If other companies don't follow, will Shell raise price?

You might have to ask Shell that question!

Shell usually are the first of the big 4 oil companies to drop prices and the last to put them up.

Unlikely, I would think.  If it wasn't economically viable, the price wouldn't have dropped - and if it was a promotion it would have been advertised.  If the others don't drop their prices they'll lose trade and as rscole86 has pointed out BP (at least in Johnsonville) have now also dropped their prices.

I gues the oil companies had a change of heart since the aricle in theis mornings Dompost saying that the AA didn't  know what they were talking about and their suggestion to drop the price by 4 cents was based on inacurate information on the current market..

Shell however made a big song and dance and branded their fuel v power, which is the name given to high octane fuel in other markets, while here its still only 95 octane, IMO trading unfairly on the brand getting recognition in other markets as being a viable alternative to BP ultimate.

So since they dont sell good fuel, I still go to BP or mobil for the skyline.

Yep, it never fails to amuse me that the second the crude prices go up overseas, the pump prices shoot up here.
But when the crude prices drop the fuel companies spin us the line abouthaving to wait for the price reduction to filter through.
What total bollocks.
Also the fact that all stations for a company are told to adjust the prices at a given time with no regard to the actual cost of the fuel in their storage tanks. 
So you can pretty much take whatever line they spin us with a pinch of salt.

And yeah, V-Power.  Whatever. 
I too have to go to BP or Mobil only as the raace car doesn't play nice on anything less than 98.

Even the lantis gets better power on 98, and thats a na nana-wagon, but it doesnt see the change in milage that other cars do so its not quite worth it putting 98 in it for around town driving.

Any difference in power on a Lantis between 95 and 98 is placebo effect. Garuntee it.
Octane doesn't increase the energy in fuel, it only increases its resistance to pre-ignition, or detonation. Thats why higher octane fuel is used in highly strung out engines, because with normal fuel, the compression is so high, that it would cause detonation.

If a standard car has more power when using 98, that means its probably been self retarding ignition to prevent detonation.
98 can have benefits over 95 with no power gains however, such as preventing knocking under load. However if you usually find yourself in this situation, you change gear down. Or your auto box does it for you.

Typically, the cars that perform better with 98 than 95, and get better milage, are imported versions from Japan. They have a much higher octane rating at the pump than we do in NZ, such as 101 and 103. 96 is their lowest.

I've tried various fuels over the years in different cars and have found BP 98 to be the most economical fuel. I get approx 10% more distance out of using 98 over 91 fuel, so actually works out cheaper. There is also a noticeable torque increase at lower revs; I think this is the key to the fuel saving as apposed to it making the engine more powerful.

It will hold 3rd up hills that it has to change down when running the cheaper stuff, and it has marginally more pull away from the lights on 98 Difference is there when doing the how fast can I get up to on the motorway onramp test - no way near the difference between 91 and 95, but still you can definatly hear the difference, less labouring sounding when below 2000 revs, I think thats why there is no savings is that unlike most cars, its sitting about 3000 revs at cruising speeds on the motorway.

Its quite amazing that the autobox and the engine management can work so well together to make it operate pretty well on almost anything you throw into it. Other then the massive shake and almost stall when the crappier fuel first goes thru they hardly miss a beat.

 I dont know what the compression is on it but its certainly not very high or turboed

Interestingly Shell V is 99 Octane in the UK - and BP Ultimate is available in 102 octane!

I know, thats why its just shell in NZ cashing in on the name and giving nothing different. If they tried charging more for it I know several people that would be annoyed since they have shell cards.

Some servos in the states will have 5 grades of gas in them, why is it that NZ ones seem to think that just having 2 is enough. I cant go to gull anymore since they dropped 95 for the biofuel stuff which isnt compatible with my car. Why the hell not have 3 options instead of 2?

My Audi is supposed to have 95 as a minimum - it likes 98 better.

I had a Saab 93 Viggen that I used to run on 100 in the UK - wooohooo!

richms: You should be able to use Gull's Force 10.
Part of the problem is that because it contains ethanol, it corrodes the rubber in older fuel lines, however Gull have said that they've put anti-corrosive additives in the fuel to prevent this. If they were lying, they'd be in big trouble when the fuel lines leak and cause engine fires....

Its actually 95 rated octane fuel, but the blend of ethanol ups it to a 98 octane equivelent because of ethanol's cooling properties. Its another way of lowering levels of detonation.

It is meant to use more fuel, as there is less energy in ethanol. Strangely enough though, I switched to it in my MR2, and by the second tank, I got 500kms out of it as opposed to the 400kms I usually get.
