Lol.
Not being sarcastic at all, but acknowledge my info and views may not always be right...
I'm only human..
I now have to face in my life that my son and daughter can prove me wrong.
(and I'm actually feeling proud that they can do better than me!)
And I insist that they prove me wrong rather than give me face..
Really, not being sarcastic to u..
My apologies if I came across that way...

Ow... Sorry about that.
I dont get used to see honest humble comment in forum.
Its my wrong for misinterpreted your comment, no apologies needed and my apology for harsh tone.

usually you get more active ingredients in RON97 fuel compared to RON95 fuel, and nowadays our RON97 are Euro4 standard which is lesser sulphur content. though it doesn't direct related to performance but it is linked to emission and probably some characteristics in terms of engine performance.

and yeah, higher compression engine requires higher ron fuel, bezza CR is 11.5 which is pretty higher for a port injection NA engine. even serena hybrid DI engine is doing 11.2 CR. Bezza engine surely tuned for RON95, i do believe it should be perform better with RON97 (like you seen on Honda Insight, tuned for RON95, performs better with RON97), as you get lesser chance of knocking. And i personally think that the "higher RON fuel = hotter engine" is somewhat related to the anti knocking characteristic, when an engine lesser knocking, the engine timing can be optimized to achieve their ideal timing hence more power, conservation of energy tells you that when you get more power from your engine, meaning the combustion is stronger hence it is hotter, given the fact that our engine is around 35% thermal efficiency, imagine 65% of poer goes to heat, will that make engine hotter? i think the answer would be a yes.

If the extra mileage gain from RON97 able to cover the deficit of price then it surely a good deal.

Since you are replying to my post.
I dont really understand your question.

Any good deal for 1.3 x premium auto? What rate you guys get? I have colleague interested lol

Correct me if im,i think that going for a higher octane fuel will lessen the wear and tear of an engine meaning the engine will last a lot longer before needing a overhaul or in rare cases new engine..because the fuel has more of that 'oomph'..well you pay what you get..paying alot in a long run or paying slightly less in a long run

Eh sorry wrong thread response.lag of sleep.

In theory yes, higher RON will have a cleaner engine.
But not so sure if its really matter in the end.
For example, i had a 12years 1st Gen MYVI before trade in for Bezza.
Its was running smooth with RON95 (or RON97 before introduction of RON95) all the time without any engine breakdown, of course all the maintenance (8k engine oil change, semi synthetic oil) must be done regularly.

I would not say the same for this engine, since the CR is different. But i do hope it will still run fine for 15years on RON95.
No problem bro, i just thought could i have said something wrong.

You got a good point there... Didnt know 11.5 CR was consider high for RON95...
If thats the case then it would means that the engine is tuning down fuel mixture to avoid knocking. So RON97 should get the full performance of this engine.

I have never tried RON97 since i own the car... Will try few tanks later and compare a bit.

book on june 9, car loan already sign . until now still waiting. WTH Perodua

whats the reason from sales advisor?

I do agree with singk here. Higher RON pretty sure come with better active ingredient but differences between 95 and 97 with not be reflect on daily usage performance (immediate effect). It affect on environment emission standard, engine cleanliness, motorcyclist surround inhale hazard and etc in a long term effect.

But, in the situation mileage vs ringgit, i think all 95 fuel have it own advantage due to fixed price in current admission of new government. In my working day driving case, 70km per day, 6 working day. 66 ringgit of petron 97 with around 25 litre on every wednesday night. Car is only one month years old, need further testing for petron 95 in up coming september.

Btw, lowyat is a harmony forum. Hope all didnt end up like cody and songsen.

Hi, i hope someone can help test answer the question.

So my sister decided to manually lock the doors while inside the car and left the keys inside while leaving the passanger door(right beside the driver's side) open. Door then slammed partially and cant be opened.

If we push the door in, does the locking machinism unlock like older cars do?

Thank you in advance.

i believe its a yes, partially closed then pushed to fully close is no different than closing normally   

9 june - pay deposit, SA said will get car within 2 weeks.
20 june - loan approved. SA said wait HQ allocation., alot people will slow.
5 July - Still waiting Hq allocation.
21 July - SA said queue at No.3, very soon can get.
3 Aug - SA said queue at No.1.
14 Aug - still queue at No.1.
23 Aug - SA said Perodua factory always shut down, HQ working back on 24

Thank you. Just as an update. The doors will auto unlock, ONLY IF your keys are inside. Without keys, it will just stay locked.
At least you'll get a car. Now, no car almost everywhere. Myvi lagi power, production line shut down.

The problem is SA haven provide invoice yet, BUT said invoice will incur SST in Sept. Mean while my friend book at another outlet slower than me already got her MYVI on early AUG.
