[詢問] 紅線5W50長途 中壢到高雄

其實redline上面的認證是自己寫爽的

並沒有真的送驗

而實際有送jaso認證的

印象中要先有過API SG~SN OR ILSAC GF-1~3 OR ACEA其中一個

另外JASO 的認證主要是因為現在的機油朝向低黏度低摩擦發展

所以他們擔心離合器打滑才設立的認證

所以JASO MB就可以當作汽車油

汽車油本來就可以給速克達使用

下面節錄JASO 4行程汽油引擎機油手冊第二頁第二點

In recent years, engine oils for 4-wheel vehicles have tended toward lower viscosity and lower friction to achieve better fuel economy.
There are concerns that such low friction and low viscosity oils, when used in motorcycles, may cause clutch slippage and transmission gear pitting wear.
Therefore, standards specifying a test method to properly evaluate the oil quality and specifying the oil performance classifications to be determined by the test method have been established by JSAE.

原本預計半夜騎的 可是中壢下大雨...

結果早上9點30分從中壢出發
下午6點10分到高雄 總里程 370KM
安全到高雄了  
謝謝各位提供的行車安全意見:)

那是1994, Dr. John Woolum tested the viscosity of several 10w-40 oils in his motorcycle.

不過這個外國人到是推5W40柴油用機油用在機車上

文中提到 Dr. John Woolum tested

In 1994, Dr. John Woolum tested the viscosity of several 10w-40 oils in his motorcycle. He found that all of the petroleum oils had lost highly significant amounts of viscosity within 1500 miles. Only Mobil-1 held up in his test. I have personally tested Delvac-1 synthetic in my ST1300. It was 5w-40 when I put it in, and 5w-25 9,200 miles later. By 1500 miles, the petroleum oils Dr. Woolum tested were at 10w-25 equivalent. By contrast, Dr. Woolum tested a petroleum oil in his Honda Accord. After 3600 miles, the 10w-40 oil was 10w-37 equivalent. Motorcycles are indeed significantly harder on their oils than cars. Based on this result and the VI numbers above, it would seem that 10w-40, 5w-20, and 5w-30 oils cannot be safely used in motorcycles for more than 1,000 to 1,500 miles.

希望對車友有所幫助.謝謝!

那天去高雄昌庫 買紅線
黑瓶比白瓶貴
白瓶比黑瓶濃
老闆還跟我說 汽車的 機車 也能用
