Announcement from the Implementation Panel


 

 
Revision of “Automotive Diesel Engine Oil Standard (JASO M 355) Application manual” (2021.05)

The JASO Engine Oil Standards Implementation Panel revised "Automotive Diesel Engine Oil Standard (JASO M 355)Application manual" in accordance with the amendments of Automotive Diesel Engine Oil Standard(JASO M 355:2021). 

The main points of the revision are as follows. 

(1) Review of high temperature oxidation test :
As for ASTM D6984 (Sequence IIIF) and ASTM D7320 (Sequence IIIG) cited in this standard, for the reason the engine supply was stopped, API had been considered an alternative test method. Since the standard value using ASTM D8111 (Sequence IIIH) as an alternative test method was decided by API in 2019, it was examined whether it was appropriate as a quality certification for high temperature oxidation test of JASO M355 and was reviewed.  
(2) Addition of the DL-2 classification :
A new classification DL-2 compatible with after-treatment devices was added. It was expanded sulfated ash standard value to ACEA C2, C3, and C5, while distinguishing it from the DL-1 standard, which specified a low sulfated ash content.  
(3) On the Filing of an Oil conforming to the Standard,
the Effective Period of On-File,
and the Indication of Classification of the Standard :

*The on-file termination date for engine oils conforming to the JASO M 355: 2015 standard:
extended from 30 September 2021 to 31 March 2022
(to be able to update with JASO M355: 2021 when updating the on-file of JASO M355: 2015.)
*The last date when a new reporting is accepted for engine oils conforming to the JASO M 355: 2017:
31 March 2022
