Premium petrol prices?

[The Stranger:Me]

Ditto - sick of prepay. My local Shell doesn't bother so they get as much of my business as possible.

I could bear filling up at the Mobil next to work when they had EFTPOS at the pump but since the wankers turned it off I haven't filled a car or bike at a Mobil. Don't plan to any time soon either.

+1 on the mobil pre pay.
I wonder if mobil realise how many people avoid them thanks to their company policy.

I try and use the Pack and Slave petrol forecourt purely so i don't have to remove my helmet, I don't get to worried about the price when it is something i do for enjoyment.

Filled with Force 10 at Gull this morning. Paid 1.49.9c/l.....

Discuss.

This isn't school, you know.
You can't just go, "Blah blah blah. Discuss."

The answer is: profitability (or price gouging, depending).
The keep the price on 91 lowish, but claw back a few shekels on the other fuels.

Because BP Ultimate is 98 octane and have always been 14 cents more than 91 octane. 95 octane tends to be 5 cent more than 91. I think Mobil synergy 8000 (98) Is 11 cents more than 91 octane. I use BP Ultimate because my bike runs sluggish on other fuel and it only cost $2 more everytime I fill up.

I think the Gull price you put is not right I think it is $1.50+ when I saw it in the weekend and that has that 10% ethanol blend in it.

Yep ditto to all that...however I think it is a tad pricier at Tairua...

Personally I don't give rats what the price at the pump is between the different octanes. The bike gets the HIGHEST octane possible no matter what...

The car? well sorry Subby but you're on the cheap stuff LOL.

Simple, don't buy 98. It's a rip anyway.

If your bike will run 91, you get more power from it anyway.

Anti-knock systems on modern bikes will retard the timing so will give you worse economy if you're running too low octane so it's pretty easy to check.
Of course if you don't have knock sensors you should probably play it safe.

Most modern bikes don't have knock sensors, and don't have particularly good airflow sensors either, but that's another story. "Snow White and the Seven Swarfs", I think.) I think it's because they rev too high, so the knock sensor would struggle.

i noticed my bike was bit gutless and also drank more when i ran bp 98 ulimte at a bp which only solt 98 and not 95/96 rip of bastards.

Check your manual. I can.

From memory my manual says it will run ok but may void warranty over 5% (Gull has 10%). I called Bluewing and the confirmed that is the case. They did say Honda will probably change their mind once all fuel has an ethanol component.

As for the prepay...I just wave my arm (or go in and ask if they're busy) and they unlock the pump for me...
And I don't think it's cause they recognise me...cause I seem to always see different staff

Some Mobil's seem to be ok. Others aren't. I can't be bothered working out which

Yep, funny how people assume more octane is more power.

Interesting. I guess my bike is special

Umm... you did read my signature lines, right?
I generally either make stuff up, or extrapolate (wildly) from the few facts I do have. I have no idea how many injected bikes have or don't have knock sensors.
I know that despite have 23,762 sensors, my EFI bike doesn't have a knock sensor or airflow sensor, but maybe that's because it's a V4, and that fucks things up.
I'll extrapolate from that....hmmm... it's a V4, so a knock sensor would get confused and take the normal V4 'character' as knocking.

Ack Shirley, it was knocking sometimes when hot, until I disabled the oxygen sensors and dialled in some more fuel at low revs.

But it's on the internets so it must be true

Only if you quote and annotate it appropriately:.
