係啊 不過保險未判邊個錯都會怕 知道對面100%錯就放心曬

星期日同屋企人飲完茶，發現架車畀人H&R，以為冇仇報。返屋企睇番dash cam，見到泊我隔離架白色RAV4司機出車，撞完褪翻後扮冇事再揸走，仲要快速揸走！警就報咗，片有對方車牌，條友等畀警察搵。

呢個爭論其實都嘈咗好耐，如果regular同premium真係冇分別嘅，油公司應該畀人告導誤告到甩褲至係㗎，但從來冇人搞集體訴訟⋯⋯

利申～我入94，架車要入premium而唔入，有事被人void warranty就喊都無謂

唔係無分別
it depends on the engine
佢個test係拎一副淨係design for 87既engine去試87同91有咩分別

但如果佢副engine係design for 91既 個test result就會唔同

而佢話可以入87既車唔洗入91 入左只會增加incomplete combustion
呢樣野係correct to a certain extend

因為有engine係designed for multiple grade gas
佢既電腦&sensor係可以因應唔同fuel去改變ignition timing&compression ratio
從而達到more complete combustion&more power
but it requires the engine&ecu being designed with that in mind
而大部份engine都冇咁做(mazda skyactiv is ab exception)
就算你入premium fuel佢都淨係用番同一個compression ratio同ignition timing, result就係多左incomplete combustion
所以佢個statement先可以mostly true

多謝你嘅詳細解釋～ 佢嘅講法好合理

以前聽過某一派嘅講法係⋯⋯乜引擎用平/貴油係冇分別

Its all about the engine design
Usually with more powerful engine, a higher compression ratio and tighter ignition timing is required to extract most energy out of the combustion
And in order to achieve a high compression ratio, a higher octane fuel is required to withstand the high compression before it ignite itself prematurely (pre-ignition)

Using regular fuel in a engine designed for premium fuel, it will result in knocking and pre-ignition, which can damage the engine.

你地會唔會定期打蠟/polishing 定係出街搵人打 之前洗得發發發多 發覺花花地

發發發咪幫緊你部車磨沙囉

以我認知最容易分就係睇你係NA定Turbo
NA一般冇咩要求
Turbo就要入貴油
利伸： 睇Youtube睇番黎

之前揸Mazda無
依家揸Lexus有

你就想 日產NA v6就要91先有動力 福特v6入87就得 r洲車全部都要 Toyota 同爛仔車 唔同油會自動較個ratio

mazda副2.5t可以入87
vw gti 2.0T都可以入87

有啲網話星期日入油平啲，又有啲網話夜晚入平啲，究竟係點？

我呢到Calgary 無呢啲野

夜晚10點最平

由每日00:00開始係最貴 跟住隔幾個鐘(冇定)就平啲啲 直到第二日嘅00:00嘅新價

星期日 可以平 可以貴 可以冇變

我就每日自己睇定第二日嘅價先決定入唔入油住

如果搬去大溫係咪應該出返架電車

屌依家16x貴撚到戇鳩

揸緊Lexus v6 na 要91

溫哥華20x
好似話夏天仲會上到23x
我已經準備通勤重投Translink懷抱

出返架ev 溫哥華唔洗怕凍得滯

Direct inject 可以點清？
