Announcement from the Implementation Panel

　

Announcement on the revision of the "MOTORCYCLES-FOUR-STROKE CYCLE GASOLINE ENGINE OILS(JASO T 903)IMPLEMENTATION MANUAL"(2023. 5) We would like to inform you that the JASO engine oil standard implementation panel revised the on-file standard implementation manual according to the revision of " MOTORCYCLES-FOUR-STROKE CYCLE GASOLINE ENGINE Oil Standard (JASO T 903:2023)". The significant changes in Standard and Application manual of the latest revision include: (1) The changes of engine oil performance classification criteria : As for the API standards documented in SAE J183, SG, SH standards were deleted, and SN PLUS, SP standards have been newly added. In addition, the ILSAC and ACEA standards were deleted from the applicable engine oil specification categories because there was no record of T903:2016 on-file list. (2) The revision of physicochemical properties : Through the investigation of T903:2016 on-file oils listed in October 2019, the phosphorus specification has been changed from 0.08-0.12% to 0.08-0.10%. In addition, the specification of evaporation loss has been changed from 20 mass% or less to 15 mass% or less, which is equivalent to other standards. (3) The revision of the “Reference oil”, “Friction plate” and “Performance classification according to friction property indices” : Since the manufacturer raised the supply issue of the reference oil (JAFRE-B16) used in the standard, alternative reference oil was investigated. After the study, an alternative reference oil (JAFRE-B23) was selected in consideration of future availability and friction properties. Moreover, since the friction plates used for the evaluation test were in limited supply, a modified alternative plat was selected for enhancing availability. In accordance with the changes in the friction plate and reference oil (described above) for this test, the index performance criteria were also revised. (4) The addition and revision of the effective period for standard conformity oil(This revised points is shown by the red.) : Year of Issuance of the Standard First date when Classification Indication is allowed Last date when new filing is accepted Last date when on-filing is maintained 2011 October 1, 2011 September 30, 2016 April 30, 2021 2016 October 1, 2016 September 30, 2023 April 30, 2028 2023 October 1, 2023     (5) The revision of performance display format : (This revised part is shown by the red.) old manual revision manual In case of on-file as MA or MB (X = A or B) In case of on-file as MA1 or MA2 (Y = 1 or 2) Concerning details, please confirm a revision manual(4T_EV2305.pdf). * Official commencement of the performance display will be start on October 1, 2023.
