V-Power is Crap or Not ?
Posted 19 April 2005 - 12:04 AM
spikes off after the white patch in the dashboard gauge. But recently it
developed a slight vibration (or very fine clanging sound). I asked
around in the foreign forum and most people say it's detonation, so I
thought maybe V-Power is a better option. Waited till the the alarm lamp
came on permanently and off I went to fill her up with the blue petrol.
Just coming out of the station with the pedal down, I felt that the car
just doesn't peak like it used to. The boost does not go over the white
patch and no pinging sound. So did I solve the vibration noise ??? I
repeated the whole process several times and it's the same. I don't see
the needle touching redline and the autobox upshifts at 5200 revs but no
jerks or anything wild.
One theory that came to mind is that with a higher octane level (which is
recommended by RICA), the performance of the chip is better, and because
we relied too much on butt dynos, we feel that the lurching and jumping
is good but the ECU knows better. As soon as peak power & torque is
detected, the ECU tells the b/box to upshifts at optimum range. So that's
my self-consulation or consultation.
Question : Do you have any negative feedback on the V-Power ? Kenari1
says Mobil/Esso is more superior. I will try that the next tank but there
goes my Bonuslink.

after being fed with vpower... really, i can feel it... more pickup,
engine runs smoother.. everything just looks like as being very ideal...
the most obvious point is that after having vpower inside the tank, the
pickup was great, as if u are driving small cars je.... uhuhuhuuh...

difference. Wallet injury - a lot of difference. Back to normal shell now.

no difference between the blue & regular petrol except price. octane
rating is pretty much the same for all regular pump gas you'll get in
this country. i personally think v-power is a massive rip-off.
stuff i've tried, and works - octane boosters. you'll immediately notice
the difference, especially on a hot day. try loading the car on high
gears at low rpm uphill climbs you'll know what i'm talking about. stuff
that i've tried & found to work well include afterburn & maxima. engine
feels creamier, smoother, subjectively more powerful & best of all - no
knocking. a bottle of the stuff will set you back around 17-20 bucks
depending on where you get it & it's normally recommended to put in a 1/2
bottle of around 250ml to a tankful. probably works out cheaper than
getting a full tank of v-power anyway.

performance but I'm not into power. So, have gone back to the regular
petrol which is lighter on the pocket. The wifey says that Petronas petrol
is better but I'm a lifelong Shell user. To each his own. The choice

Mobil/Caltex/Projet - good fuels, with the butt dyno giving you the best
result. what i found is caltex doesn't ping, but mobil does. but both gives
great oomph in acceleration.
Petronas - Makes the engine rev higher into rpm range but sorely lack in
Shell - whatever their marketing strategy is, the petrol sucks. if you're
into this petrol for bonuslink points then by all means stay with it, but
otherwise stay away from it until someone somewhere can eventually say -
yes, they have inproved.
But again that is what butt dyno can only tell. put the car on a real dyno
then you will see the differences.
my experience with v-power - with tank empty i went to one station."sori
lah tak ada lagi. cuba lagi ya." another time, another station - "stock
masih tak sampai lah.". so that was the end of my ever wanting to try the

after that, i stick with petronas. for the sole reason it's on my way
to/from work! i guess there are differences, but not that material it
fails to get me worry about the engine performance.

engine can operate efficiently on fuels of a wider range of octane
rating, but there remains an optimum octane for the engine under specific
driving conditions. Older cars without such systems are more restricted
in their choice of fuel, as the engine can not automatically adjust to
accommodate lower octane fuel. Because knock is so destructive, owners of
older cars must use fuel that will not knock under the most demanding
conditions they encounter, and must continue to use that fuel, even if
they only occasionally require the octane.
If you are already using the proper octane fuel, you will not obtain more
power from higher octane fuels. The engine will be already operating at
optimum settings, and a higher octane should have no effect on the
management system. Your driveability and fuel economy will remain the
same. The higher octane fuel costs more, so you are just throwing money
If you are already using a fuel with an octane rating slightly below the
optimum, then using a higher octane fuel will cause the engine management
system to move to the optimum settings, possibly resulting in both
increased power and improved fuel economy.
Once you have identified the fuel that keeps the engine at optimum
settings, there is no advantage in moving to an even higher octane fuel.
The manufacturer's recommendation is conservative, so you may be able to
carefully reduce the fuel octane. The penalty for getting it badly wrong,
and not realising that you have, could be expensive engine damage.
Regarding the Octane Booster for engine equipped with CAT:
Catalysts in CAT also inhibit the selection of gasoline octane-improving
(octane booster) and cleanliness additives (such as MMT and phosphorus-
containing additives) that may result in refractory compounds known to
physically coat the catalyst, hence reducing available catalyst and thus
