This may not be to do with "what fuel is the best to use" etc, but it's quite amusing how people complain about the price of petrol, when 1litre of coca-cola is still more expensive than 1litre of fuel!

BP Ultimate 98!

I also filled up with Vortex on a stock r34 - definitely noticable. I would argue that you may not notice it if you drive your car ><30% throttle then yes it might be all the same. But I tell you once boost comes on and you wonder -- hmmmm I remember there being a bit more response & torque..

I once had to fill 95octane, I swear one day in the CBD - approx nov 2010 3 different servos had 98 out of service - I tell you this is the time I started believeing in the dodgy wednesday outof service policies where some servos take 98 out of service. Under no circumstance would I ever use 95 but I was so low I had no choice.

And hence 95 octane made the car feel like a 2ton hiace van.

Fact - The base fuel that the majority of fuel companies in WA use is from the BP refinery. I say most because some cheaper brands like Gull, Peak, United et al, import some of their base from Singapore as they may get it cheaper. Hence, why you never know what type of fuel is in them

Fact - All the majors spend millions of dollars on chemist, physicists to come up with mixtures that give them an edge over their competitors, so even thought the base is the same the end product is totally different.

Fact - BP Ultimate 98 is the only 98 RON fuel that is made as a 98 fuel from the start in WA. Shell do not supply their Optimax anymore anywhere in the world, they supply V-Power over east because they have refineries in Geelong (Vic) and Clyde (NSW) and ship/truck it to QLD, SA. Transport costs prohibit the supply in WA and they do not want to give BP their ingredients for them to make it at Kwinana, competitive forces at work. All the other 98 fuels in WA are made from additives, so to speak.

Fact - Not all fuels are the same, and anyone who thinks so is kidding themselves. A perfect example of this is Ethanol fuel, even with the same Octane rating you get less energy from it then an equivalent RON non ethanol fuel. Sometime you can get more power from 95 RON than 98 RON fuel if the density of the 95 RON is greater, but only if your car doesn't need the heat protection of higher RON, e.g. turbo cars.

Fact - They all have to comply with governemnt regulated maximums in sulphur, benzyne and minimums in RON but there are a lot m ore other factors that are not regulated and the different fuel companies use this for the competitive edge.

How do I know all this, I work for one of our fuel majors and have lived both here and in Vic. I can honestly say that the best fuel in WA is BP Ultimate 98, but overall the best is Shell V-Power, as I used it when I was in Vic.

So, go on and use the cheapest fuel or the most conveniant location on your pride and joy and you certainly will not be getting the most out of it and possibly damaging it.

I don't notice any difference between Caltex 98 or BP 98 on my car.

Currently using BP atm, since I got a $100 BP gift card from my parents but otherwise I mainly use Caltex since its cheaper.

only problem with this is its never regulated after being at the servo and its very hard to tell when they're getting low. i've had bad batches from low servos a few times and there is no way in ther world it was still 98RON.

at the end of the day, its unlikely your gonna notice any difference between different brand of 98 on a stock car. if your cars been tuned, use whatever fuel it was tuned with. if its about to be tuned and you can afford their ridiculous prices, BP ultimate is usually the best.

JonnoHR31, the best regulator is the customer...if you suspect someone was ripping you off you can report it to the Consumer Protection agency. It is their reason for existence to help you out and investigate this. It is often the case that the most powerfull people, the customer, don't do anything 'cause of the attitude of being just one person and that is why some business's et away with ripping people off!

Yeah straight out I've been reading all the posts and to be honest I think sometimes Caltex Vortex 98 could even be better than BP Ultimate - but this could be due to fuel density or some other variable that has nothing to do with octane rating.

Caltex Vortex 98 is always cheaper as well but I am a born and bread BP fan especially after reading the big post a couple up haha :thumbsup:

yer i know but by the time they get around to testing it they would have probably filled up as its usually only the nearly empty servo tanks that give you trouble.

u.k is tiny, they barely travel any distance by car, hence why higher fuel prices arent as bigger deal as here and the US

    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
    • Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.
    • The fact that US/JDM plates actually fit the skyline bumpers properly is a big, big thing for me as they are the correct dimensions. Annoyingly you can't opt for a normal plate (or plate combination) in that size. You have to make up your own one, and at that point you'd still know it wasn't randomly assigned. 
    • Well, really, that's any ECU, because it's not so much the ECU that the tuner connects to, but a laptop that's connected to the ECU. You have to have the tuning software installed locally. The "remote" part is essentially just remote desktop (RDP) or VNC type access. Nevertheless, if you're looking to upgrade, then you're immediately in the Haltech/Link territory, both of which can be done by any number of competent tuners here in Oz. But without a dyno, you'll definitely also need a wideband O2 sensor fitted, and you'll probably be relying on "auto" tuning a bit, where you drive it around under various loads and then apply the corrections that the ECU learns (basically applying the fuel trims that the ECU has to do to correct the mixtures). Tuning the timing is a little harder. It can be difficult to trust the old OEM knock sensors on RBs, so it is definitely best to have someone who knows what they're listening for, with knock ears (a piezo microphone connected to the engine, and and little amp and headphones so the listener can hear the angry men with hammers who live in the engine). That is more difficult to do remotely, and I suspect the only sane way is to be quite conservative on timing. But that's OK. You're probably waaaaay better off with conservative timing where you are. What is the fuel situation? 98RON available? Or low grade jungle juice?
    • I see your point, I didn't think too deep into it, was purely focused on the price. There's no bad blood between myself and GSM, they acknowledged the price was cheaper else where and at the time couldn't match it.
