BP Ultimate

[saltydog]

Filled up in Tow-rags this afternoon at BP. Two bucks a litre for the good stuff. Geeze. What next, ban the motorbike?
The sad thing is, I'll just have to keep buying it!

[Boob Johnson]

Tis a sad day alright. We live in changing times with some major changes on the way :blink:

[Animal]

I don't feel so bad now...

Last weekend (ANZAC Day), I paid AU$1.75 a litre for a tankful of Ultimate, which was definitely the most I've paid for petrol over here on the West Island. It was in some obscure little country village, so the bastards ramp the prices right up! Earlier today in suburban Perth, it was AU$1.57 per litre.

I still miss NZ though... fewer Australians.

But WA has the best Australians :lol:

That's your problem - BP.

On anzac weekend, Mobil was 9c cheaper than BP. I got 98 ("Synergy 8000") for $1.909

See this is the problem, you are bragging about paying $1.90 for go go juice :scratch:

Yeah, this is true.
Aside from seeking out and abusing all the twisty roads Southeast of Perth, I'm trying out all different species of local wines at the moment. I haven't been completely sober in weeks, but this is all in the interests of exploring WA!

[DingoZ]

Yeah but we still go and fill the tanks though don't we.

Everyone had a good old complain when petrol got to a dollar for a few months, then the hoorah died off.

Everyone got on the band wagon again, when it was heading to a 1.50. Same thing, died off after a while..

Everyone is now up in arms that it has gotten to 2.00 for 98.

We need petrol though. We can't currently survive without it. No matter what the cost at the pump we will still fill up....

What we should be worried about is the petrol tax, and all these other road charges the government is looking at.... I don't mind paying for petrol, but come on, it's something to shout about if all we are doing is lining the coffers of organisations who ramp up the costs just cause they want a little bit more spending money....

But of course, you must have been down Margaret River way?

[Grub]

Yeah ... {sigh}

I have kept a year's set of records though based on every fill and all the trip details for a year and the results are revealing. It cost me $32.19 more for a year's riding using 98 than it would have using 95. For that $32 I got better perormance and good track day times and if you believe the blurb, I got a cleaner running engine.

early figures suggested the 98 was costing me less than the 95 but then I used 98 for all the track days so that stuffed the conservative use comparison. So I'm happy with taking the 98 option.

Don't get me wrong ill take 98 anytime I can get it.


a lil octane boost goes down a treat on top of 98 :clap:

I read today an article on how its going to be $3/L for probably the standard stuff soon enough. Might have to bend over and take it just like everyone else, thank fuck I can't feel my arse anymore. :whistle:

[Animal]

But of course, you must have been down Margaret River way?

Oh hell yeah! I've been down there a few times now. Strangely, I remember every ride down to the region, but the ride back is always a little fuzzy and vague.
I'm within a ten minute ride to the Swan Valley. Not as good as the Margaret River harvests, but pretty damn good anyway.
Current fave... Devil's Lair Cabernet.
Any bets on how long it takes before this post ends up in PD?

[Grub]

Don't get me wrong ill take 98 anytime I can get it.

Exactly. The point I guess I was trying to make was that I have proven now beyond doubt that it costs no more to run on 98 than 95. Many people have the fear that it's costing them heaps more to run 98.

They can now stop worrying and enjoy the ride :)

[Animal]

Even if I try to ignore the marketing blurb, my bike seems to be a whole lot happier on 98. It responds a little better and I'm probably getting another 40kms or so per tank (open road, hooning) than I get on 95, on the same roads under the same conditions.

Sadly, as long as we choose to ride, we're going to find the money to feed the pumps.

[MaxB]

We are being doubly screwed here. Did you hear a while back the petrol companies think NZ fuel is too cheap? It looks like they have done something about it. In the UK when unleaded 95 hit 1.00 pound/litre our price was $1.49. Yesterday the same web site had UK 95 at 1.11 and our was $1.93. So theirs has gone up by 10% or so and in the same time ours......

Does anyone else smell a big fat rat?

