Higher RON = More Power?

[Zxcvb]

If I drink 100plus everyday, will I run faster??

 

i eat $3 cai png for daily lunch at work - dats my minimum requirement. Do I have to splurge on $15 meal thai express everyday?? No right??

 

The point here is, is it worth to pay more?? Depending on your car, get the minimum is good enuff. No, your engine won't spoil. Singaporeans may be well-informed, but they are most gullible onto hype and advertising.

I only heard turbo car need higher RON petrol...

98 petrol is for car with high compression engine....to prevent 'pinging'.

r u seriously fking kidding me ? u guys still pump 91/92 ? want ur engine die sooner go ahead . in nowadays car all recommended is 95 . higher performance cars like turbo n v8 uses 97/98 . seriously u guys got to be joking me . YES someone mention retardation of ignition timing auto self adjust system . that is true . tat is why the car will feel sluggish , not to mention knock too . walau please loh . 91 ron realli sad case lei . dirty the engine n no power some more . u tink u guys living in 3rd world country where they have no choice but to use lower octane ar . omg use common sense a bit .

 

since someone mention a blind test . i dare to take on the bet . 1 full tank . lai come bet wif mi . there is a difference plz .

 

Dude, if u dunno anything, dun act like an expert. You are only making a fool out of yourself. Since when nowadays car all recommended is 95??

driving a vios, recommended is 91 and above and i have been using 92 for past 8 years. engine is still good and dont have the sluggish feel. I think you need to accept that it's not a joke

are you driving auto vios ? if you drive manual vios, the 92 and 98 definitely make big difference when you suddenly floor the accelerator.

However for the best response, dont use shell fuel economy 98 or spc 98. for auto, the difference may not obvious due to the AT torque converter will spool first when you floor it.

the 'better' performance for higher RON is due to the additive used?

driven nissan sunny b13 past its 10th year on 92. no problem whatsoever.

92 is dirty fuel? i did not recall the car getting choked?

 

those in 3rd world countries are likely detuned already. that's why they can use 91 without problems.

similarly for some jdm cars from japan. they have 100. if we import them here, we got to either tune the engine or use a booster.

 

important is to avoid using the rating lower than recommended by the manufacturer.

go read up a bit bro.

[Watwheels]

I think some of you need to read more about RON rating and its usage. Tigershark is right about the fact that the higher the RON rating is to prevent engine knocking for engines with higher compression ratio.

 

For engines with higher compression ratio, whether it's NA, TC or SC, chances of fuel to self ignite before the spark plug releases a charge is higher. Hence I think petrol makers add chemicals(or some of you like to call it additives) to prevent the fuel from self igniting(which will cause engine knocking) to so call making it less volatile for higher compression usage. Thus the higher RON rating.

 

Ppl tend to think RON92 or lower is the fuel that is "diluted" petrol and is added with minerals that will dirty or damage the engine. It's apparently not but the ones with higher RON rating actually are added with more "impurities" to prevent engine knocking. Most Japanese cars have recommended RON91 or RON92 ratings, there's no need to waste money on higher RON ratings. Adding additives to petrol IMO is also a waste of money that does not give any performance if your car's recommended RON rating is only RON92 or 95 but you risk damaging the engine by adding these impurities into the petrol.

98 or higher is really good ----- for Petrol pump owners!

 

For cars, just follow the manual, that is enough.

bro .. i know someone driving a 355 ... thats a V8. he always pump SPC 95 only ... he is on his second round of COE ... never heard of engine problem before...

 

but of course, everyone is different. i'm following manufacturer spec and pumping only 98 in my car ...

Yep. Please listen to him instead of your car manuals that was written by the Engineers who designed the engines. Who are the engineers and car designers compared to him in terms of technical knowledge!

[Royho1979]

i tell you the higher ron you pump the better the millage, who's with me?

 

tested on 2 cars, both same effect.

 

i don't travel much and i pump around 300 liters per month.

 

If true, would the improve mileage cover the cost of the more exp fuel?

[Ungtiong]

sure got difference but we will not know what....u can eat oily food and another eat healthy food but the 2 guys can be in perfect health.....but another guy eating oily food can have high cholesterol etc.

 

same as OFC HDMI vs the cheapo version, many INSIST the cheapo is good enough (digital mah, not analog what) , can it is..but there is a reason for OFC version. Is there a difference ..ofcourse!!!! can we tell...probably no.

 

JDM vs Korean? German vs US?

Prius compression ratio 13:1, in the manual, it states avoid using anything more than 92 or risk damaging the engine. I'm rather worried for Msian driving Prius as they don't have RON 92.

 

I think Prius is the answer to dirty fuel and aroma exhaust.

[CH_CO]

just a butt feel and real results from mileage as i track every mileage per pump , i have realised that there is probably around 10-30km difference between each category of ron so cost vs mileage chances are it is quite irrelevant in singapore context , you won't save more than 50 bucks paying the difference unless you pump more than 300 litres per month

first time I come across the notion that higher RON rated fuels may damage the engine.

Do you know that US don't even sell 95? Their norm is only high end of 80.

Me too, when I watch review from youtube, I heard must pump 98 for Prius due to compression, I'm worried, so I went to search for info because I have never pump more than 92 for my current car in Sg. Saw from Prius Manual book state will damage if use more than 92, which also worries me because most of my mileage are done across the bother where they don't have 92.

 

Anyway I believe in Sg, no body care about pumping 92, everyone just have the mentality that 92 is lousy, dirty, sluggish. Just follow the book I say, anything more is a premium.

 

The acceleration from stop is just a small fraction of the drive, most of the time the car will be in cruising stage, what power do they need?
