that's not true, using 100RON is a great insurance policy on track days etc where you are worried about detonation without the skill (or ability) to back out timing from your tune or run less boost

but you can't buy 100RON so it doesn't matter. 98ron is all good

Like most I use bp 98 exclusively but had to change to the shell 98 when i went to wakie for 3 days of track madness recently.

the shell product never gave a hint of trouble and the plug colour was as good as ever it was with the bp.

Will continue to use the bp as it is only a kay from where i live but would have no probs using the shell product when the need arises.

A couple of years back when I was runing a pfc I did a holiday on the norhtern nsw coast. There waer 3 servos almost next door to each other so I filled up with 98 from bp, shell, and caltex on 3 different occasions and went cruising on much the same glorious roads each day.

The caltex was the surprise, It gave lower knock readings and the car ran better on it. draw your own conclusions but if i had the caltex 98 more readily available I would use it more often.

I'm not 100% sure, but I think most of those fuels come from the same refinery. The main difference is likely down to the freshness of the fuel.

IIRC BP, Shell, Mobil and Caltex supply each other fuel in different areas around the country, ie. pretty much all fuel in Melb comes from Mobil and Caltex as they have refineries here. BP and Shell supply Sydney and Northern NSW, and so on.

I'm sure someone here works in the industry and can clarify how it all works.

That sucks v power is 100 Octain in the UK

Even the Supermarkets sell 100 Octain lol

Personally I think its all a con anyway. I ran my car on 95 for over 2 years no problems even run a few 1/4 miles on it no problems managed a 14.27 pass @.5 bar 255bhp pritty much stock

Even managed 299bhp on the rollers on 95. and the a/f was said to be spot on. Although I will admit since the boost was increased and only since then it feels like it runs better on v power or the supermarket stuff.

But when it was stock 100 was not needed plus i can not believe that Nissan would have only mapped these engines to run on 100 or more they exported them all over the world in one form or another.

Just my 10 cents

It may well be fuel freshness, I am no expert on the fuel industry, I can only give the real world experience I had at that paticular time.

yes fuel companies share tanks and fuel as not all companies have refineries in every state so they share

and fuel does loose its octane count over time, so old fuel will certainly affect its level of resistance to knocking etc

this is more than likely to explain the level of resistance to knocking vs a specific brand

ie in some cases shell fuel will actually be mobil, and caltex may be BP

often i see people post up brand XYZ is evil and kills injectors, motors etc blah blah

i believe its more due to the fact of age of fuel at the servo vs a specific brand

Agreed. Used to get V-Power Racing when it was available and knock was eliminated almost completely. Struggled to get readings over 15 with 250rwkw, redlining in the middle of summer. Brilliant stuff.

United still sell 100RON

Shell have their own refinery here in Melbourne. The fuel terminal at Yarraville (under the westgate) is where all teh fuel truck fill up. They each lease the tanks from Shell and Mobil. Here's basically how it breaks down.

Shell have their own fuels

Caltex, Mobil and BP all share the same fuel under 98 Octane and e10 (in other words, they all get pumped out of the same tanks but put into different trucks)

Caltex has their own 98 fuel.

Mobil and BP share the same 98 but BP puts their own extra additives into it, what this means is that you can always turn Synergy 8000 into Ultimate but you can't turn Ultimate into Synergy.

As far as I'm aware they all get their e10 from the same place but get different blends of fuel to go into it hence the different RON they have. BP do have an e10 but it is not at the metro sites yet, only in the regional sites run by Reliance Petroleum.

Only reason I know all this is because I work for Reliance Petroleum who are the largest Australian distributor of BP Products. We are also a national distributor of Castrol.

I don't get a discount for working for them but I still use Ultimate as it has been the best performing in my car. I did also have great results with Caltex 98. I wouldn't use Shell V-Power personally unless there was no other choice, it goes stale quickly and loses it's octane rating faster than all the others, not sure why. I also got 80-90km less per tank out of it.

They say oils aint oils so I guess fuels arent fuels. I want to see the Ultimate 102 fuel that BP rolled out in the UK here but it's not going to happen now since they stopped selling it in March this year. The stuff would have been sweet Clicky!!

yeah and do you no how much they charge

Nearly $5 a lt!!!!!!

and its not on every bp fore court only selected places have it and I only come across ONE place and that was at Silverstone race circuit.

Or though the likes of santa pod drag stip will sell you 20lts of "race fuel" for about $150

Isn't normal juice about $3.00/litre over there anyway?

they couldn't have t at every servo because there was no need too. It was made in small batches of 20,000L and was the same fuel used in F1 for the winter season for $5 per L it's pretty steep but they were selling plenty of it, pitty the refinery closed that was making it :cool:

The only reason v=power racing was 100ron was because they used ethanol to bump it up, what was bullshit about that is the fact that they sold it for 5c a litre more than the normal v=power 98ron. It dosen't make sense when you see e10 unleaded sell cheaper than regular unleaded.

I wish it was still easy to get race fuel for the odd track day but good old emission rules and regulation screwed that.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to it's full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so damn hot in there, that made it all the more easy to remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. I was standing there looking at the car and said 'f**k it'. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
