Yes. Ron 95 causes underpowered and sound rough. Unless you use a piggyback and tune for Ron 95, then you will feel different. For stock ecu, it cannot fully burn the Ron 95 due to the fuel characteristic not like Ron 97 which easily combust in the combustion chamber. That why I never use Ron 95 on all my car before. I still using Ron 97 although it expensive but at least will cause my engine last longer as the carbon inside is lesser. Carbon is causes be cause of un burn fuel. So Ron 95 is not 100% combust during combustion, imagine how much carbon will cause in the engine? Not said that using Ron 97 will not cause carbon but at least it lesser be cause it easily to combust. That why using Ron 95 on older 4g13/15, it slightly cause pinging.

the car will be jumping with joy when you feed it RON97... trust me... even better with vPower97... I use that occasionally...

Before this, my old car mixed with 97 and 95..but, when used 97, the car more felt underpower. so when i bought waja cps, i thought it cannot mix 95 and 97. It is ok to mix with RON97 if i usually use RON95?
however, i will try to pump RON97 to feel it performance. futhermore, i dont want to tweak my car. Last time, i tried X1R after PE service recommended to me. But there is no different.Rugii...

thanks for your advice guys.

sports tt ....just comeback to kl last night from Miri..trip to Brunei is ok, the route is fine...consider oklah..but fuel is B$ 0.53cent per Liter dammn cheap...outsider cannot buy fuel......others thn tht..nothing much to talk..Malaysia 300 times better

Guys do you know how blue haze waja cps looks like?

Is it the same with Persona SE one?

I 100% use ron 97, unless if its not available, since my car has been tune for ron 97.

after u tuned ur SAFC to ron97, did u see any improvement interms of power and FC?

I haven't tried mixing RON95 with RON97 with any other brands... but I've tried ~50% of Primax95 and ~50% vPower97...

the results??? 100% Primax95 still win hands down... I bet you, even 100% Shell FuelSave RON95 still win hands down in terms of performance... I have never felt my car that lazy and draggy... the difference is even worse compare to changing from 15" to 16" wheels...

Power, yes. But bear in mind I tune it after fixing adjustable cam gear.
Fc, no difference at all.

Don't ever try to mix ron 95 and ron 97. If the tank fill with ron 95, let it left 1 bar only pump ron 97 fuel. Mix ron 95 and ron 97 will cause more worst result.

orait.need to wait my tank almost empty. today, my car feel lazy even i try to push. what make a worst, when my engine rough, my dashboard make noisy too..look like engine has small vibration when i tried accelerate hard. hope can feel better if use RON97.

last service 3 week ago, i told SC about this. they said it just need to re-tune and try 'oil vitamin'.

like

Try Ron 97 for second pump.as first pump still contain Ron 95. Retune? As I know, waja CPs nothing can be tuned except the idle speed only. Other then that, all locked by password.
Oil vitamin? Fuel treatment or engine oil treatment? For fuel treatment, try Honda fuel treatment. Can feel the different. For engine oil treatment, try bardahl 1.

The SC gave X1R for both treatment.that is the 1st time i tried oil treatment. actually it is my 3rd service. my mileage still below 7k.

Many people don't know what the oil additives for. Since we using new engine oil, what for we still need add in a oil additives? Oil additives only add during half of the service millage. After we used the new engine oil for 3k, the engine oil additives getting lesser. Mean the engine oil only contain base oil. So only that time, only we add in the oil additive.

If you guy interest, i will teach you guy how to see a good engine oil additives.

Bro im interested.. pls share..

This i need record for video. pls have patient. Need to finger the oil additive.

yeay teacher is finding good source info

I see..hope it dont burden u so much.

Yup, same color...
