Either using RON95 or 97, will not cause check light to blink.I guess i had use ron95 for more than a year, first it is o.k for my car,
but lately ....everytime i fill my car with ron95..my engine lights will blink...and the car loose much of its accelerations power.
when i fill it back with ron97 the engine lights still blink, but after a while it will off.
Due to economic factor i have no choice but to use back ron95, and until today, i drive my car with the engine lights blinking..
AE101 Superchargerfor my case, the knocking sound is more quiet when I use RON 95. When I use RON 97, knocking sound is quite loud. Does it mean if those people use RON 100 in Japan, the knocking sound is totally gone?
At 1st i thought the fuel quality may contribute to the knocking sound.How can we ger rid of this knocking sound (sounded like typewriter, or diesel engine, tak tak tak tak....never ending sound) ??? I find it rather irritating. Anyone has experienced / know how to get rid of that sound?
I'm assuming the diesel sound appears during engine idling too...not during acceleration...for my case, the knocking sound is more quiet when I use RON 95. When I use RON 97, knocking sound is quite loud. Does it mean if those people use RON 100 in Japan, the knocking sound is totally gone?

If do...that particular sound is well known among 20V enthusiast...
It's the sound of VVT pulley...

I've been there.. the check light blinks every now & then.. on my SVT..I guess i had use ron95 for more than a year, first it is o.k for my car,
but lately ....everytime i fill my car with ron95..my engine lights will blink...and the car loose much of its accelerations power.

yup...the sound will get louder when the engine is hotter... it's normal...Yea it happens also during idling. But when you start the car for the first time in the day (perhaps morning), the sound is not there. When it starts to get hotter after 5-10 mins, the diesel sound will come back. Is it from the pulley as what you said?
bro, thanks for sharing. Now, I know why the engine lags from 2K to 3K rpm when I use RON95Previously, I really hated RON95 but thanks to RON95 xtra by petronas, I can feel that 20v is alive! Not really promoting petronas brand by any means, but it definitely improves performance a bit on 20v and reduces knocking/pinging. For those without piggyback, I'd suggest to retard the timing a bit (with a timing gun) and increase the fuel pressure (if you have an adjustable FPR) as it helps with RON95 quite a lot. Also, CAI will lower intake temperature and reduce the change of knocking as well.
With VVT indicator mod, you will notice that knocking will usually occur when VVT kicks in at low rpm (around 2000-3000rpm). So i'd suggest to ease of the throttle a bit when it knocks and floor it once you're up in the higher revs.
Cheers
YES, EXACTLY!!!! But the one in this video is quite serious. Mine is slightly better than this one. Damn, I hate that sound... It's like you lose faith in the engine and never know when it's going to break down on you.yup...the sound will get louder when the engine is hotter... it's normal...
does it sound like this ?

I can vouch for that statement too. Was using Shell 95 all these while & knocking/loss of power is pretty apparent. Better power with Caltex/BHP/Esso but lesser milleage. Went for Petronas 95 Xtra since a month ago and been happy with it ever since. Reduces knocking/pinging & same milleage achieved as per Shell's.Previously, I really hated RON95 but thanks to RON95 xtra by petronas, I can feel that 20v is alive!