[Nasty]

The problem is that they are currently desensitising us to the fact that gas may go over $3 a litre. Its in the news ... and its everywhere ... exactly what happened with $2 only now we accept it ... the bloody government should be stepping in .. not only on gas (where they take half the ferkin money) ... but on mortgage rates etc which are outta ferking control! :2guns:

[Soul.Trader]

but on mortgage rates etc which are outta ferking control! :2guns:

The government cannot control mortgage rates. That would be completely insane.

[cowboyz]

Agreed. But they could take GST off the TAX we pay as RATES! Paying an extra $126 per year on a tax pisses me off.

Back to the fuel thing. EVERYONE says it is just plain stupid - yet noone seems to be doing anything about it - well what can you do?

My bike drinks 98 like water for some reason. Runs better and smoother on 95with better fuel economy.

[quickbuck]

The government cannot control mortgage rates. That would be completely insane.

No direct control, but in an indirect way they do influence the mortgage rates... What they do effects the rate, so yeah, if they were then to peg it back it would be a contradiction.

[quickbuck]

Heck.... must be a rough ride then....

What ever did happen to that clown who said he could run a bike on water?

Personally I won't be convinced until I see a bike on a track in a race using it.

It'll happen !
Know a guy who's running a 4x4 on water (petrol for start up and excelleration) and getting 900 odd km on a tank full of gas !
Up untill a few years ago anyone who knew how to do the conversions, kept quiet about it for fear of being silenced !
The technology is there, its just a matter of time till its develloped properly !
Mean while i'll just keep paying for 98

[Nasty]

you are right the government controls the rates that run and control the economy .. which controls the MORTGAGE RATES .. putting the circle together makes it sooooo simple.

[henry]

Why do you run 98? It's slower burning so you'll get less power. You should run on the lowest octane that doesn't cause knocking.

[sinfull]

Petrol head from way back and a sharing/caring kind of guy ! Want to share the smell of unburnt feul with those behind me !

[sinfull]

A high tendency to autoignite, or low octane rating, is undesirable in a spark ignition engine but desirable in a diesel engine. The standard for the combustion quality of diesel fuel is the cetane number. A diesel fuel with a high cetane number has a high tendency to autoignite, as is preferred.

It should be noted that octane rating does not relate to the energy content of the fuel (see heating value), nor the speed at which the flame initiated by the spark plug propagates across the cylinder. It is only a measure of the fuel's resistance to autoignition. It is for this reason that one highly branched form, or isomer, of octane (2,2,4-trimethylpentane) has (by definition) an octane rating of 100, whereas n-octane (see octane), which has a linear arrangement of the 8 carbon atoms, has an octane rating of -10, even though the two fuels have exactly the same chemical formula and virtually identical heating values and flame speeds.

[dipshit]

Stop being a bunch of cry babies and look on the bright side. Higher fuel prices is probably going to mean fewer cars on the road and hopefully more motorbikes out there.

Less car drivers will go out for their obligatory Sunday drive and stay home and mow the lawns instead.

Even in the last few years, I have noticed less bogans out cruising around in their old V8's and Holdens. :niceone:

[sinfull]

while engines perform best when using fuel with the octane rating for which they were designed and any increase in performance by using a fuel with a different octane rating is minimal or even imaginary, unless there are carbon hotspots, fuel injector clogging or other conditions that may cause a lean situation that can cause knocking that are more common in high mileage vehicles

Given the fact that mine are low milage bikes and i've not noticed any difference in power tween the octanes, 98 is a pretty yellow !

Mmmm seem to recall something like that, prior to alcoholism setting in ! Now is a lighter shade of heineken !

[fergie]

met a couple from england last week who said that the fuel here is real cheap compared to nz. i do remember how we moaned when it hit $1.00 a litre, but we soon got used to it, i guess we will again.

Waiting for someone to hook onto the bait?

Why do you run 98? It's slower burning so you'll get less power. You should run on the lowest octane that doesn't cause knocking.
Slower burning means it stays burning long enough to burn all of itself, rather than lower octane which leaves some fuel unburnt and goes out the exhaust.

Though I'm keen to see some blind test where people are given some fuel of unknown octane, then another lot and see whether they can spot the difference.

It be interesting to know how markets have changed the price. US dollar versus the Pound and NZ dollars.

Then again I thought the NZ Dollar had become stronger against the US whereas the Pound has stayed relatively the same against the US. This would mean the price of petrol here is even more expensive relatively. Does anyone actually know what's going on?

Well done. That is the stupidest thing I have read on Kiwibiker.

Any sinfull is correct. The octane rating doesn't make any difference to burn speed or the energy in the fuel.

Considering I got told this from a Chemistry Teacher it's actually not as stupid as yourself. Higher Octane means more Octane hydrocarbons than Heptane and lower Octane means more Heptane in the petrol. Octane has one extra CH2 molecule over Heptane so contains more energy. It burns slower but that means the fuel gets a better chance to burn all that is there. Much like how an MSD ignition has a continuous spark so all the fuel/air mix gets ignited. Lower Octane leaves more fuel unburnt. Even the fuel companies claim the higher octane is better for fuel economy and it's not like they wish to be charged for false advertising is it?

And the higher the octane the less chance of knocking. This was proven on my Family's old high mileage car and pretty much any other older vehicle. The slower burning means the force applied to the piston is spread over a longer time, rather than a quicker bang that sends the piston knocking against the cylinder.

[Boob Johnson]

My last bike (RF900R) most certainly reacted differently to 98 & my last car as well (325 BMW Coupe). I got a more willing engine & saved a shade over $5 on a trip from Auckland to New Plymouth (360km's).

Never seen Shell Optimax? Anyone seen that hear in NZ? Not a shell servo kinda guy :oi-grr:

[sinfull]

Nice post DS !
Wondering here if a bike can have its compression ratio increased Via reprogramming rather than taking the heads back and what other stresses would occur in doing so !
Looks like high octane likes high compression ! Worked when i rebuilt a ford v8 to run solely on lpg ! 302 heads on a 351 gave me 11 / 1 compression and it went like a petrol engine !
Edit / Ok thought about it lol like there aint no way to up the compression by other means duh ! the stoke of a piston is the stroke of that piston so without ripping into the guts ya aint gonna change nothin !
if ya bikes manufacturer says 91 ya may as well save a few centsa ltr !~
But if yr in the process of a rebuild its worth looking into for a few more horses i guess !!

[Boob Johnson]

Arrrr so once it's proven you were full of crap you wanna throw your toys out of the cot? :baby:

[AllanB]

When I purchased my Hornet 900 I was told to run it on 91 - owners book also says this is OK - I did a tank on the higher stuff - no difference at all other than to my wallet. 91 is just fine.

[henry]

Arrrr so once it's proven you were full of crap you wanna throw your toys out of the cot? :baby:

I made an incorrect statement, which was corrected by sinful, and I admitted my mistake. Then Coyote backs up my original mistake and throws in some completely arse about face logic which he follows up with a claim that our education system and the petrol companies are the paragons of credibility!

How does any of that warrant your comments?

[Biggles2000]

Great video. It was good to see some actual dyno testing done on the fuels.

I dont think Shell do a high octane fuel, only Mobil in the north island and BP in some stations.

[avgas]

Here is an interesting consideration that only really applies to NZ.
How do they separate Diesel, 91, 96, 98 when they produce these fuel? (rhetorical i found out the answer already).
The reason i bring this up was the fact that my sisters Diesel Camry died some years ago (as did a large number of diesels) and while doing some research we came to the conclusion that it was crap in the diesel (in our case too much sulphur and heavy metals).
Now tell me, if there was to be crap in fuels, which fuel would it end up in?

[ManDownUnder]

I had to laugh - went to the local petrol station... looked at the $$$ meter going up at a scary rate for the guy in his flash V6 4WD thingy drinking the expensive stuff...

$150... $160... etc LOL

It put the $4 bottle of milk in perspective! LMAO!

Petrol's petrol. They'll get what they're given and think themselves lucky if it's not kerosene
