We have Premimax or Premiumax or whatever it's called at the Libertys in Adelaide... I tried it and from memory wasn't much different, slightly worse economy (gotta expect that it has a higher ethanol content). Although my ECU was tuned for BP Ultimate (98).

what state are you in? i dont know of any liberty stations near me

Yeah in Adelaide. Funny thing is, I rang up a Liberty station closer by and the guy insisted there was no such thing as E10 100 octane fuel in Liberty stations :D

I have been using Gull E10 for a couple of years. It is a 10% ethanol mix. You won't get better economy but it will clean out your fuel system so get a new fuel filter soon. Main advantage is you can run a bit more timing (go faster) but of course you need some means of tuning it (Nistune, E-Manage, Link etc).

yes, apparently ethanol has no "knocking" not like regular petrol, so alot of people use it in racing cars etc. but its not a self coolant like petrol, so running anything more than about 20-30% you need a cooled head.

Cooled head? Not sure where you are going there...

I tried the United e10 100 octane and wasn't impressed. It didn't seem any better at knock protection than the BP98 I was using.

I have since tuned for Caltex e85 eflex, a much better fuel. Power is up 50kw, 20% more torque, lower egt's and no more pinking/knock. If anyone gets the chance to tune for ethanol, do it, you wont regret it.

2 points of difference in octane isnt much, youd probably expect slight variation anyways from batch to batch of fuel. E85 is like the equivalent of what, 106 octane?

I am interested, but what about for a purely economical replacement for premium grade fuel?

At minimum you need aftermarket fuel management, maybe larger injectors, dyno time for tuning, and a fuel system clean?

Then did you find a 30% increase in fuel usage, and how much do you pay for E85?

I have found it to cost about the same as 98 once the lower price is taken into account. Caltex sell their E-Flex for 20c less than unleaded. Cheapest power upgrade I have done as I already had the supporting mods.

A Walbro pump and seimens deka injectors (for the neo motors) wont set you back more than $600 but you will need some way tuning it.

The ethanol will strip clean the fuel system so you would need to change the filter after the first few tanks. Ive been running it for 8 months now with no issues with the stock fuel system.

Goddamn Scotty you are sooo tempting me. $600 + tuning = 50kw gain!!?

Then again I gotta get my zorst done 1st. Is there any point doing this on a Stag without a hi flowed turbo and emanage?

the last time I used liberty ethanol premium (on way to p/up momo wheel from mike) I put in half a tank, ran it dry and didnt boost it much.

seemed down slightly on punch/power and a little iffy, wasnt comfortable with it seeing my Fic-8 piggyback & remap is tuned for premium 98 (I use mobil, bp or shell)

after the half tank was used up, next tank of premium went in under 200kms, same with tank after that.

fuel economy went shithouse.

ripped out the fuel filter and replaced, fresh tank of 98, and got 420kms before the low fuel warning light came up

considering she used to get 420kms per tank with 120awkw, happy that its around 400kms with 240awkw

will try the liberty ethanol blend again soon, to clean out the carbon deposits, soot, etc, and replace fuel filter again afterwards. definately clogs up the filter!

Yes!!

It works better with more boost, 20+psi, our engine compression is too low to run ethanol well, without pumping the boost (which I wouldn't like to do with the ceramic exhaust wheel.) but yes you will still see a gain.

Some people say 5 degrees across the board but I prefer to let the engine do the talking. There is no set figure, every engine reacts differently.

WOT dyno tuning for maximum torque at the least timing advance is the safest way, much better to bump the boost up imo, mine feels good at 22psi. :(

  • 6 months later...

Yeah, I went to Liberty a couple of weeks ago, went to fill up with the 100 that I had been using. . . The Pump said 98 and the bowser said 100???

I went in and spoke to the manager and he said they were in the process of changing all the signage over to 98 as the fuel was not actually 100. Not sure if it never was or if it was then changed back?

I was running the United 100 octane E10 and found a substantial difference in my car, car seemed all round happier and fuel economy was consistent (no idea why, figured it'd be down).

When it got removed from sale I contacted United, and to their credit they got back to me very quickly. Contrary to what the bloke at the servo told me, their 98 has no ethanol (it used to before the 100 came out). They've run out of ethanol because of the Queensland floods apparently and expect to get it back later this month. Then it should be available at all the servos.

Scotty, good suggestion but I'm yet to find a Caltex in Adelaide that stocks Eflex DAMMIT! You can still only get E85 from specailised race fuel suppliers, although there may be a couple of other servos that stock it now.

I have no idea why you Mexicans get it and we don't... >_<

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
