Yes, I just realized that as well. I went to 2 Petronas and they don't have RON97, only RON95. Why are they doing this?

...maybe we can try mix RON95 with RON 97 and see if there is any knock..I'll try on my SVT soon...full RON95 and Mix 95 with 97
i used to read that if we mix RON95 with RON97, the new RON is between 95 to 97;
let say RON96
is it true?
coz today i accidentally pumped in $20 RON95..dono what was i'm thinking that time

UMW Toyota Motor Sdn Bhd, the exclusive distributor of Toyota and Lexus vehicles in Malaysia, would like to announce that RON95 petrol is suitable for use in all petrol engine Toyota and Lexus vehicles sold officially by the company.

it just announce that all toyota and lexus vehicle sold officially by them is compatible with ron95
but i dont think umw sold any car with blacktop engine before
so, their statement doesn't apply to the blacktop engine..
from my testing, ron95 still can be used - just the power produce is less compare if use ron97
mayb there are some long term effect
by using ron 97 already produce dieseling sound
ron 95?..hmm
but ron 95 is sold with the same price with the previous price of ron 97..
whats that..
mayb malaysia strive to be the no 1 country that produce pollutant
doesn't think about environment or what?..

at the moment no problem wth my bt engine when using ron 95. i heard gov upgrade ron 95 without plumbum. maybe will not effect to our engine but only the power a bit less. early stage ron 95 with plumbum (red colour petrol) when i used to my 4k engine carb its clogged. the car cannot run smooth always mati mati.

Just tested RON95... got knocking a bit especially during stop-go situation in 1st or 2nd gear gear. Also knocking more noticeable when VVT kicks in. Power wise cant feel any difference yet, perhaps someone should dyno compare between 97 vs 95. FC don't know yet but more or less should be the same. Will update on this as well.

However, its recommended to have higher fuel press when running RON95 on 20V engine or octane booster.

Enlighten us on this.

The price of fuel is killing me, are there any ill effects of mixing our petrol? (i.e. using 95&97 at the same time, mixing basically.)

Octane booster are those fuel additives that you add into the fuel tank to improve RON rating and reduce knocking. I've seen them being sold at Jusco and other stores including Ace Hardware. Famous brands are Stp, Nitrous Express and others. Costs about RM20-30 per bottle.
I think if mix ron95 with ron97 shouldn't be an issue, but you will create something new called ron96. :burnout:

Fancy DIY octane booster? Read here: http://www.elektro.com/~audi/audi/toluene.html

anyone tried adding crushed mothballs into the tank? (must be pure naphthalene, not other ingredients) everywhere in the net said it'll increase ron/hp to the engine

I wonder if the maths is that exact:hmmmm:. I'm terrible at math. If mixing them would eliminate or reduce the pinging, that would be great.
If you talk about math, then u need to bring it to the science lab and do proper testing. But logically, I dont think there will be any issue mixing both RONs. The first moment you pour RON95 into your tank, you are already mixing it with RON97 (assuming you were using RON97 previously), unless you drain out your fuel tank and fill it up with RON95 only, which is very unlikely.

Bro cybtech, As for adding crushed mothballs into the tank, I think better not to do this as it might clog the fuel system including the injectors as well. IIRC, mothballs was tested by Mythbusters and they did claim that the engine responded better. I think Toluene should be a better choice to bump up the RON rating. Pls read the earlier link where I posted about the DIY octane booster.

I didn't mean mixing would cause issues, rather mixing the two grades to reduce the knocking in our 20valves, (assuming there is knocking, since now I read that some owners didn't encounter that problem).

Also i'm wondering, will running lower grade octane fuel(like 95) endanger our engines if we're gonna rev all the way till 7000+RPM?

Ya bro pcmoddingmy the mythbuster does indeed said the "engine sounds better" and it's possible but still they haven't really tested the hp or it's mileage. They also tested Actone mixed to fuel the results were worse mpg gone down by 1~2miles. Toluene is new to me, i'll do my home work :biggrin:

RON95 - 95% Octane 5% Pentana
RON97 - 97% Octane 3% Pentana

mix it ? will it get average 4% pentana and 96% Octane...means RON96 ...walauwehhh...

dun worry.. got a solution for the clogged injector and the fuel system, u can crush the mothball and melt it in a storage bottle before pour it into the tank mah.. something like custom fuel octane booster.. muahahaha......

last monday put Shell rm20 ron95 + rm15 v-power. city driving with happy revs, to day almost empty (near 'low' tank mark) total mileage = 240km... previously tried only ron95 less vibration but rev feels quite sluggish. to date only experienced with caltex, esso and shell ron 95; and it does make a diff feels to rev dial.


standrd bt...

I don't know about you guys...but I will not use RON95 on my 20V ...
high compression engine like 4AGE 20V! 10.5:1 for silvertop and 11:1 for blacktop, are prone to detonation...lowering the RON will increase it !!!

using lower RON is one of the causes for engine detonation...

excessive heat, multiple flame in combustion chamber...this will causes head gasket,piston rings, piston and rod bearings to overload...then engine failure... :banghead:

it will put more damage on the engine rather then good...due to engine failure

azuaneman - make the A/F richer won't eliminate engine knocking...it's the fuel RON it's self...
