It's been like 2 - 3 weeks now with no Ultimate. I've had to use some Synergy 98 & Optimax.

I want Ultimate again! Anybody who always uses ultimate but is having to use another fuel feeling the difference? speak up.

I think Optimax has been slower, 3rd gear 12psi just isn't pulling as quick I think.

I have been using vortex98 for the last few tanks and fuel economy is exactly the same.

The car does pull harder in 2nd and 3rd!!

I was suprised but my car runs better on vortex98 than ultimate or optimax.

I'm of the understanding that most of the east coast has got an Ultimate shortage, with stocks to be restored at the end of December or early January.

I've been giving Synergy 8000 a go, I'm on my 3rd or 4th tank, I've noticed that power seems to be ever so slightly up, though my fuel economy has dropped slightly.

yep, there's been none in my town for at least 3 weeks (2 BP's, both out).

is really beggining to sh*t me cos i gotta drive 15 mins down the road to get optimax, or remember to fill up when im passing a shell/mobil out of town.

tried vortex and wasn't real keen, my knock levels went higher than i've ever seen them (although was a warmish day and car is tuned for ultimate).

Well ive been running on synergy 8000 and recently swapped to optimax extreme.. and as far as im concerned it kills bp ultimate. I've got noticable power differences, specially after re-setting the ecu.

Though will good to be back to ultimate again, no ethanol or anything to worry about:)

i think the "Ultimate" part in BP ultimate's name has a lot of people fooled lol

I think you'll find most workshops agree you can tune the hardest on Ultimate for any pump 98 fuel in Aust.

#1 Ultimate

#2 Synergy 8000

#3 Optimax

Some people say Synergy is a tad better than Ultimate but usually Ultimate is the prefered fuel for tuners trying to get the most outa it. I got the most power & lowest knock out of my car tuned on Ultimate.

how do you go about resetting the ECU?

Disconnect the battery, press the brake pedal to drain all the remaining power. Maybe leave it for a while then just hook the battery back up.

And I've been using Optimax since they went out of Ultimate and to be honest there is no difference at all imo. :(

i ran my car on ultimate all the time and i found it pulled harder, had better economy and ran better, less lumpy in the idle. Using vortex and sh*t like that made my car crap, noticed it clutch kicking at pt.g last week.

GO BP ULTIMATE!!!!!!!! please come back to me

Sounds like you guys over east are just getting what we went through over here about a month ago. The refinery had a problem so they couldn't produce anything but normal unleaded, so most stations were without 98 for a few weeks. Over east was still ok because they stockpile it I guess. Now that it's normal over here, that was probably the priority so all the fuel has probably came to us. :)

It won't be too long I imagine. Unless there are BP refinery's over east, I would think there would be which would mean I'm babbling shit.

You lot are complaining but over here Ultimate is the only 98 fuel we can get so it hurt us a LOT more!!!

Ultimate is more expensive than extreme 100 here in QLD... On any given day BP is at least 2 cents dearer than shell at aspley and virgina....

So i stopped going to get fuel from BP along time ago...

I had the fc tuned on optimax and found extreme to knock a bit more but the extra 50km;s per tank has not rally made me a fan... ill stick to 98 plus i get 4c off a litre at shell also...

So thats a saving of about 3 bucks a tank... I also get a 600ml coke when i fill so thats a free coke in my books....

50-60 litres of fuel for the car and 600ml of coke for me....

    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
    • LOL, all of the CAI like Craig I just need to put a hole saw through my bumper Done and dusted, the car runs, which is nice, I'll take it for a spin when the weather clears up Just need to put the bumper back on for good

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
