Fuel Octane Question

[chrisandliso]

Hi Everyone
I have just purchased my first ski. It's a 2012 GTI 130.
I believe the ski was sold brand new somewhere in America and has been imported into Australia to resell.

Just a question regarding which fuel to use. The owners handbook says "87 RON inside North America, 92 RON outside North America".... what should I run the ski on here in Australia? Standard ULP which is 91RON or the higher 95RON premium. Can I do any damage running on either? Apologies if it's a dumb question but don't wanna screw up a perfectly good PWC by doing the wrong thing.

Thanks guys
Chris

I found this.

I contacted Shell Australia to determine our (Australian) equivalent octane compared to yours (USA). I received some results that may assist with mapping.

As you most likely know Australia use the RON octane rating and you use AKI.

The conversion is: (RON + MON) / 2 = AKI

In Australia we have two high-end premium grades of fuel available:
98 RON
100 RON (includes 5% ethanol)

So, using Shell’s information, I have calculated the following ratings:

Shell V-Power 98: (98 RON + 85 MON) / 2 = 91.5 AKI
Shell V-Power Race 100: (100 RON + 89 MON) / 2 = 94.5 AKI

Note: Shell V-Power 98 is far more available than the V-Power Race 100 octane grade.
