if ur running the stock ecu shell premium will do u fine, its 96 RON. its even better if u shop at coles as u get 4c off per litre :D

caltex vortex is 95 RON and has an injector cleaner in it. it make my car ping with stock ecu stay away from it.

Gull's premium unleaded is suppose to be 98 RON, but i haven't used it yet.

that said if you have an afterward ecu or major mods i would only use bp ultimate 98.

As you prolly know - BP Ultimate is only made in Kwinnana and distributed Australia wide (kinda sh1tza when it's cheaper in Sydney than Perth doesn't it). I suspect that it is also sold under another brand, but have never had this confirmed.

For this reason alone, it should be the freshest fuel providing you buy from a popular station.

Paul, that reminds me - make sure they drain my fuel and change the fuel filter before firing up the new donk- that crap's been sitting in my tank for 8 months now!

Gull gets the dregs of the other fuel companies, kind of the crud that's left over from all of the crude oils

Caltex Vortex is 97RON though, but yeah has cleaner in it

thanx for the replies guys, apparently and sadly my line is a *cough* n/a *cough* :Oops: but yea never use normal unleaded but, always use premiums at least, ok just checked their websites and shell is 96RON and vortex is 95. But the thing is i think i always gets more kms from using vortex, no noticable difference in terms of performance though. and yea i kinda mix the 2 together sometimes, i hope thats ok?

Hi Guys. There is another thread going in the General Automotive about different fuels at the moment. I just left a message on that to direct people to the thread below from back in May. There is a fair amount of discussion in it, but some quite informed views. The main thing to note for us in Perth is that every last drop of fuel that you buy in Perth originates in BP Kwinana. Shell, Caltex and everyone else buy the raw 95 ron Premium off BP and add their own soup to it to make it theirs. Shell claim their standard premium is 96 ron, but they are starting from a 95 ron basic fuel, bought from BP. So anything else that they gain in octane rating is achieved through additives.

BP Ultimate is the only thing to use!

Here's that thread:

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
