When the oil becomes *saturated with contaminant* particles new particles settle out of the oil onto the internal engine parts and form sludge. The point is that when you follow manufacturer's service schedule (severe or normal), the *saturated with contaminant* point will not happen before you do a service. People could be driving in severe condition but using normal service schedule, which is a common problem.
咁你覺得有幾多人其實會屬於severe condition有夕幾人又屬於normal呢? 有好多人半年連五千都行唔到, 咁算點呢? 仲有, 原廠都有sell engine flush, 三萬零左右, 咁如果換油換得夠密又點解咁早要flush? 近黎佢地又話flush唔好, 咁之前比佢地flush左果d點算?

不過根據我自己既實驗, 99年車 (98年9月買), 146k, d油4000換一次 (never add up, just every 4k), 就算係對上一個oil change (144k), 佢既condition都比好多兩/三萬公里既新車好...咁即係好定唔好呢? compare番同期既車真係冇問題同埋爽好多, 自己個心就一直都覺得好d, 眼見自己有個朋友有架同款車, 202k, 又落過場, 又去過美國中部做野, 同樣都係4000km換一次, 亦都係渣落好静好爽, 真係有d新車都冇得比喎....
I can only say different year, different driver, etc hard to compare. However, I don't agree with a car that has 144k is in better condition than a car with 30k, unless the driver of the 30k car trashes his car with no maint or whatever. Following manufacturer's schedule is enough to keep the car in good shape.[/quote]
seriously, 無論架車放出黎既油, 就連拆出黎既油隔(漏乾之後)重量都唔同, 咁當然三萬零公里既車某一個程度上黎講你新"少少"囉, 不過真係睇到都覺得可憐架; 咁當然, 如果冇要求既, 求其換左油, 入滿gas架車咪行得囉...不過幾年後架車已經比起同期既差...
曾經, 有一個朋友渣架02 Civic Si, 棍波, 一路都返廠做保養 (ave 7800km, very on time according to honda, warm up about 2 mins before drive, 94 when new then 87 when it gets older and older), 到差唔多八萬公里佢話保養期過左話唔想攞番廠, 睇完之後同佢整左一大堆基本保養都冇做好既野, 但係佢d單就話做左乜做左物, 整完佢覺得好好, 我覺得都仲係差d, 唔夠爽; 剛巧有個朋友渣同年civic, 八萬五 (多幾千公里, 我會話大同小異啦), 都係棍仔, 五千一次Motul Synthetic, 有用autostart warm車, 入89/92, 期間有一兩次咁岩我返左香港佢攞去原廠換油, 佢話換完冇咁爽喎 (不過烈市honda都係有賣motul, 入左d咩我就唔知啦), 佢地交換車渣左一個圈, 之後一個黑面一個好開心; 開心果個梗係覺得保養得好值得, 而家仲渣緊! 唔開心果個三個月後換左車lu, 因為compression reading都有d分別啦, 一架d嘩佬明顯響d要較咁囉 (其實我都真係好唔好意思, 攪到佢心裡面有條刺, 不過都好既, 佢真係好鍚車, 只不過係之前唔識)
係, 塞車咁冇冷空氣打入去咁個cooling system就梗係會用得勁d (夏天開埋冷氣可以overheat tim), 不過唔代表你cruise hwy就唔熱, 架車愈行愈"Lup", 停一停, 歇一歇再行, 又爽番...
Of course engine will get hot, but how hot is the question. Your engine is way hotter when you're stuck in traffic than cruising on hwy. That's why if you drive in heavy traffic, you should follow the severe service schedule lor.
應該咁講, 唔同既熱啦, 塞車塞得耐, engine熱架車會lup, 一行番順又會好d; 行長程既其實個engine都好熱, 所以其實一樣咁重要...
不過我覺得如果一架車成日行短程(每日都係行十零廿公里之內), 同一架車成日行"中程"(每日行四十零五十公里), 咁中程既會好d; 但係有朋友日日行80至120km左右既都有, 我唔見得果d好囉; 好多時候驗二手車其實已經可以睇到好多野, 不過當然, 買得起新車而又換得起身既, 保養好似算唔算唔重要?
咁但係你又冇講點叫密, 點叫唔密? 有d人覺得六千換油太密, 有d人又覺得六千太耐, 你既建議係?
I recommend following the manufacturer's schedule. Make sure you know if you're severe service or normal service. That's the key. If you're a taxi driver and you follow the normal schedule no doubt you will trash your engine. If you ask me how long, I will say what is your driving condition first.
umm...咁我諗你既車都係跟廠建議去做? 行左幾多呀? 不如我搵架同年同款既攞黎做個compression check, 比較下post上黎再討論下丫; 你帶埋油同油隔黎大家fresh oil比較下亦得...當係送比其他老友記既禮物? (唔緊要, 你可以自己落手落腳做, 或者做完先即刻黎都得)
我都係想比較下ja...好似琴日一個朋友架車咁, 二手番黎試過engine flush, 換多幾次油之後又回復原狀, 咁我上次就叫佢換完油行左1500km左右番黎試下放出黎咩樣(佢行左1415km), 睇落似四千零公里囉; 入左落去既新油明顯比上次入落去既好左, 今次二千再番過黎...
換完之後同佢出去食飯走hwy落烈治文, 架車順左好多...咁又點解呢? 冇理油呢d天氣行左千零公里就有分別架喎? 咁唔理佢照舊五千換, 佢又好似一次差過一次, 咁點算呢???
人生真係太多問號喇, 好彩有shutterbug...下次我可以copy and paste話番比人知 (不過我亦都知當中其實佢地已經係度CD Rom緊, oooops).... |
