i'm driving myvi. last time i use shell 95...makan minyak because of no power. city driving making me going lower mileage, but driving highway is good.

so i change to primax 95 petronas. increase mileage in city drive because of greater power. but abit noisy.

then i chg to BP with the latest fuel. engine more quiet and as great power like primax.

will try to test primax xtra for a month and post feedback later.

i dun wan try 95xtra, prefer go for BHP2X95...got contest of winning cash n inspira....

Filled RM20 last sunday and felt my engine more responsive(Tried normal Pimax 95 before,better response but lower millage).Filled another RM20 today.Was using Shell 95,got better millage but response not as good as this Primax Xtra in terms of performance.

Shell 95 - 12.xL/100KM
Primax 95 Xtra - 11.0L/100KM

After this will pump in full tank and watch the millage carefully.

so far primax95 xtra improved a lot from the previous one , it feels like ron97 to me , more power and smooth ( use it on toyota camry 2.4v )

engine sounds quieter with this... but performance and FC looks bad.

IMO, all petrol the same when u talk about same octane rating (except maybe VPOWER)...even if you feel you got more power or better mileage, it's all uncontrolled tests...agak-agak only....that's why some people claim better FC, some worst, some more power, some no power....Some people wanna test new fuel...tekan kuat kuat...feels more power...but FC no good...some wanna test mileage...light foot...got extra mileage, but no power....so back to square 1.

I vote for BHP due to Inspira contest.

Pump-ed this RON95 extra lasts sunday... FC looks the same only...no significant improvement... Driving style maintain...sometime tekan, sometime sentuh...

My own rule of thumb when calculating FC after a brand switch is to ignore the FC and "power" feel for the first two full tank sessions as it is the transition period where you need to purge/dilute the tank from previous brand's additive mix.

And calculation needs to be on a full tank basis (i.e. volume pumped to reach full tank after driving xxx kilometers) rather than distance covered on a partial refuel.

That is basically how I compile my FC trend.

but when u empty the tank....there are chance air masuk ur engine through petrol tank.....there's risk of damaging it...nt a good choice 2 do it....either left 1 or 2 litres of fuel in it than empty it....my old SEG kena overhaul engine coz i really leave the car tank empty b4 i pump....for 6 times, everytime push the car to petrol station and ppl start laughing at me ><

i just fill up RM50 of the primax 95 Xtra on friday
got like 10 liters of esso left (the reserve)
the noise....quite good...not as loud like primax 95 be4...comparable to esso
and what i found out is that it doesn't struggle to go up over 90KM/H
so that is comparable to RON97
usually RON95 struggle to go over 90KM/H...i can hear the sound of the engine working very hard to go up
only RON97 makes the engine very relax even after 100KM/H
next thing want to monitor is the FC cuz previously petronas for me ...the FC is like drinking water...it drains very fast
overall for now...petronas jumps from last place to second place for me...esso still no.1 although it also struggles on high speed

car is saga blm

It is not necessary to empty out the tank. I always top up my tank when the gauge meter shows 1/4 tank remaining. That means I need to top up around 31 or 32 liters (tank capacity is 42 liters). What I need is to sufficiently dilute the previous brand enough before taking records (and I usually take a 5 readings average instead of just 1 reading so that there will be further dilution as well as averaging out any variables that happens during my drive).

Really? I find Esso gives more power than BHP. Not sure where Shell ranks yet in terms of power and FC until I start taking measurements.

Each to his own and maybe depending on the car. For me, Esso gives good acceleration compared to BHP when climbing uphill on a small slope outside the area where I live (go through there every morning on my way to work). Interested in testing out Primax but have to finish my current Esso run first (expected to end around June/July'11) before switching.

Seems that you have not been reading my sentences correctly.

So far for me BHP the best.. very different compare to shell 95.

Dude...there's a difference betweeen



versus



Has the interpretation "I will be refilling using Esso brand for the next two months" ever occurred to you?

filled up Hyundai Getz full tank Primax95 Xxtra, got 2-3litres old Primax95 left. that was last week. Been driving around for a while, seems like no noticeable difference in terms of performance. not sure about FC though.

Used the fuel but doesn't notice any significant improvement in mileage and power delivery. Perhaps not the right fuel for my car.
