Quick Petrol Question...

[RTHRTY3]

As we all know petrol prices are phuckin ridiculous at the moment, especially if ur driving imports cars and the like. My question is which premium unleaded petrol is best to use here in PERTH, Caltex Vortex or Shell Premium Unleaded?

And don't say use BP Ultimate...!

I wouln't use anything else other than ultimate on my car, but if you have to use something cheaper then make sure your running low boost and wind back some timing, else you'll be doing as rebuild on the engine.

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

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.

[PHATR32]

i use only 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 makes my car ping like an epileptic at the rise....had to use it when at drift day in collie

Gav, No worries, I'll get fresh BP Ultimate for you, Should have the pics of your bits to you soon:D

Out of interest - what is the current price for Ultimate in Perth? I'm paying 81 - 85 pence per litre for crappy diesel over here in England at the moment.

[dan_the_man]

107 cents a litre

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

[tigeryas]

Caltex = 95 RON, then 97 RON, Gull's supposedly 98 RON, Shell's 96 RON, who's right!?!?!? I have no idea who to follow (I'm using BP Ultimate as well by the way)

My car's been smooth since i switched to Ultimate 98 several months back...

[skyzerr33]

my data is 2 years old when i last checked it all out.

so its quite possible it could of changed.

[GWP021]

well everytime ive been forced to use any other premiun than BP the skys run like crap so ill stick to BP an octane boost evey coupla tanks

[33Spec2]

i can confirm that shell premium is 96octane

(i know this coz i work there )

dunno bout the rest

i only fill mine with shell wen im desperate or the price is really low, plus i get my 4c a litre (which works out 2 about $1.50 off ) otherwise i use ultimate

[Gav]

98 octane is close to $2 ozzie in Bulgaria.

92 octane for my Trabi only $1 - even less when diluted with sump oil, reject vodka (insert random liquid hydrocarbon here)

[ix9]

I only use ultimate 98...

Vortex is SHITE and I can see the knock sensor sitting on 10-20 while highway cruising at 100km/h.

[memphis]

I ran vortex for 20 months with no problems at all, this was at 12psi

i guess its all about seeing what works the best, i used caltex because i had a fuelcard there, and got it free from work, then i just stuck with it as theres no BP's on the way to work.

[RTHRTY3]

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?

[GTS-t VSPEC]

For an NA I'd guess either of the premiums would be fine:D

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:
