I've heard someone say that 98 Octane fuels offered by the different petrol station brands are different in their makeup, and apparently BP ultimate is the better one to use. Is this true or a load of waffle? Does it really matter if someone uses V Power or BP Ultimate or Vortex 98?

I think BP Ultimate is the only one to be guaranteed to have a minimum of 98 octane, so its a safe bet for a tuned car.

I personally get good results out of VPower.

Also, Happy Birthday Ruby!

if its a pure petroleum based fuel advertised at 98% octane then by law it has to be 98% with no additives. BP and Mobile and Caltex and Coles all have authentic 98% octane. (I mainly use Mobil myself but the others have been just as good).

Just steer away from the United '100% octane' as it is an ethanol blended fuel and can affect your tune (unless your car has been tuned for that fuel especially)

-D

you know the octane rating isnt a percentage, yeah ben?

i do now

I thought vpower was 98? ohwell if thats the case I wont bother spending my money on it, as its the same price caltex sell their 98 (which is the same as mobils incidentally)

-D

V-Power is definitely 98 Octane:

Their 95 Octane variety is just called Shell Unleaded 95.

LOL, this whole time I thought it was 95, and the 98 was called Shell Optimax... (Not sold here Or did V-Power used to be 95?)

Wait, doesnt look like they sell Optimax anymore..

http://en.wikipedia.org/wiki/Shell_V-Power

There are different grades of V-Power all over the world, including a 95 RON version, so that must be where I got that from..

V-Power sold in Hong Kong reaches RON 107; it is the highest native RON in consumer grade commercial petrol across worldwide.

a few people said 4g put it down its only a dog be farked lol i would spend it all again if i had too

happy bday ruby

Thanks guys ... had a good day with family ... even got an awesome present.

Tickets and accommodation for Sydney for the Top Gear show! Was wondering why Tracy was getting moody that I was planning it for myself :)

Wanted a brake upgrade ... but thats asking too much :mage:

I wrote a little poem...

spare time + beers =

"Twas the night before Christmas, and all was so quiet,

The hills were so silent, not a reindeer in sight,

Till along came a skyline and made shit-loads of noise,

So much so, Santa dropped all his toys.

Children in bed, snuggled, warm and unheard,

Till the skyline popped flames down-shifting to third.

While the fat man struggled to pick up his gifts,

The GTR lost traction changing to 5th!"

hmmmmm i lost like 5 + kw after using the V power and i got the dyno graphs to prove it....even going back straight onto the BP Ultimate after realising the 34 lost power didnt change anything :mage:

im keeping her on the Ultimate forever now lol :)

And i thought boost controllers were for pussies :mage:

they are. :)

unless both dyno runs were done on the same day, that 5kw "difference" isnt worth the paper its printed on.

This happened twice tonight, I'm going 55 in a 60 zone (to conserve fuel) and in both cases, a cop in front of me slows down to around 40, even when he has other cars behind him. Once he realised that my car is completely stock they turn off into some random side street, probably pissed off that he won't meet his quota tonight :)

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
