hi octane unleaded

**dawnrazor** · 3rd October 2005, 14:03

pulled into a BP station the other day, I was running on fumes so really had no choice. Went to grab the 96 oct unleaded only to be greeted by something called BP ultimate 98 octane, and a miserable 91 octane option. Now I've been advised to run the higher octane stuff so the 91 was out but the 98 was nearly 8cents more a litre. As I said I was on fumes, so filled up with the 98, and can't particularly complain (I mean its not rocket fuel is it), but was a bit pissed that it cost so much more then the caltex 96, which was doing me okay up to that point.

Was wondering what people thought about all that, does it matter, why can't you get 95/6 at BP anymore and isn't it great that now it costs over $20 to fill my tank I can get flybys, bonus - i'm saving up for a toaster!

Doesn't matter mate. BP Ultimate as its called has been out for a while now. Does the same job.

I think it's only 97.5 or something. You could always do Gull - 96 thats actually 97. but still 96 price. I used to always detoured in my car to go to Gull. i think their 91 is 92 as well. w00t

You can still get 96 at BP. "Selected" servos have the 98, the rest have the other crap.

BTW - all the Big4OilRobberBarons are to phase out 96 in favour of "New! Improved!!" 95, to "keep NZ in step with the rest of the world".
More like: "We're lowering the octane rating by one point because the rampant profits we've been making are getting boring so we need a new way to do so."

Yeah,it's only a few that do 98 - if you have a vehicle that only runs on 98 you keep getting pissed off only finding stations that have 96.

Another fuel thread! Yay! From the many other fuel threads I now know that 96 is just 91 with some additives. I know from talking to mechanics that 96 is a dirty fuel- ie, doesn't burn clean and leaves crud (highly scientific word that us laymen can not possibly understand) behind. 98 on the other hand is a higher grade fuel- not just in terms of octane rating, but additives etc too.

Yesterday I thought I'd be a sucker and try some 98 in the FZR. I normally run 91. It has an idle to 3k miss that I STILL haven't bothered to sort out

and dyno runs show it's a tad lean there, so I thought the extra octane might help. It did. The thing actually idled smoothly, instead stuttering away like it normally does. It still stuttered a bit under load, but not as badly as it had been before the good stuff went in. The next step will be to throw some race fuel in when the tanks empty and see if it's better again. Ahhhhh, I lurve the smell of race gas!

What wonderful, wonderful people the Big4OilRobberBarons are!
I remember back in 1996 or whenever leaded petrol was done away with in favour of the more polluting, highly carcinogenic, rubber-eating shit we now enjoy, the Big4OilRobberBarons wailed, gnashed their collective teeth and bitched about how upgrading the oil 'refine'ry to produce fuel of a quality enjoyed in Urp was "way too expensive" and would cost "at least 100 million dollars" and "could we please just use some of the crap that's part of the refining process to artificially boost the octane, instead?" and the Gummint said, "yeah, orright."
So after what - 9 years of enjoying the profits of their $100millllions sitting in the bank, and our crapulent fleet of used Jap imports spewing out sulphur-rich fumes and carcinogenic petroleum distillates, they'
re now patting themselves on the bac and sayin how wonderful theay are, and how they're not going to pass the costs on to the consumers? Yeah, right.

The Blackbird is definately cheaper to run on 98 as it gets better MPG (yes I am old) than it gets on 91.
It runs sweeter and is more powerful too.

I haven't conducted a test on the Yamaha specifically but it also would appear to get better milage on 98 by a reasonable margin.

Initial results on the SS would indicate that it is getting better milage on the higher octain fuel also, though on the early results it may not be enough to compensate for the extra cost.

Frankly I wouldn't use the expensive power-sapping 91 stuff.

You have too many bikes. Good on ya!

Ooops.... sorry.
I keep forgetting to not be a whingey old bastid...
BTW - that balck VFR you scraped off the floor at the auction wouldn't run on 95/96 at all, at all. Probably the teeny-tiny spokploogs it used.

i just had a litre of 98 ultimate fuel tested at IPL in Marsden Point, it came back rated as 98.7 octane. I dunno if it will always be that highly rated but it won't fluctuate to much
