乾式離合最常見因...(恕刪)
其實我個人認為還是要看車主騎乘的習慣,我每次騎車大概都在30KM以內,如果使用20W-50的機油,天氣寒冷時大概到達目的地機油還沒熱開呢,沿路大概油門都是澀澀的,目前我用的是中油10W-40 with jaso ma ,夏天大概3~4KM就能感覺油熱開了(油門變比較輕了)。
這裡有個MOBIL官方網站

裡面有提到汽車機油和汽車機油的不同,請樓主參考看看吧~~
至於該不該使用JASO MA我就不是很清楚了~~我的車主使用手冊寫要用,我就跟著使用有ma。
有人濕式離合器用汽車機油也沒怎樣,我自己覺得車子是自己的,要給車車喝那種機油由自己決定吧,壞了也不過就是台機車嘛!!

不喜歡可以不要用啊
以下文章可以參考看看 ..
請按這裡(英文) 我就偷懶不翻譯囉....
The results of these tests seem to support some of the long-standing theories about oils while casting serious doubt on others. Going by these tests it would seem logical to assume that:
1.The viscosity of synthetic-based oils generally drops more slowly than that of petroleum-based oils in the same application.
2.Comparing these figures to viscosity retention for the same oils when used in an automobile (see later text by Prof. Woolum) would indicate that motorcycles are indeed harder on oils than cars.
3.The fastest and most significant drop in the viscosity of petroleum-based oils used in motorcycles occurs during the first 800 miles (or less) of use.
All of these results (1-3) agree with everything the oil companies have been telling us all along. However, the same test data also indicates that:
4.The viscosity of petroleum-based oils, whether designed for auto or motorcycle application, drop at approximately the same rate when used in a motorcycle.
5.There is no evidence that motorcycle-specific oils out-perform their automotive counterparts in viscosity retention when used in a motorcycle
