So what fuel?

[disenfranchised]

Looks like shell came out on top one way or the other.

Shame they might be getting out of the NZ market then

if you have a friend you can trust you can try a little experiment:

Give him a bunch of money and have him allways refuel your bike without telling you what did he put each time. He keeps a log of what he puts every time and you keep yours of what do you believe he put.

I bet you won't be able to find out.

Of course you know that's a joke, as petrols don't mix but form layers due ot the different densities (ie. if you filled with all three petrols they would float in three layers in your tank ... although whether they are all really what they claim to be is another story ...)

Obviously you haven't had a stern talking to the mixture of petrol in your tank.
"Look guys, I know you're all different, but just get along for a while mkay? OR I'LL PUT 91 IN WITH YOU!"

P/t.

^ With newer (EFI) bikes doesn't the ECU compensate if it finds that it's knocking/detonating?

If it has knock sensors. Late model BMW cars are a good example, they retard the timing some to prevent detonation, and you can actually feel the difference in power. Few bikes have knock sensors.

used to run 91 in my girl. then switched to 95 on advice from my old boss. i get more milage from a tank of 95 [lasts about 2-3 weeks, compared to 1.5 to 2 weeks if lucky]

wont use 98 simply cos of the cost.

Don't you have that the wrong way round?
Higher octane means its harder to ignite...hence less likely to self ignite under compression in the cylinder.

You want some of that low grade 88 octane stuff they sell in asia...that'll burn real nice!!

Ummmmmmm ok. I should have done some extensve testing before making that comment

Though in the bigger scheme of things petrol is still ridiculously easy to light.
