RON95 & RON97 Myths and Facts

[RENESIS VIII]

Well as I mentioned above, I'm now running the ZC31S just using 95, no issues or knocking and power also still fine, maybe just a tad less aggressive if I'm being very picky but no big deal. So, it's not really a high performance engine and it can still drink 95. :lol: Even high performance engines like some Ferraris & Lambos do not require 97. Many high performance turbo engines also can still drink 95 if tuned for that.

So, by tweaking the ECU, ZC31S can actually run on 95 or it can do so on pure stock form? By the way, congratulations on your new car.

What car you driving boss?

E60 530i LCI

Dude... you seriously have problems if that is the case.

I would like to know why... It's seriously funny when everyone else hates it.

Didn't get to try much on the stock map but I think also should be fine.
Thx, it's for my son actually but in the mean time I'm using it first. My wife said I have a new toy to play with now.

but my car have been on petron since esso back then... lol...

shelll the fuel finished fast...
petronas low on power but mileage ok2...
petron gave me good mileage and good power...
bhp more or less similar to petron...(but petron station plenty more than bhp)
caltex..the active cleaning does work!.... tested on my bike that have too many carbon deposits...it actually makes the carbon fragment to flake off upon inspection of the spark plug...

My current experience with RON95 after switching from RON97 is some smoke smell when accelerate very hard. My mech said its normal ?

Car is Lancer with 4B11 N/A, anyone can clarify on this ?

Hi all,

Think my question was overran by other comments, above has been bugging me quite awhile, oh yeah, am using Shell RON95, no knocking or pinging detected but can detect some smoke smells when i rev over 5k. Engine idle and rev as usual.

Thanks,
Ken

I never noticed smell. But pinging was apparent in my old Wira which had a lot of stuff done to it.

After years of not driving manual since your Mitsubishi days in Jakarta, it probably feels great again for you to drive a manual again. How is the power of this ZC31S? Weaker than the 4G93 Lancer that you had before?

sometimes when i pump in ron97 into my waja, i do notice different smell after startup.switch back to ron95 then the smell is gone. could be my nose already immune to ron95 exhaust scent.

If not mistaken,modern with ecu can detect pinging and adjust the timing accordingly but only up to certain extend.could be the engine is adapting until it caused unburnt fuel?
just my 2 cent....

I tried V power racing in VR and yes, the fuel seems to finish faster.
Tried Fuel save 97 VR no power
On Petron most of the time and whether 97 or 95 got power
Yup, for me BHP same as Petron
Caltex and Petronas did not try.....lol

Yeah, it's good to drive manual again. The car is a bundle of fun! It's pretty fast, at least as quick as my CB5 for acceleration if not quicker, maybe just loosing out on top speeds above 160kph due to the shorter gearing (110kph @4000 rpm already). What's even more fun is the handling! The steering is nicely weighted with good feel, the handling is sharp and surprisingly very neutral for a FWD car with excellent grip! However I feel it's also a bit more nervous under braking, especially when braking in a corner/bend as you'd feel the tail gets too uneasy than usual/other cars I've driven. Not sure if this is normal for all SSS or is it just my car. The brake pedal is also a bit too soft even though the braking is good. Other than that, the car is great and surprisingly also very fuel efficient. I've been driving pretty aggressively very often and yet it can still get me about 11km/ltr. So I'm very happy with my purchase.

Wow, gear ratio so short, 110kph at 4k rpm, so high speed engine is roaring......

You should start a thread to talk about the pros and cons of the SSS, and it’s quirks.

Would be an interesting topic. 110km@4000rpm is crazy high. Myvi is about 3000rpm only.

Mine has no pinging or knocking at all, been using it for almost half a year and the smell is still there during hard acceleration. I have yet to switch back to RON97 once in a while. Now my petrol is almost free after recent promotion :)

Thanks,

Engine has long adapted to it, my idle is very stable. It only happens during hard acceleration.

Yeah, very short gear ratio, so it's thundering on highway speeds! Haven't checked with the club if they also have the same or my final gear has actually been changed to shorter. But anyway I'm fine with it since the acceleration is very responsive and since this is actually for my boy, then it should deter him from speeding too high. Also fuel consumption still very good despite that.

Yeah maybe later I start another thread once I got to learn more about the car. :)
