I understand that in the US they don’t use the term RON( Research Octane Number) such as in Europe and Malaysia, but instead they simply use 91 octane fuel or 93 octane fuel. So if the owners manual states “minimum 91 octane” does that mean the engine is rated for RON 91 and upwards?
This is the kind of good quality content/video we should have, good job Kon hope you get more viewer on this type of video come to think about it i dont see others doing this kind of video in Malaysia. good job again .
I am using honda civic 1.5 turbo . On ron 95 ,the fuel consumption is balance of power and performance. On Ron 97 , performance is up by 5 percent maybe(not so noticable) and waste of money .On Ron 100 , fuel saving is highest and performance is as normal too( i felt i maybe able to cover petrol price with the fuel saving ) ,however too much of smell comes at cold start . I havent try shell ron 99 performance because my tuner says shell losses its power due to imbalanced octane character since he has been custom tuning for a decade or so . Oh yeah,im stage 1 tuned @ 185hp and 285N.m
Most mainstream engines have to be able to take RON 95 in order to satisfy the mass market. They may or may not be at their best with RON 95, but they should be able to run RON 95 without problems. In some markets, RON 95 is premium fuel!
@@1992vinod in US their 95 is equal to Ron 99 because their octane system is different. They are using PON (Pump Octane Number) their PON 91 same as Ron 95.
Ada keadaan nak benefit ron97 I mostly felt during low-mid throttle conditions. And it is consistent on 2 of my old bmw. Technically, low volume charge (part throttle) needs very advanced ignition timing(low volume-slow flame propagation). Thus higher ron allows it and makes better power Except on general cars, like family's kenari, ron97 doesnt make any difference. I once wanted to try 1 month of ron95 on my old 36..intended to see how much saving i may benefit. Menyesal after the first fill up ha ha ! Even driving slow require a lot of throttle..dahla pedal minyak dia berat
My 520i shows noticeable difference when I fuel RON 97 vs RON 95, as does my S-Max. So now, all my cars on RON 97. Even my Waja used RON 97 back then. Haha.
Mazda says the engine will run on RON 95 without problems, and they had in fact tuned the engine to accept as low as RON 91 or 92 for our market, but I would think that given the 14:1 compression ratio, there is bound to be some benefits with higher octane.
I had drove 1.8 prius for more than 10yrs. I had tested RON95 vs 97 multiple time for years. Endup require to stick 97. Why? Carbon built of RON 95 lead to prone of error code lighted up. Pumped 97 again, O2 sensor error code dissappeared again. Newer engine doesn't significantly prove vast different but when engine start aging with high mileage, the petrol price difference is far cheaper than overhaul.
You are right on engine age having an effect on knocking. With mileage, the engine builds up carbon deposits on the cylinder wall, which has the effect of 'increasing' the compression in the combustion chamber thereby increasing the tendency to knock. What is the advised fuel stated in the manual.
Yup Kon, Wise of using ideal RON based on engine condition and future repairing cost shall put into consideration. Unless giving up ownership once the car start to throw some tantrum. 😄
I can’t speak for cars, but for bikes, specifically the Yamaha R3; pumping 98 long term has caused more carbon deposits in the exhaust valves and in the manifold due to the engine being not able to burn the additives that gives the fuel a higher flash point and it generates less power as it doesn’t burns as cleanly. RON91 on the other hand (was in Aus) gave the most power with stock engine mapping, dyno proven
@@darrenfoo8269 yup, i had no idea on how the bike engine work, will it be sophiscated mechanism such as NOX sensor (as KON did mentioned) or maybe something else that help to auto calibrate ignition timing having conflict based on manufacturer setting ? Happy for you to find out what defer your bike reliability issue. Regardless which RON you using, keep you smiling enjoy the ride will the best. 😄
Bmw m54 2.5 user, ron97 performance and fc benefits just too minimal for the price differences. I mean even 3hp increment is too little to notice for a 180~190hp motor
It sure makes hell lot of difference on my Beemer. 95 just cannot get get the car to shoot .It just drag along.Real shitty experience. For my 1.5 Toyota daily runner it was not much of a difference. have no issue with it.
My car (and others too i suppose) is an old car,carb toyota corolla, and still,without advance retard,and i dont think cars can change compression ratio..why i(or we) can still feel the change in term of performance eventhough by a bit, when we pumped 97? Maybe 50/50 placebo effect and actual difference in driving I read someone commented that what we felt is because of 97 cleaning the carbon buildup, but that's 50/50 for me
@@KonWaiLuen you are always overly concern about technicalities as oppose to actual benefits from the point of view of the viewer. My assisted word processing typo being a perfect example.

using ron97 giving u the best driving experience ever, trust me. u will never ever wanna change after that.
yep! a little expensive but worth every cents. I've changed from ron95 to vpower97 and never changed ever since. my engine improves a lot.

Hi Kon, thanks for sharing, perhaps next to make comparisons between semi-synthetic vs fully-synthetic oil, any difference?
Thanks & stay safe...
Great suggestion! Let me read up.
Hi Kon, thanks for a detailed explanation, much appreciated.
btw, which fuel rating would you recommend for the B48 engine for normal city use ?
G20 here. Im using Ron97

Since RON 95 now Euro 4, I’ve been using RON 95 most of the time. My Accord can accommodate RON 91 minimum.
