[Discussion] Which type of petrol do you pump for Phantom?

[GregTay67]

Just switched from shell 95 to Esso 95. Mileage increased from 34-38km/l

Will stick with Esso 95 now.

[padfoot]

My bike keeps backfiring when I pump V Power or 98. Anyone knows why? In the end, I sticked to 95.

You probably need to retune your carbs.

Last time used to pump Esso98, now switch to Shell95... My bike FC like 16km/litre leh....

[rediscotheque]

used to pump spc95 cos of dbs plus spc card discount.gives me alot of power.speed can go till 120 from kje bke sle then tpe.no problem.after sometime due to increase of price,went jb for shell97 somehow performance drop.maybe bcos of engine oil i used so can withstand the heat.then lower to 95.engine knocking is there too...haiz dunno what to do.

Hey guys, I just bought an FY plate phantom the newer version. Previously, I owned a pulsar for 1yr 2 months and rarely filled petrol in Singapore. Always filled in JB. The 18 ltrs tank comes handy kekekekeke.

 

Now Phantom with 12 ltrs tank no choice got to fill here. I read the manual and its compression ratio is just 9. So I feel RON 92 is more than enough for this bike. If compression ratio was 11 like CBR150 or Yamaha R15 it would need RON 95.

 

So dont waste money on higher RON even though it is few cents more, its still waste, doesn't give any extra power or FC.

 

Just my 2 cents, kekekeke

hi revhappy, after using the 92 for a few weeks, try using esso 95 and reflect how you feel about it here. Just my reccomendation. Cheers.

Hey this was my sharing in the past too (:

I like esso, but due to discount, im on caltex.

Hmm, I feel its tough to make out the difference. If you do make out the difference also, it could be purely psychological. Even stuff like FC. During my 1st top up I got 35 and during 2nd top up of the same RON 92 Esso I got 38. I will keep monitoring few more top ups and then I will know the average FC. After that I will try RON 95 and see if I can feel any difference.

 

There is only Esso near my house and with Citibank Credit card and Smiles card I get 15% discount. I guess thats the best I can get. Anybody gets better discount?

 

Cheers!

I've been cruising 120-130 on my TA150.

 

Tried 92, feels abit rough. But 95/98 makes no difference.

[osxunix]

Will follow my fren go pump in malaysia Shell 95 it was like 50% off compare to SG.

[Allen]

I will never pump Esso 92 again.. My engine knocks like hell..

Can you describe about the knocking? I have been using RON 92 all throughout and dont feel anything amiss. Higher RONs ignite slower and hence give you the feeling that they are smooth.

i recently tried shell95, but didnt like it. still prefer caltex95 or go jb pump esso97.

I'm riding a TA150. Everyday i warm up my bike the sound of idling is like with the choke on. After that i switch to 95/98 my bike do not have the knock sound already.. Not sure it's my bike problem or the petrol but i dare not to use back 92.

Maybe ur block carbon build up liao.. Need to decarbonise.. By right can use Ron92.. Have been using that throughout my ownership on TA150

So does using 92/95/98 any difference for you?

Got this from another forum:

 

High Octane Fuel - Do You Really Need the "Good "Stuff?

 

or:

 

You Really Can Fool Some of the People All of the Time

 

 

"The swami has been hearing a lot of nonsense around the gas pumps these days. People are tanking up with the "good" stuff because the commercials imply that it's better for their engine. When the oil companies use superlatives like "Super", "Extra" and "High"...well it must be better, right? And of course they wouldn't be charging $0.10 - $0.20 more unless they were putting some really good stuff in there, right? Sorry...NOT!

 

"High Octane" is not synonymous with "good" or "better", and does not mean that it is better for your engine! And the chances are pretty good you don’t need high octane fuel in your scooter.

 

High-octane fuels only become necessary when your engine has a high compression ratio. It’s a very long and complicated story…that the swami will make short.

 

First important fact that you must accept:

 

All gasoline, regardless of its’ octane rating, have pretty much the same amount of energy per gallon. What!!! "Sacrilege" you say? Well, actually, some higher-octane fuels have a few LESS percent energy per gallon…so as not to argue over this small point, for the sake of this discussion we will all agree that the automotive gasoline that you buy at the pump, regardless of octane rating, has the same amount of potential energy.

 

Second important fact that you must accept:

 

Octane is NOT a measure of power but of the fuels’ resistance to ignition from heat. A higher-octane fuel, under identical combustion chamber conditions, will burn slower.

 

How can this be? If all of the above is true, how do we get more power out of high octane gasoline? We do, don’t we?

 

Well…yes we do. Here’s how:

 

But first you must understand "heat of compression". There is a 2,000 year old fire starting device that still amazes the swami. A length of bamboo was hollowed out leaving one end capped. A stick, about the same length as the bamboo, was whittled down until it fit snugly into the bamboo cylinder. A bit of dried grass or wood shavings were placed in the bottom of the bamboo cylinder and the snugly fitting stick was violently rammed down the bamboo tube. The heat generated from rapidly compressing the air in the tube was sufficient to ignite the tinder.

 

The same thing can happen in the cylinder of an engine. The piston, quickly squeezing the fuel/air mixture into a small space, can generate enough heat of compression to ignite the fuel well before the spark plug fires, with unpleasant results. If the fuel prematurely ignites while the piston is on its way up, the burning of the fuel, in conjunction with the rising piston, creates even more pressure, resulting in a violent explosion. This explosion is equivalent to hitting the top of the piston with a very large hammer. If you want to be able to see through the top of your piston, ignore those sounds that are usually called: "pre-ignition", "ping" or "engine knock". Trust me on this one; in his reckless youth, using this method, the swami turned a few pistons into paper weights.

 

What we really want is a very rapid burn of the fuel, not an explosion. And we want the burning of the fuel to take place while the piston is in a better position to convert this pressure into productive work, like on its way down. Think of this burning as a very fast "push" on the top of the piston. Despite the violent noises you hear from some exhaust systems, it really is a rapid push on the top of the piston making the crankshaft go around, not explosions.

 

So that we can ignite the fuel at exactly the right time with the spark plug, instead of from the heat of compression, they put stuff into gasoline to keep it from igniting prematurely. The more resistant the fuel is to ignition from the heat of compression, the higher its octane rating.

 

Are you with me so far?

 

Higher compression ratios = higher combustion chamber pressures = higher heat… and it is with these higher combustion chamber temperatures that the magic happens.

 

At higher temperatures the fuel is burned more efficiently. So, while it’s true that the higher-octane fuel does not posses any more energy than low octane fuel, the increased octane allows the extraction of more of the potential energy that has always been there. Conversely, lower compression ration engines utilize a little less of the fuel energy potential (2-4% reduction) but there is also less heat generated in the combustion process.

 

So how do you know if you need high-octane fuel? The swami suggests you look in the owners’ manual! Manufacturers really do want you to get the maximum efficiency out of your engine. They do their best to give a good balance between horsepower and engine life. It’s in their best interests to do so.

 

There is ABSOLUTELY NO BENEFIT to using a higher octane than your engine needs. The only benefit is increased profits to the oil companies that have cleverly convinced some of the public that their new "Super-Duper, Premium-High-Test, Clean-Burning, Used-By-Famous-Racing-Types-All-Around-The-World, Extra-Detergent-Laden-Keep-Your-Pipes-Clean, Extra-High-Octane" fuel is your engines’ best friend. The swami is telling you the truth, don’t listen to that talking cartoon car.

 

The swami hears people insisting that they got better mileage, better acceleration, and less dental plaque by switching to a high-octane fuel. The swami reminds these people that in every pharmacy is a special miracle pill that is often prescribed by doctors, it works wonders because people believe that it works wonders; it’s called a "placebo". The swami warns: never confuse faith with physics!

 

If you are getting pinging or knocking with what should be the correct octane for your engine, start by checking the ignition timing, also check that the spark plug is the correct heat range. For 2-strokes, check for excessive carbon build-up on the top of the piston, the carbon takes up space and increases the compression ratio.

 

If all is well and correct, and you still are getting knocking, then try the next higher octane. You won’t go faster, you won’t go farther, but you will prevent an unsightly hole in your piston.

 

This subject is a whole lot more complicated than the swami wants to bother with. If you are curious to know more, put some of these words into your search engine and enjoy the education:""

The main point is "High-octane fuels only become necessary when your engine has a high compression ratio"

Phantom has a compression ratio that is very low only 9.0:1. That is the lowest I have seen. CBR150 and FZ150i have 11:1 so they would justify RON 95. For Phantom RON92 is more than enough.

Haha.. TA150 has only 6.8:1.. So 92 is more than enough..

Thanks guys for your reply, will try 92 again see if the same problem occurs to me.

[osxunix]

Just sharing my personal experience using V Power.

 

Bike info

Phantom TA200

Age: 10 years

EO: 10/40W

Fuel: Shell 95 (1L/29KM with daily warm up 5min)

 

Try pumping Shell V Power FC only hit 1L/25KM!

Bad experience NO POWER compare to Shell 95 changing lane or over taking slow!

It was smooth but make my Phantom feel soft and the potential energy is not even there

 

[susu]

pump esso or caltex 95. smooth and good power.

[susu]

engine is noisier with shell petrol, no matter 95 or v-power
