別的不說，就只談今天凌晨才剛剛實行的RON97汽油起價，就讓許多人民對政府的“英明政策”擁戴不已。不是嗎？起價的是給外國人、有錢人還有駕大車的人打的RON97，又不是我們這些駕國產、低馬力汽車的平民老百姓，既然廣大的人民並沒有收到任何影響，而且又能確保政府津貼油價的人民血汗錢不會花在那些不應得到津貼的人（外國人、有錢人等）身上，這還不是英明政策、還不是體恤人民的政策嗎？
好吧好吧，就當RON95真的不會再起價（注意這個“再”，上次97起價，95不到一個月也跟著起），但只有97起價就真的是利惠人民的天大好事嗎？數據會說話，就把我這幾個月來添加不同汽油並結算其行走哩數的數據來跟大家分享，讓大家知道95與97的分別到底在哪裡吧（以下數據是由我的Kancil所計算，通過不下10次的反复計算所得來）:
1. RON95 Full Tank（正常情況下紅燈添滿缸）= RM35；可行走大約250km = 7.14km/rm
2. RON97 Full Tank（正常情況滿缸，起價前油價RM2.3/litre）= RM42；可行走大約350km = 8.33km/rm或
計算出了以上結果之後，再讓我們看看，一個添95汽油跟另一個添97汽油的駕車人士相比，到底省下了多少%的金錢：
簡單的加減乘除之後就可以的得出以下結果：
RON95比RON97便宜了大約：17.39%
但RON95卻又比RON97少走了大約：14.29%
是的。看了以上答案就可以知道其實RON95並沒有比RON97便宜太多，並沒有到表面價錢上的17.39%之多（40仙）。真正考慮到了汽油的性能（也就是行走哩數）之後，其實RON95只是比RON97便宜或划算了那僅僅的3.1%而已（也就是只有區區的0.71仙），換算成金錢的話，RON95的真正價格其實大約是RM2.229啊！沒錯，每一公升就只是比RON97便宜不到一角錢吧了！
況且不要忘記了，根據市面上傳言，RON95可是會有傷害引擎的可能哦（當然傳言可不可信是見仁見智）！呵呵，所以此文章一開篇就說政府坑人很聰明的原因想必大家都知道了吧？不只可以讓人們心甘情願地打劣等油，而且還可以讓這些人以為自己省下了一大筆金錢！高明啊！
所以說，那些認為油價還可以的朋友，你醒過來了嗎？

my proton makes no difference for RON95 & RON97
Interesting. How did you come to this conclusion?
I tested on mercedes and it gave me about the same distance for both type of gas.
I did this this way:
Pump tank until the nozzle automatically then stop pumping.
Turn mileage meter to zero.
Drive your car whenever you want.
In next pumping, pump full tank again (until the nozzle stop automatically).
Then divide the mileage with the price of the oil that you pumped.
I never calculate all these things, but my myvi is obviously powerless when i'm using ron95, so i rather spend a little bit more for ron97.
Before you make any false assumptions, let us see what the real meaning of RON is.
RON stands for Research Octane Number. Octane number or octane rating refers to the gasoline ability to withstand auto ignition (knocking) inside the engine. Higher octane number refers to higher ability of the oil to fight auto ignition. In other words, it means that RON97 is harder to ignite compared to RON95.
Different vehicles are designed to be use with different octane number of oil. Higher octane number oil is basically designed for high performance vehicles such as sport vehicle and racing vehicle. Why is that so? This is to avoid premature ignition of oil inside the engine because of auto ignition, which happens before the spark plug ignite the fuel. This phenomenon is known as knocking. Knocking is not wanted because it reduces the performance of vehicle.
The right usage of octane number based on design and adjustment of engine will maximize the performance and effectiveness of the vehicle. Modern vehicles are equipped with knock sensor which enables it to adjust its combustion timing automatically according to the oil octane number to avoid knocking or premature ignition of oil.
Not all vehicles require high octane number petrol. You may check your vehicle fuel requirement inside the guide book of your vehicle or you can simply check the minimum Octane Rating at the back of the fuel lid cover of your vehicle. Most cars can still use RON95.
Higher RON number does not means that it is more powerful. It means that it is harder to ignite. It is also cost you more.
Bro, I know what you said, and i read this before. The theory is this, no doubt, can easily find this anywhere in internet, and i did believe that there is no difference between 95 and 97 especially for my small car kancil.
However in reality i found its a big difference there. RON97 actually much more efficient if compare to RON95? Why this happen? I will do calculation for the oil consumption everytime i drive, so what makes this?
Chong: u using shell ron97? it's v power, i think maybe there are some difference for v power. I pump Esso all the while (unless cant find any Esso Petro Station).
阁下是使用一次打油记录来做比较，准确性并不高，特别是在市区行驶，每日的阻塞程度都不同
根据偶对座驾长期的观察，RON９５比RON９７省油３～５％左右，不过缺点是引擎比较吵，力水比较差
ken：閣下的第一句留言就表明了你沒把文章看清楚。我的計算方式並不是“一次”，而是拿出不下十次的計算來做標準，請看清楚這一點。
另外，這不下十次的計算並不是在市區而已，還有我從吉隆坡回鄉時所記錄下來的（去打95，回打97），等油缸亮紅燈了才打。
另外，我的回复已經說了，我計算的方法，就是車子打滿缸直到Nozzle自動停，然後不打。打滿後把哩數歸零，下一次再用同樣方法添油，這樣就可以計算出最比較精確的耗油量了。
我倒是有興趣您的3%到5%是怎麼來的？歡迎你公佈計算方法還有你獲取數據的方式，這是交流的一種，愈多計算方法就越好，也可以集思廣益。
去年９月RON９７被＂提升＂为超级汽油时偶就开始不再打RON９７，只打RON９５，就以前后９次打油记录来计算
RON９７ RM６６３。８０跑５４４５KM，每公升RM１。８０，平均每公升跑１４。７６KM
RON９５ RM６７３。００跑５５８８KM，每公升RM１。８０，平均每公升跑１４。９４KM
RON９５比RON９７省油１。２％，在误差率之内
RON９５稍微省油，每次打油所行驶的里程提高大约７～１０KM
嗯，不過Ron97還是1.8的時候是兩年多前，你確定你的資料和記錄沒有錯？如果肯定的話那就是另一個參考資料，對了，你駕什麼車？每打一次油要打六十多塊，應該是中高檔的車吧？為了更精確計算，建議你每一次打油記錄，把哩數歸零更好。
偶已经说了是去年９月
偶的座驾是省油车VIOS，远比阁下的KANCIL省油
偶从新车到现在每次打油都有做记录，是以里程表来做记录，比每次打油清零来的准确
呵呵，這位仁兄，問一問要多一些參考資料吧了不要那麼激動，又沒有說你錯。小弟我也是每一次打油都有記錄的，錯，是每一筆消費都有記錄，人窮沒辦法。
另外，爭勝心不必那麼強，Kancil不是我發明的，Vios比Kancil省油也不必特別強調，還是你認為駕Vios很光榮？
歡迎大家提供更多的資料，越詳盡越好。
I'm driving Honda Civic 2.0, when RON95 was introduce back then i've tested 2 to 3 times full tank (~40 liter).
My comment for using RON95 was:
1. Less mileage (~80km less)
2. Engine noise
3. Less responsive (need to press gas harder to move the car)
After that I never use RON95 again.
Thanks Momo, another reference for us.
My developer is trying to persuade me to move to .net from
PHP. I have always disliked the idea because
of the expenses. But he's tryiong none the less. I've
been using WordPress on several websites for about a year and am nervous about switching to
another platform. I have heard very good things about blogengine.
net. Is there a way I can transfer all my wordpress
content into it? Any help would be really appreciated!
