去 ASS 換機油 , 老闆說 address 要用原廠噴射專用機油會比較好.
不過一罐要價 400台幣. 真的有必要用到這麼好嗎?

What will damage my oxygen sensor?
Answer
An oxygen sensor can fail prematurely if it becomes contaminated with phosphorus from excessive oil consumption, silicone from internal coolant leaks, using silicone sealant in the engine, and some over-the-counter fuel additives. Even a small amount of poorly refined gasoline can kill an oxygen sensor. Environmental factors such as road splash, salt, oil, and dirt can also cause a sensor to fail, as can thermal shock, mechanical stress, or mishandling. However as required by vehicle manufacturers, Bosch sensors are designed and tested with these extremes in mind.
問:
啥麼東西會使含氧感知器損壞?
答:含氧感知器會永久損壞損,因為被機油中的(磷 phosphorus)好像是過高的ZDDP(二烷基二硫代磷酸锌)污染,所以有含氧感知器噴射引推測應使用API SM 的機油有限制 磷的含量
其他像 汽缸墊片破損使冷卻水中的矽 silicone 污染,使用含矽的汽缸膠,或過量的汽油精,品質不量的汽油,熱震盪,不當的安裝都有可能使含氧感知器永久損壞損
再參考MOBIL 1 檔車機車Motorcycle用機油 的問與答
https://www.mobiloil.com/USA-English/MotorOil/Oils/Motorcycle_Oil_FAQs.aspx
Additive packages balanced differently for motorcycle engine and transmission operation. For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers. Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum. Motorcycle oils allow the use of higher levels of antiwear additives such as ZDDP (phosphorous).檔車機車可以容許較高的ZDDP(磷 phosphorus)
上文大概的意思為
檔車機車Motorcycle 的引擎與變速箱設計為一體,都是由引擎機油來潤環此兩個系統
但是機車引擎與檔車機車變速箱對機油添加劑的性能要求卻是相反
對汽車噴射引擎機油也就是指單獨針對檔車機車引擎的部分來說,省油與對排氣處理統(包含含氧感知器的使用壽命)為最優先考量(剛好與噴射引擎速可達機車SCOTTER或稱為小綿羊的機車要求相同,使用乾式離合器皮帶傳動,機油不會影響離合器的性能)
所以汽車噴射引擎機油的含磷 phosphorus量必須降低並且使用一些摩擦調整劑( friction modifiers )降低引擎零件運轉時的磨差阻力,並減少活塞環與汽缸壁的摩差,提供省油性能,最適合噴射引擎速可達機車SCOTTER或稱為小綿羊的機車使用
摩擦調整劑( friction modifiers ) 成份大都是 "鉬"
可參考日本HONDA官網的介紹
http://www.honda.co.jp/study-motor/contents/engine-oil/syousai-page/index.html
檔車機車Motorcycle 不需要摩擦調整劑( friction modifiers )來提高省油性,同時防止檔車機車濕式離合器打滑,因為檔車機車的離合器設計為浸泡在機油中,也不適合在機油中添加摩擦調整劑( friction modifiers )
提供參考
因此 噴射版的機車請使用API SM 或 ACEA A3/4 認證的機油對含氧感知器最好
