Aiya Jason, as long as logistics are involved, cost will go up wan. No matter rural or outskirts. Trust me on this.

Unfortunately the EURO standards are more for emissions control than outright performance. I'm more interested in the additional additives that they have put in for the new fuel but I have yet to check it out.

Added on October 23, 2012, 6:11 pmYes but that has nothing to do with R&D (you terpesong to R&D). It's all economics. Fuel stations will have to build additional holding tanks. Tankers will have to transport more fuel types. Not worth the few cents of savings to the public. Even now, stations serving RON97 is beginning to disappear but I'm sure they have some form of 'agreement' (gun to their head) with the gov that each brand must have XX amount of RON 97.

Therefore, it is not viable to provide RON92 in a subsidised market. Nothing to do with R&D.

I've read somewhere before, probably on Paultan but can't find the article, it said that our fuel stations can have multiple type of fuel at the pumps without any problem or any additional investment. However there would still be some problem in term of keeping enough stock for the type of fuel that is most in demand.

Euro standard is indeed more for emission control but it also dictates a cleaner fuel requirement which will make your engine last longer and able to retain its power output better after a period of time.

why can't just have the ron92 and 95 or ron92 and ron 97 ? as u say ron97 just waste of money ? so take off the ron 97 or just limited it to few station as some car needed ron97 to run ..

Added on October 23, 2012, 9:07 pmso in other word is that mean ron97 cleaner than ron 92/95 which will make ur engine last longer and retain it power ?

So when did some become all? I didn't say ALL cars waste on RON 97. You are the only one who did. It is a waste on most cars that is not tuned to use anything higher than 95. Most is not all. Tell me which country you know that only sells ONE type of fuel that is not under military rule or international sanctions? If you don't understand the economics here, don't bother discussing. This is getting pointless.

Added on October 23, 2012, 9:16 pmAgain, learn to read and understand. We were no longer talking about RON 97. We were talking about EURO 3 BHP RON 95 and RON 97. Nothing said that RON 97 is cleaner and will make engine last longer.

Do not take quotes out of context if you have no idea what we are talking about.

for older car using cis-e injection, the ign timing would restore within seconds after knocking stopped.

I'm running RON 95 for 5 years after engine overhaul now. (Cracked piston) Lets just say that u need to do a few adjustments to milk everything out of RON95 fuel. But i'm running carburetor and i have the luxury of playing around with numbers like O2 machine and such. I believe all ECU can calibrate itself to make use of RON 95. Of course bigger RON number does let u make big HP. But i have always seen in USA those stock drag cars that use RON 91 can make 600hp and when use premium like RON 98 can make 700HP.

So comes to the part that those are high end drag engines. On our engines that usually make 100hp more or less, actually barely noticeable difference. Unless if we could have an engine room, fill one up with 97 and one with 95 and let them idle and see who finishes first. Then do an engine dyno. There will be difference here and there. So whose game?

sleepwalker try to control ur attitude .. if u cannot discuss with ppl dont bother to reply .. everyone here is educated .. isnt' it bhp petrol is euro2m ? or is it the same with euro 3 ?

i just ask why need ron95 and ron 97 why not ron92-ron95 or others .. then u come blast me to read and understand now u are talking about euro 3 bhp .. u sleep talking is it ?

you are the one that seems to be slowpoke.

and you're implying that a well respected LYN STAFF who owns a car you most probably couldn't afford to as uneducated? Look in the mirror bro.

so what if he is mighty lyn staff .. can ban me if u guys want .. can own a good car probably i cannot afford mean he and u can look down at ppl .. and pretend u are educated and better in your life ?? ur way of talking not so educated to me ..

Actually, he already addressed your query quite adequately. Short of physically telling you and addressing what you need to know in person, I don't think there's anything else he can do to answer you online if you don't get what he's saying.

Also, the moderator has never at any point stated anything regarding the car he has or what you have, nor has he talked down to you because of your financial status, that kind of thinking is entirely perceived by you and you alone. So just move on please.

This is what I meant before when I said the ECU will take a few steps back when knocking is detected and will take a step forward at a time after the knocking stops. Then when it detects the knocking again, it will repeat the same process. Just like sleepwalker said, if the engine is not designed to take advantage from high RON fuel, it won't be able to extract more performance from the higher RON fuel.

eh hello pls la. not me who say who better in financial or who drive a better car .. someone else .. did this and say he is someone who very respectfull in lyn and i should listen to what he say ..

leave it be la , there will always be a debate on whether r95 will kill the car engine or not ... sides most car take it without problems ... mine also , but the info i get from the workshops , well , another story .... lol

Can someone shut the conflicted people up and carry on with the discussion? Seeing all this mud slinging in every damn thread is getting goddamn tiring.


I don't know any workshop in KL that has an engine room. However if you're talking about dyno-ing the actual car itself on the differences in performance, I am game.

Caveat - both my cars take at least a day to adjust itself to the petrol for some reason. It's not immediate. So it'll be minimally a 2-day dyno effort.

just like the lady (vicky?) on Topgear said in her comparison on the different RON fuels, it does have a difference, although most average auntie/uncle wont notice it. the engine feels more responsive to the throttle press.

Never thought of it, my car is maintained by the 3S centres, that's actually funny since it has clock over 90K and I don't think I've every signed on any fuel filter change.

Will check on the next service, but I do reckon that our quality of fuel actually causes carbon built up and such, it is recommended to clean the injectors.

Thanks anyway.

100K km is a common fuel filter replacement schedule but some manufacturer's might change it early. At 90k km I can say its pretty much clogged up by then if it has not been changed before.

What bull crap is this?

Those people who says this are obviously lacking knowledge and are picking it out from the sky without any concrete backups.

Same to those who says 5w-30 / 10w-30 oils are meant for Kancil engines.

These are all old mindsets. Wake up!!!!!

Added on October 24, 2012, 4:55 pmMy family cars consists of Pajero, Benz, Civic and Wira have been using Ron92 for more than 10 yrs. Then migrate to Ron95 compulsory by government regulation and joining the pack are two Persona and Kelisa.

No issues at all. No power issues also because these cars are designed to run Ron92 and there is no point pumping in Ron97 because the engine won't perform anymore power than it is designed for.

so what EO does kancil take? what is the recommendation by perodua?

as far as petrol goes, stick with recommendation. if you cant pay ron97 when driving a car requiring it (eg: ferrari/lambo), you probably shouldn't have driven that car in the first place
