I believe i said "fully utilize its capacity". Theoretically speaking,the engine should run at its best using high octane fuel. Again, "theoretically".

However, i run on a RON91 in hatyai last raya, it worked perfectly fine. Their premium Ron95 is our everyday use. If im not mistaken, the price is ridiculously expensive, 29 baht for ron 95. 😂😂😂😂

Yeah our petrol prices are top 10-20 cheapest in the world but people still complaint.

On a side note:

There is no advantage in using higher RON than what your engine can accept. The higher RON is for engines which need the higher octane rating to avoid knocking (premature detonation). It will not result in better power or FC so it is money down the drain.

The new Mazda HCCI engine is definitely an exciting development. We can have the power of turbo without lag or high FC. The FC can be as good as 30km/L.

guys, i heard mazda requires different battery called istop.

1) will the warranty void if we use battery outside mazda workshop? what is the recommended istop battery for mazda 3? i heard getting it frm certified workshop cost around rm400-600?

As long as Q85 EFB (Enhanced Flooded Battery) is dedicated for iStop. In the market you can find these battery from Amaron/Varta/Bosch/Maxlite/Yuasa/Delkor and so on. Price range from RM 400+ to RM 600+ aftermarket price.

If your stock battery is still under warranty, get it replaced free of charge and Mazda will do the resets for iStop, power windows s well as power steering angle position for you. If out of warranty, you cn buy outside SC and get the resets done by your own.

Our Skyactiv engine over here is tuned to 14:1 compression so the ultimate choice will be RON 95 with Spec 121 kW (165 PS). In US, Mazda have to detuned the Skyactiv engine to 13:1 compression so to accommodate RON 91 with 114 kW (155 PS).

PE-VPS (2nd generation Axela )
Name: SKYACTIV-G 2.0
Type: Water-cooled in-line 4-cylinder DOHC 16 valve
Displacement capacity: 1,997 cc
Inner diameter x stroke: 83.5 mm x 91.2 mm
Compression ratio: 12.0, 13.0, 14.0
Fuel supply system type: direct in-cylinder injection (DI)
Output torque
121 kW (165 PS) / 6,000 rpm · 210 Nm (21.4 kgf · m) / 4,000 rpm (CX - 5 · RON 95 specifications)
114 kW (155 PS) / 6,000 rpm · 196 Nm (20.0 kgf · m) / 4,000 rpm (CX-5 · RON 91 specification)
113 kW (154 PS) / 6,000 rpm · 194 Nm (19.8 kgf · m) / 4, 100 rpm (accelerator)
111 kW (151 PS) / 6,000 rpm · 190 Nm (19.4 kgf · m) / 4, 100 rpm (Premacy, Lafesta Highway Star, Biante)

Will higher RON improve performance? YES
Will you feel it while driving? Not exactly.

If you have fat wallet, why not?

I believe the new GVC is possible to have SCBS of up to 80km/h, someone will need to confirm because I've personally driven the GVC and seen the collision warning while driving at around 75km/h, a huge "BRAKE" sign in red will pop up in the HUD. The sensors were set for "early" so there was enough time to brake.

I know that there is definitely no lane assist, just warning only.

just to update.
my car stonky brake pedal solved.
they change the servo. now it is resolved.

and just realised the car paint is full of orange peel here and there DANG.
cant do much about this but sent for paint correction. as i dont think its under warranty
guys before pick up car bring high power torch light and really check the Paint.

next thinking how to resolve the highwindnoise issue.
thinking adding rubber to door and spray wheel arch with dampening material.

thanks for comment. can i have some commonly used istop battery if mazda warranty is over? also would like to ask if outside warranty, can other workshop able to service mazda 3 easily without EVER going to back authorized workshop?

About the ron95 vs 97 debate, apparently there are torque benefits to using higher ron as shown by mazda's latest presentation on their future engines which also shows the current skyactiv engine.

The battery size standard is Q85, just go any battery shop/workshop, they will get the exact one for you and confirm will work. If you're adventurous enough, you can get larger batteries that are listed for stop/start engine use. Even better that you get a lead acid battery charger to prolong the life of the battery.

Normal servicing like oil change/air conditioning service, no need to say mazda, even mercedes car also can be done by outside workshop for these type of periodic maintenance.

Using higher RON only has benefit only if the engine is tuned to use the higher RON. If it is tuned to use RON 95 using RON 97 has no effect.

Your experience shows that the GVC model does have SBS. How it works is that it will give you warning to brake if the rate of approach to the car in front is too fast. If you still don't brake it will brake for you to reduce the severity of the collision not to avoid a collision.

SCBS is another system which brakes completely to avoid a collision but it only works up to 30 km/h if I'm not mistaken.

I think Amaron doesn't have battery with EFB feature...I only aware of Bosch and Varta

Hankook 90D23L
Varta 95D23L
Bosch 95D23L
Delkor 115D23L

I called Amaron and the guy there quoted me one model which he claims is EFB but on checking their website nothing is mentioned about EFB so don't take the risk. EFB isn't a battery with higher capacity, it has a different construction.

Locally got sell 115D23L spec Q85? I want that as it has larger capacity.

Wind noise only appear after 120kmh and is not as noticeable compare to road noise, adding rubber might help to improve slightly but the main culprit is the road noise

Amaron Pro come with EFB 90D23L
Century Ultramax also EFB 80D23L

Note that only Amaron Pro series is for iStop.

The highest performance rating is 115D23L currently available by Delkor as I know now sold by Bermaz SC. Bermaz bring in this model as replacement for Yuasa 90D23L due to too many cases of warranty claims last year.

Bermaz is having Delkor 115D23L as the replacement for previously stock Yuasa battery. I'd my warranty claim to this model 2 months ago due to premature dead of stock battery after 6 months.

If you want 115D23L, Bermaz is not the right place due to higher price they are selling. Probably not many vendors carry 115D23L due it is price much higher than 90D23L.

Any one know where can get and how much it is selling will be good information after all.

Do you know any good and affordable workshop for mazda after warranty period over?

Which one is better or you prefer?
