I forgot to fill the Ute up last week so I pulled into the local garage and they didn't have anything except 91 so I filled the Ute up with that, now I never noticed any difference in power loss and I got better mileage out of it too.

I drove to my girlfriend place and then we went to Nelson and back and I set the odometer when I filled up and I got 703km to the tank, it averaged 10.5L to 100k's. On 95 or 98 I average about 11.5 to 12L on the same trip.

Most people have said if you use 91 it uses more petrol, I wont be using 91 all the time but it was an interesting thing to do when you need petrol and there's nothing else but 91.

i used to run the ba on 91
95 made no differecne to the performance but 98 was noticeable

91 fuel in this country is crap ....... i won't even run my lawnmower on it!

So the SP only runs on 95/98 - its really because you need all the power you can get

Dont we all Zam ... dont we all!

The amount of head gasket failures that i get that can be directly traced back to detonation or preignition due to lack of octane is quite staggering .....

I must admit that when I put 98 in the Ute I did notice it was a lot quicker all round.
