Shell has released a new fuel Optimax Exteme.

It is at least 100RON blended with 5% ethanol.

The shell near my house stocks this fuel and I filled up a tank thinking it was regular optimax.

Anyhow, my car stalled, and jerked continuously. It would not start at times, and just ran like crap!!!

I highly recomend you do NOT use this fuel in your skyline, or any high performance nissan!

I took this from the subaru website, and I guess this also applies to forced induction Nissans also...

All model year Liberty B4 and Impreza WRX STi MY99-00 models may experience starting and or drivability concerns if ethanol blended fuel of any level is used and therefore we do not recommend its use.

For a list of Shell servo's that stock this fuel, visit the shell australia website, and follow the optimax extreme links....

Ive used 10% Ethanol blended fuel rated at 98ron, and it was SMOOTH-AS (it was say half a tank of E98 and half tank of BP 98) in my RB25det.

But I wouldnt use E-blended fuel all that much, only in half tank lots every now and then.

Apparently if you want top performance on regular pump fuel you'll actually find these ethanol blended fuels provide the best performance as long as you get a TOTAL retune. Else I'd probably steer clear as if you have a highly tuned car it will lean out alot more using an e10 or e5 fuel.

well when i was at 1/4 of a tank, i filled up with regular 98RON optimax, and within 1km of driving, all my problems were solved.

Nissan recomends you dont use it, I have provided my experience with this fuel, Just trying to warn others...

thats the beauty of a remapped ecu just pull battery lead off and leave, come back all is forgoten, i wll only try this with half tanks at first, utilmate 98 plus the 100 stuff.

hu? Its not a remapped ecu then. :)

I used a full tank of E10 fuel(10% ethanol) and the car ran great,but my current tune is a little rich.Can someone PLEASE post up Shell servos that have 100 octane fuel in Melbourne.I'm going to tune both my Nissans for this fuel.

I'll be following this thread to hear about peoples experiences before I fill up with the stuff. I've got a stock ECU with a couple of mods, so it runs rich as anyway....

It states it in there.

Extensive tests were done, some of which were displayed in a recent issue of Zoom of HPI (can't remember which). Basically, it needed some serious retuning; heavy increase in fuel, as it is less dense, and a huge advance of the timing, with a 16 rwkw increase over normal 98 ron fuel.

if you goto fcai.com.au it says there that nissan dont recomend using any ethonol fuel in any car made before 2004.

hence y i wont use it.

Exactly.

And Iexperienced the problems mentioned:

- difficulty starting

- poor drivability

ummm.... 100ron.... aint japanesse fuel an even higher rating... why would our cars have a problem with it........ obviously its just tuning... reset the ecu should be fine... it will return to factory specs... as in japanesse factory specs where the fuel is a higher octane rating...

as for the ethonol... the media gave it the name its got...... id rather see the FACTs on this fuel.. strait from the product producer..... i dont think it would do much damage at all.... and seriously guys.... most of you would rebuild you engine before the effects this fuel supposably has are noticed....

of course with progameable ecus you would retune the car when using a higher octane fuel... especially if you want to take advantage of the higer octane.... your stupid to think a totally differant fuel wouldnt cause problems.

b/c of the ethanol

and seriously guys.... most of you would rebuild you engine before the effects this fuel supposably has are noticed....

Is this comment based on more research, or again is your arse doing all the talking?

How can you determine how often people will re-build their engines?? and secondly, by making that comment you basically admit that you think ethanol WILL cause damage.

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
