In an automatic car,i dare say u won't feel difference between VPower 97 and VPower Racing...maybe smoother mid range,that's all...


But in tuned up manuals with a good set of clutch,the difference is there...that was my experience...
What kind of difference are we talking of? Btw, my car is a manual...

Difference is the engine does feel lighter at the crank...but whether ur gearbox is able to transfer the difference is a totally different matter...U have to make sure other things like whether ur Head Gasket is leaking or not,or Spark Plugs in good condition...but light could also mean less torque,hehehe...for me,it help me get to higher revs quicker when turbo kicks in

I take my plugs out for carbon cleaning every 3days....so it really depends on your car's condition also...

But as for FC,i feel that it does drink much quicker with VPOWER RACING than other types of fuel...And whether it is worth it,it is up to you to decide....DAMN Expensive using VPOWER RACING (my thought)

Well to be fair, there wasn't a long interval between me using regular 97 and the Vpower Racing. If indeed my plug is in bad condition or any other problems, I would've noticed it even when I'm using the regular 97 but that's not the case.

What car u driving mate???
Anyway,Difference is minor only...if RM3.2/LITER can make addition 15% to 20% increase, Kakimotor/JC Racing/N1 all bankrupt liaw loh

Honda DC2..Yeah, I figured the difference would be minor. Just curious as to why it feels as though it is inferior to regular VPower. FC seems the same though..didn't really check seriously so could be wrong.

DC2? Car already fast,still want more ahh??? Hahaha...have to go serious stuff like Hi Cam and all loh with standalone....that's the only way you will feel more power in your case

From my personal experience, the difference between RON95 and RON97 is very noticeable.
A 18.5L RON97-46.5L RON95 mix yielded 22% better FC then solely RON95 on 270km long distance test. Smoother engine and response is obvious.

I usually pump at Manjalara Shell, today I pump at Mont Kiara since on the way to work...
Seems engine much quiet now. Tak ada tak tak tak sound, will try pump again at Manjalara
next time...see if is the same...:driver:
hahaha I usually pump at Manjalara Petronas. So far so good.

I gatal gatal went to pump RM50 BHP dat day...not bad and quite smooth as well. Still unsure on the consumption yet as still got half tank to go
Both of u so near to me. If u guys like Petronas, go Bandar Sri Damansara.
New station, feels nice. :D
Manjalara Petronas so tight. :rofl:

No longer going for Shell now :rofl:
I'm going for Petron/Esso/Mobil.

Car is more responsive and smooth. In terms of responds is better.
But then in terms of good FC, still Shell was better.

Really? I've never had any decent performance or FC figures with Shell

Still testing though but seems more responsive with Petron rather than Shell. But FC
seems to be more, but still testing, have yet to be able to confirm.

Maybe could be just psychology wise

No need to step much and the car seems to be fun to drive than usual but petrol drop
faster than usual when pump shell. I have to do mileage count to get an answer.

tested the diff with my ex-kelisa when RON95 first came out...

with RON97... i get about 80km more per tank... and the diff was only about RM10 per full tank at the time...engine felt lighter too...

test was done using the same brand taken at the same station for both RONs...



n my wife currently drives a kenari... she also says shell has the worst fc among all...

RON 97 increase price by 20cents!
Dafuq? Straightaway after election?

Coooonnnnnnneeeeeddddddd
But last time also already reach that price what. :)

Ron95 + ron97 = ron96?
If 50/50 mix.

Whoa really that much difference?? On a Kelisa some more? That difference translate to how many km/ltr extra then?

caltex - the best.. :top:
Does Caltex offer loyalty card program like Petron/Esso?

Then what about the link? :hmmmm:
Ah! mentioned there March 7....

"The retail price of RON 97 petrol will be RM2.90 per litre effective tomorrow, March 7. This is a 20 sen increase from the existing RM2.70 per litre."

Old news.....

i dont think there is any difference between them as they are same and work in same manner
You mean RON95 and RON97 or between brands? If you're talking octane, then you're not quite right. Different ignition times makes a huge difference for a high compression car but you're right that they work the same, ie - they're sprayed in, it ignites and it gives the car power.

Yup, higher compression engine won't be able to run well on Ron 95....:banghead:

Depends on the state of tune though. If the engine tuning allows to use lower RON then still ok. Might not make the most max power or as fuel efficient but can still run fine as long as there's no knocking. Direct injection engines also can run with RON95 despite the very high compression.

No point if get lost of power, right?:biggrin:

Well lost just a few HP does not mean the engine cannot run well. Most probably the loss also more at the mid-upper range of the rpm so would not be that noticeable anyway during everyday normal driving. Of course this is mostly for normal every day car. If high performance cars with more aggressive tuning and especially FI engines then they would be more sensitive and might suffer more power loss or may indeed get damaged due to knocking. But if no knocking, then should still be ok.

Yup, mine knock at 4 to 4.5k rpm, until I added some additives to run RON95...

No surprise la, your car is high powered turbo monster la, cannot drink cheap stuff. :biggrin:
Have to detuned the ignition and boost a little bit maybe. My car can still tolerate the cheap stuff cause still normal level car. :biggrin:

True, but less aggressive tuning would render the higher compression nature of the engine useless. Might as well not bothering with high comp in the first place.

Direct injection is a different story though. The very nature of the concept means knocking is less of a problem when using lower Ron fuel with high comp engines. Wonders of (relatively :biggrin:) new technology!

Yeah, I'm also now starting to learn about this GDi engine, cause this is the first time I own one. I do hope it will serve me well and not make me regret buying one!

The cons of GDi engine have started. Dirty inlet valves, since fuel is injected directly into combustion chamber the inlet valves are not cleaned by the fuel.
In the older technology engine where the fuel is injected into the inlet manifold just before the valves, this will clean the valves...
Everything got pros and cons....

As mentioned by bro. pwhyze, if want to detune might as well use NA. Mine is already standard low boost, if lower some more then also no point.....:biggrin:

Yeah, GDI engines need to decarbonize more often I suppose. I've done it once a few weeks ago, pretty dirty.
