    我兩部 Benz 換波箱油都係出面車房，只係專科一啲嘅車房，都只係一般換油咁換，冇需甚 ...

各有各睇法喇.

有人話一世唔換波箱油都未試過壞波箱, 可能佢時運好?
有人話換波箱油, 由無事搞到有事, 可能佢時運差?
我上部用到湯都無換波箱油 (里數唔特別高但年紀夠大)都一樣波箱好順無問題, 可能我時運好?

有部份車講明一世唔駛換油嗰D, 無油尺無開口, 如果溫度唔啱, 會估唔到多左油定少左油.  而部份sensor 無話防止急速溫度而加強呢方面保護 (無預你打開換油), 最好跟番原廠指引 (當然街外的車房都可能做開同一款車識得跟) 但如果知自己架車冷門少少, 車房唔係專做開呢個牌子, 就唔好當成所有車都一樣咁做 (但香港好多車房的人係咁做, 你拎支油黎話啱就幫你換, 換錯油都得咁).

部份指引講明換油時溫度要 30-40 左右, 份量先準備. 太凍太熱都唔啱份量.

波箱現時變化好多, 唔係話一個牌子就一定得一款.  新新舊舊都唔同晒技術.
自己睇番自己部車用的技術同保養說明書.

我就無聽過用親愛信精機波箱都話唔駛換機油呢個講法, 日本車黎講應該無乜

日本車我淨係聽講MAZDA SKYACT ...

Not AISIN, but I have 2 identical Subaru turbo cars with CVT:
same year, same model, one silver one white.

Factory owner's manual says Lifetime CVTF.
Dealer said change CVTF every 20,000km because HK model is different, and we have harsher environment than Middle East sandstorm, 40*C desert or -20*C winter, poor petrol quality and worst traffic jam.
I changed the CVTF on the silver one , but did not change the white one.

Before change, they all make the "gung" sound and kick when shifting from D into R or R into D.
No funny noise or kick after change.


I also have a Toyota Hybrid.
Owner's manual said CHECK AT 100,000.  Dealer said no instruction for change.
I changed myself at 80,000 and 120,000.
At 80,000 the fluid was black ink.  Hybrid motor was much quieter after change.
At 120,000 the fluid was clear pink.  No difference after change.


I also have a Benz.
Owner's manual said Sealed Unit with Lifetime Fluid.
I changed at 15,000 and I felt much faster shifts.


I also have a some MT cars.
I feel smoother shifts even change at 3,000.

咁係model 唔同定操作環境唔同?

另外香港係 poor petrol quality ?

愛信副6部/8部波箱賣到通街都係，但大部分都係話終身免換油....
(TF-80SC, TF-81SC, AWF8F35，有用上既廠有
Audi / BMW / Fiat / Ford / GM / Hyundai / Jaguar / Land Rover / Mazda / PSA Peugeot Citoren / Renault / Suzuki / VW / Volvo )
即使車廠點講終身免換油但已經大把案例唔換油就十萬公里，換油就三四十萬不是夢。

新既好多表面已經見唔到油尺，上面講嗰幾款(加上本身豐田車)個油尺已經整合左去個放油螺絲度。變左另一種做法啫，自動波波箱去到覺得唔順先去換油已經係太遲...

仲有附帶，豐田隻T-IV油同WS油個冷縮熱脹幅度好大，所以唔跟手冊去CHECK油量到行車時試過可以差成一升

Typical HK Dealer / Garage bullshit, always saying that HK environment is too hot and too cold blah blah blah

Ford Duratec and Ecoboost engines are all specified to use 5W-20 engine oil after Service Bulletin issued, yet a lot of parts store/ garages say it's either -20 is too thin for Hong Kong or 5W is too thick for startup protection.

When I went to Dubai I asked the dealer there what oil do they use in the summer? 5W-20
When I went to Finland I asked the dealer there what oil do they use in the winter? 5W-20



As a side note, when a lot of garages and parts store see what oil I use for my car they were all in horror.....

我就渣唔到幾十萬公里喇. 對我黎講夠一世了. (我係mazda skyactiv 唔係愛信, 有lockup )

不過我唔反對人換油的, 唔爭論喇. 個人選擇, 去到八萬十萬, 有人賣車, 有人換車, 有人想渣一世.  只係叫大家注意番部部車要求唔同, 如果仲係學廿年前的日本車咁, 求其搵車房用同一方法換新的AT 油, 就真係自己小心喇, 唔換好過換.

呢樣先係真正死因，班車房佬一招走天涯年中唔少無咁大路既車就咁整死。

整死仲要賴話架車唔好設計有問題呢下仲心痛
