[分享]關於檔車用油認證JASO MA的解說

剛好最近又有人在討論檔車用油的問題

其實這個問題也困擾我一陣子 兩陽的原廠性能型機油都沒有JASO MA

偏偏KTR 野狼又賣得很好 這個用油問題就越滾越大

爬了一下國內外網站

找到一個解說比較完整的 內文如下:
New JASO oil standards (MA1, MA2):

JASO effectively added the JASO-MA2 & JASO-MA1 specifications by splitting the existing JASO-MA spec into two groups by friction-performance (MA1 is the lower friction oils; MA2 the higher friction oils suitable for bikes).
The change came out as final/approved in 2006 in response to catalytic converters becoming widespread in bikes (EPA/EU requirements); it was also prompted in part by the car-lobby of the JASO organization wanting to specify a subset of the JASO-MA oils for use in their cars (the low friction oils, which become JASO-MA1). JASO-MA2 is just starting to show up in the US Market as a rating because this is the first year that catalytic converter-equipped bikes are widespread.

Aside from splitting the MA spec into two sub-groups, the new specs add a phosphorous content ceiling (better protect catalytic converters by using less, but phosphorous is also anti-wear additive, so it could be less start-up protection). JASO-MA2 being the heavier friction oils most suitable for motorcycle use will become the common standard for Japanese-built (and many Euro-built) motorcycles for the '08 and later model years.

Note that JASO-MA2 can now be API SJ formulated, but API SL & API SM formulations still directly contradict JASO-MA/MA1/MA2 standards because of the use of friction modifiers that are not wet-clutch compatible.

The JASO-MA (no suffix number) still remains in effect as well. For the Kats, API SF/SG + JASO-MA rated oils will remain the oils of choice until they are no longer available.

簡單來說JASO MA是檢測其機油潤滑的添加劑是否會造成打擋打滑 還有是否含有保護離合器的添加劑

而MA MA1 MA2之間所謂的差別也不是外面說的跟速克達潤滑有關

MA的等級是在於表示機油的止滑性(防打滑性)

而其等級標準分別是

(止滑最少)JASO MA<JASO MA1<JASO MA2(止滑最多)

所以今天在機油的選購上

速克達可以選用只有JASO MA的油品EX:SHELL ULTRA10W40

檔車打擋不順可以選擇JASO MA2的油品會比較理想 EX: TOTAL RACING 4T10W50

希望本文可以解決檔車用油迷思

感謝樓主分享
我倒是想想找 MB全合成 10W50的 或10W40也好

還好我是化油車．．．

這是有沒有離合器的問題吧??

止滑性真的是與離合器片壽命長短有很大關係.....

這和Ｏ２　感應器也有關．．．

只能說，　化油車有本錢玩很好的油．105.gif

供油系統
                          是不同的吧.....

看了你這兩個回應
我真的很想問...

你懂機油嗎?

我怎麼看都是兩個不相關的事情.....

JASO MB MA MA1 MA2 差別如下



速克達以 JASO MB 為優先選擇
檔車依離合器設計,動力,看會不會打滑 選擇 JASO MA  MA1  MA2

所以MB的是速克達專用，檔車用會狂打滑嗎??

應該這麼說好了
有MA基本上就是廠商保證不會打滑
沒有MA的話不一定會滑，但也不保證不會滑
