Yes, I have tried Petronas Primax, Caltex Techron and BHP only. When the mileage is lower, say between 1,000km to 8,000km, Caltex seems to provide a more powerful acceleration compared to Petronas. BHP is also good but Caltex feels great. The car seems to be less energetic ie. less powerful acceleration, coupled by engine knocking with Petronas. With Caltex and BHP, more powerful acceleration and less knocking.

But know, with the mileage >8,000km, seems like the type of fuel is more or less similar. Little or no more knocking with all types of fuel, even Petronas Primax.

I didn't try RON97 before. Perhaps I will try sometime. Do you pump RON97 everytime, or you just tried RON97 just for several times before switching to RON95?

Yes, I agree that the engine sounds slightly more refined wtih more mileage. My car is about 8,700km now. Still 1,300km to go before the 10,000km service, and I expect the performance from the engine to be better, more refined and smoother acceleration.

I believe, after some time the ECU "learns" the fuel you are using. In my case, after 30,000 km I used 2 full tanks of RON97. Right after fuel up, if feel the car somewhat lethargic (compared to when I 1st tried RON97 at <5000km mileage). The FC is good though. Only about 300 km after refuelling do I feel the RON97 giving better performance.

I guess the ECU needs to "relearn" to advance the ignition timing.

Butt dyno only, no scientific evidence or methodology.

P.S. Drex Chan (EA Autoworks) mentioned that if you install Race Chip, you need to drive at least 50 km for the ECU to take full advantage of it.

I fueled with RON97 when going for my occasional track day competition. The difference is instantaneous and obvious.

When go back to RON95 you can feel that CFE does take advantage of higher RON.

Fo me Knocking can be heard with All RON95 products but less on BHP and Esso.

Knocking on a modern engine?

I have heard knocking on my BOT Persona, my Preve is absent from such sound.

Still no MT Preve owner?
I have had my reservations about the CVT due to the whine etc. but it seems like the 2014 model is even more refined. still looking for non-CFE test drive though :/

just done trip to hat yai and songkhla yesterday.. more than 1300km in less than a week..

Okay thanks for the information. Maybe I will try RON97 sometime, after the 10,000km service.

May I ask where is the place for this "track day competition"? Is it a racing circuit, something like F1?

Okay, will try RON97 sometime just for the fun of it since there are now two experiences that confirm the Preve Turbo to have better performance in engine power and acceleration with RON97.

Can the Race Chip give better FC after install? They claim can get better FC but have my doubts because increase performance normally the FC will go up.

Seems no one on the forum have installed Race Chip or ones that have Race Chip installed at not on this forum.

Racechip claims 1 L/100km savings. Most on facebook say no much difference in FC.

Like that i dun want to install Racechip as i am quite happy with the performance.

Rather use the money to change the noisy tires

Hi Guys,

Had a scary experience yesterday. I went to Section 13 Service Centre to change the one way valve. All things went well when i went to test drive with the technician. Trouble started after i drove off the car from the SC. The car stalled at Jalan Semangat PJ for 30 mins. Then i manage to restart the car and drive and then it stall again in front of Jaya One and then drive again until it stall again at the junction entering the SC.

Malunya....ask the sc what happened, seems got error code at the ABCM.

On another note, change the quarter glass rubber sealant, dunno what happened but the eco tint was peeled off at the top of the quarter at the driver side. SC ask me to claim warranty from eco tint vendor using the warranty card. Is this right? Should claim damages from SC for damaging the tint. It was ok when i sent the car for rectification.

The eco tint vendor sure will ask u what happen until it got peeled off.
If its other human error where can claim warranty one.
Maybe u can ask first and if they say cannot, u ask them to write in a form of letter n den show to SC.
Then u claim tint voucher from SC. If they don want give, buat bising.
shit happens due to human clumsiness and owner have to bare the consequences..how nice.

Ini yang buat saya bengang, think need to speak directly with the service manager already.

how about grounding? anyone here did this grounding thing? some claimed the grounding can increased you FC, as well as the engine performance.

Try make a miniature size of that thing and stuck it on your nose. Can you breath better?

If better go ahead.

OHHHHH HAAAIIII EVERYBODIIIIIIIIIIIIIIIIIIIII
ayammmm backkkkkkkkkkkkkkkkkkkkk!!!!!!!!!!
