i wouldn't mine giving it a try if it its cheaper than 98ron

Well I have a 4AGE Silvertop. I am told they are tuned for 100RON. But who can definitively tell me about the suitability of my components with 5% Ethanol?

i get way better fuel economy with 98ron... 450km on 91 and 600km+ on 98.
i dont get it

Generally most higher octane fuels will get better economy, performance obviously depends on the cars state of tune. Might get a marginal gain in normal cars.
I'll never run 100ron ethanol blended cos my car isn't able to take ethanol based fuels pure and simple.

I also used to get way better economy on my CB Lancer (carby) with 98 than I did with 91. The car also seemed to run better and didn't ping at low RPM.
I've never put anything but 98 RON in my Integra.

Handy for those folk with jap import motors running standard ecu

BB you might have to be careful, because it's not just the engine and its connected bits but the whole fuel system as well that you have to know is suitable for fuel containing ethanol.
Your injectors and engine might be fine but your lines and pumps may be adversely affected by it. Some more research might be needed before people like you or I with "late" model import motors in old school cars use this stuff .

True True!
Was getting a bit ahead of myself there
Well time to research hey?
But i guess the bottom line is how much better performance and or economy could a 100ron provide over a 98ron?

couldnt you like fill , 30L of 98 and 20L of 100 ?
that'd make a ORSM fuel , it would equal it out to 99 ron !!!!!

what cars are setup to run ethanol?
im thinking of running my jdm 4age on something like that??? but i read someplace that ethanol kills the fuel line and run hotter?

check the government website setup for it, there is a link to it off the shell website for the 100ron extreme fuel.

doesnt it burnout the rings quicker or the motor or somthing on these lines, also would u think its suitabe for a stock smallport sx corolla motor?
may be a stupid question but is higher octane suitable for cars that have higher timing?

Isn't it the higher the octane the hotter it burns/runs?

the higher "octane" number means that it is less likely to pre-ignite or ping.. it is a number that is given based on the testing procedure which you can gogle for
there are a few very good tech articles around the net about octane and what it means..
basically, octane only very loosely describes how the fuel will work in any given engine.
on PF someone mentioned results of a dyno test (a proper test ) where they were given some of the new fuel to see how it performed...
i think the end result was that they had to add uel across the entire map, but that they could also and timing, and this resulted in a net increase in power.. and also means that cars running a stock ECU are likely to run leaner as a result.. good for some engines.. bad for others... but without changes in fuel or spark, there was a loss in power across the whole map.
yes, research is needed BB but you can be our guinea pig

High Performance Imports had a test on an E10 98RON fuel. They had the same results. They tested on an R32 GTR which had like 289rwkw, tuned with APEX'i Power FC.
They found as soon as they switched to the ethanol based fuel the car ran really lean to the point where they couldn't do a dyno pull. They added fuel to it till the mixtures were acceptable again, and then found out they could run more timing. They ended up with like 311rwkw, which is probably a fair indication of what's capable.
It's a good thing...provided the car is tuned for it, or has an ECU which can accomodate the change.

I should refraise, I understand what octane is (to a point), what i was trying to get at is, if you filled up with say 98RON and then added some sort of octane booster, the engine would run hotter wouldnt it? So effectively, if you use this 100RON fuel everytime, would there be a noticible difference in the running temps?
Im asking for all those of us who run teh p00 engine and fear heat! hehe

ummm..... why would it run hotter? higher octane fuels typically have lower energy, so you need to use more to get same amount of heat.
to get same power, you need same heat, so i dunno why they would run at castly different temps.. morelikely temp change would be related to rich/leanm and spark advance perhaps?

Basically "bang" does not equal "heat" when talking about octane ratings.

i was under the impression that the higher the octane the cooler it burns.
(which oldcorolla's probably already pointed out)
i dont read good like.

Obivously I was mis-informed then!

Yeah higher octane runs cooler. Ethanol contains less energy than petrol though. So if it started to lean the engine out a bit, that'd make it a bit hotter. But I think that'd be counteracted by the octane... not sure.

But that page is only about E10. Opti100 is E5. I e-mailed Toyota Australia about it. Any bets on the quality of the reply I'll get?

my mate baught some of this a few days ago.
he always used optimax. and he recons this is just regular optimax with E5 added. but it cost him 10c/ltr more.

E5 or E10 makes no difference. i still wont pay more for something that was not designed to go in my car. if i need more octane, i buy octane booster.

How much octane booster do you neeed to hit 100RON. Most of them shift it a few points (ie 0.1 RON), not big numbers.
