so yeah, who's on the juice of the 100 RON variety?

Can't say i even know where my closest Optimax Extreme servo is... but was wondering if there are any/many people using Optimax Extreme?

Heard some really good reports from SK, he's had it running in a 33 GTST for 8 months, seems to be good stuff...

anyone which servo's have it on the s.e. side? bayside way? Telstra has "shaped" my cable, so it's painful to search for stuff....

If u go to the Shell Website, it will has a current list where to go Extreme.

There is also a list which cars can / cannot use it.

Not sure for u guys, but some subies cannot use this fuel.

Cheers

Appears as though it's just Optimax with 5% ethanol....so WTF is it 6c/L more??? Ethanol is cheaper than fuel.

GTR already has 260rwkw on the stock computer with Optimax so no point changing.

whilst it will help take out some detonation if you have any its pretty much pointless on a stock ecu. aftermarket ecu owners can tune with it and get some more zest but the stock ecu will achieve zero. even doing the infamous ecu reset will probably yield jack all.

been told by a reputable mechanic it is v-good. my car is tuned o 98ron and i use optimax100 . a big horsepower car could get a possible 10-15kw more if tuned on this fule so i bee told. i find it more responsive on the pedal + i get an extra 60km's out of a tank. almost 500k's for a daily driver is not bad :laugh:

extra fuel consumption from using higher octane fuel is not possible.

i see no reason you would gain an extra 60kms from a tank of higher rated fuel. if anything it would be slightly less. i dont believe it for a second im sorry.

I did some tests in both my cars on the extreeme and ultimate. Correct me if I'm wrong by most jap imports ecus are designed for 100RON but can adjust enough for comprensate as required.

anyway regardless of if thats true or not, I ran 5 tanks on the xtreeme and 5 on the ultimate, ultimate ran better and I got the same kms, if not slightly more but hard to really tell. So I decided just to buy ultimate cos its just downt he road.

Saying you get over 500kms its not really relevant unless u stipulate what type of driving your doing. I drive to my holiday houe and get over 600km and in CBD driving and peak hour I might get only 420...

the stock ecu has code to back off timing when it picks up detonation. it wont just magically advance the timing and make more power. an ecu reset clears the map and tries 2deg advanced and watches for detonation. thats about all the "compensation" it does.

it has no idea what fuel you are using. it only knows when you have shit fuel in it, that detonates and is seen via the knock sensors, only then does it act, and thats back off timing to protect itself

Agreed the Gov gave the ok to use Ethanol, to help reduce the price of fuel and yet this is more expensive. What Crap!

As most of you guys, if ur running stock ECU u will not notice much of a difference. If you just buy an aftermarket ECU and tune to this fuel, ur not acheiving much. Unless ur going to be doing some other big mods.

Personally l have turned off the shell optimax, l have found most of the time the alternatives from Caltex and BP have been cheaper.

      Blue slip

      By GTSBoy · Posted

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?

      You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height

      Ethanol Content Sensor - Always at 11%?

      By Duncan · Posted

      yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia
