VDS-4.5; Detroit Fluid Specification DDC (DFS) 93K222, Caterpillar ECF-2/ECF-3, MAN
M3575, JASO MA/ MA2, Allison TES 439, MB-Approval 228.
The JASO MA isnt a legit cert as far as i know..but they feel confident enough to list it.
The JASO certs that they list have created many thousands of pages of discussions all over the web from road bikes to offroad atv/utv etc etc.
The Allison TES 439 cert isnt legit as far as i know either. According to Allison T3 and T4 are but T6 is not listed whereas DELO 5w40 is.
So in summary- I dont really go by certs. I usually go with Rotella due to their robust add packs low cost and availability.
