let him be the lab rat first. hehehe..... per battery advisory, the battery replacement should be same type whenever we perform replacement. As bezza advance's alternator is slightly different (It is evident when you look at the alternator model number on bezza X vs Bezza advance).

If bezza advance is just simply put in eco idle start stop function without any other high end stuff (like the alternator), then we should be safe to use normal NS40 battery as well. that is the theory though

let the rat race began.

Guy, i using petron 97 for bezza 1.3x. Fuel consumption show 16km/h. Total full tank can last for around 480km ( Still have last bar). Driving 80% highway, 20% city. Do anyone have similar fuel consumption? I believe it is a freaking incredible fuel saver car where my previous avanza need to pump in rm80 for full tank while bezza only around rm70 for same travel distance and working day.

some say shell 95 also not bad. the very first tank i fill up for my car is shell 95. i travelled 80% highway 10% federal road 10% city drive. and the onboard computer returns 18.3km/l, and my car is fully loaded 4 adults 1 toddler. boot is equally fully loaded as well. tyre pressure is 250kpa per factory recommendation.

i don't have chance yet to have another highway run, if i do it again then i will evaluate it again as well.

petron ron95 bezzaX, 16.5-17km/l, 80%highway too.

My opinion of higher Ron feuls are better suited for start stop drives, ie town, or top speed runs on the race track.
And the turbo engines make best use of these kind of feuls.

On a highway, with constant velocity, a lower Ron fuel will do just as well.

My last run on just Hyway at 110kmh 1 person, 20 kmL.

3 adults, 50% Hyway, 50 % trunk/ B roads,
18.5 kmL.

All on Ron 95

RM 30 with 0% GST, but usually no stock at service centre, they will order for u from HQ

i pump the tyre pressure at 220kpa front and 210 kpa rear. Feel comfortable when passed the bump, pot hole, bridge joint and uneven road. Try to get a bonuslink card before try shell.

I feel petron 95 give slower response when i want to take over. But, it is true that price of 95 and 97 is huge differences.

Ya..
That's why I said that higher Ron is better for start stop traffic.
The higher combustability of high Ron fuel makes the engine more 'eager' to move..

Once on Hyway, and just cruising, u won't feel the difference, and higher Ron higher combustion does not come into play unless u are racing on the Hyway,

So for long distance cruising, save urself some money and just use Ron 95.
Unless money is no object la.. Heh.
Below is a test done by Paul tan.

hmmmmm... link removed... anyway
anyway, google: ""RON 95 vs RON 97 fuel test - which one should you use? - Paul Tan""


There's also a test done on 'fifth gear' TV show, Mabbe u can find it on utube, where they test performance on a dynometer..
That's where they discovered where turbo cars benefit more from higher Ron fuels.
here... found it.

or google: 5th Gear - High Octane Fuels, if link is removed...

Be advised, higher Ron also makes ur engine run hotter.

From my understanding, higher ron is for higher compression ratio engine to avoid knocking. So it would makes sense to me that turbo engine require it as they take in more air.
Thats why high performance car has higher ron requirement.

RON 97 for me would travel more distant with more power, if calculate by distant per price, it would come out same with RON 95.
That was before when RON95 & RON97 has weekly fluatuating
Prices. Now the RON95 price is fixed it would be much more cheaper driving RON95.

But i always thought RON97 should run engine colder, this i really need to do more reasearch.

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.

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

I could Always be wrong..
An all knowing omni being I am not..
Lol
Please correct me if I'm wrong..
Will love to correct my mistake and any misconceptions I may have..
And I'll thank u for it too!
Your humble servant..
Jtan

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.

Sarcastic noted.😒
I just meant that i always thought it should run colder with RON97 and i should do more research.
Im not disagreeing with you.😑

I've been putting ron97 nowadays on my gxtra and notice a better acceleration,0-100km way faster and travel further.ron95 made the car sluggish and it tend to downshift quite often.what about others opinion?

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

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...

Other than how u feel about the fuel type response from your car, a quantifiable way is the milage you get from the various fuels.
How you feel is subjective, but also important.. Don't get me wrong..
But the pure numbers in this equation, imo, is the science of the subject. The numbers is quantifiable.

Then the answer to the equation of kmL for the different fuels involved can be answered and much thanks from me especially since I've yet to use ron 97 for this car..
Then we can convert KM = RM..

Add the kmL and how u feel about the driving characteristics of Ron 97 will determine if its worthwhile to pay more compared to the returns.

My2sen

Will try 97 in my next full tank.
I'm now very curious.. Lol
Let's me see how.. Heh
