BMW X3 28i F25 LCI Maintaince Gearbox oil change 保養紀實:變速箱油
長久以來的大哉問:自排變速箱油該定期更換嗎?
古今中外,大家都在問,都在爭議的問題:究竟,我的自排變速箱油,要不要定期更換?為什麼原廠都跟我說永遠不需要更換,與車同壽,這是真的嗎?
肥宅接觸過實際養護較多的兩台車:CX-5, F25X3, 一台使用的是日本愛信六速變速箱, 另一台使用的是德國 ZF 縱置八速變速箱 (8HP45XHIS-116)。相同的是,汽車製造商原廠都給出:變速箱油非必要不需要更換 (FLUSH),的建議。
身為難以被說服的肥宅自然無法接受這種與過往邏輯違背的理論。首先到變速箱製造商 ZF 原廠網站進行查找,發現其實 ZF 是有提供該變速箱的保養套組與建議的!
(備註:8HP45XHIS-116 建議文件)
文件中提到:
5-, 6-, 8- and 9-speed as well as 4HP20 automatic transmissions:
ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are
filled maintenance-free with specially developed partially synthetic ATF oils.
filled maintenance-free with specially developed partially synthetic ATF oils.
Maintenance-free fills are intended for normal operating conditions. Especially driving at very high operating temperatures can result in accelerated aging or increased wear of ATF oils. In case of above-average operating conditions, such as:
- frequent freeway driving in the upper speed range
- offensive, sporty driving style
- frequent trailer operation
it is recommended to refresh (change) the oil of the automatic transmission every 100,000 km or no later than after 8 years. In each case, only released ATF oil may be used for oil changes. And oil changes must be performed in accordance with the relevant specifications.
也就是說,原廠說得正確,也不正確(介於有與沒有中間!?驚!?)
既然是這樣,車子的里程也近十萬了,二手車,上一手的使用狀況不明,保險起見就當作上一手都在用力操駕的假設,來換油吧!
更換時間:7th, Sep., 2018
更換時總里程:91556 KM
拆下後的變速箱油濾網,只有一個小小的洞可以看到濾棉,確實有點髒髒的。
新的變速箱油底殼含濾網,不過不是原廠品,貌似一個美國廠商所做的
同場加映:
更換內外冷氣濾網,OEM 廠件。
拆下來已經髒透了的濾網,難怪我都覺得冷氣臭臭的...
說實話,更換完後比較有感覺的應該是冷氣濾網,變速箱油的話,其實本來就沒什麼大問題,換油好像比較是一個換安心的感覺囉!
