Correct fuel additive for 2.1 inj petrol

New to t25 ownership, and as above I have a 2.1 petrol, and I note that only 'super' unleaded is recommended, which is fine if you can get it. sadly it's not sold readily in my area, so I'm having to consider a fuel additive/ octane booster. Can you recommend an additive suitable for this engine ?
I used to use Millers VSP in my previous old motors..

Most get away with retarding the ignition timing from 10 degrees BTDC to 5 DBTDC. Of course you are effectively detuning slightly but nothing you would notice.

I would have to agree with Martin ... much easier and less trouble to do that

As the guys say 5 degrees BTDC is definately the way to go

eh?
your Aircooled does not use 97 ron petrol
the 2.1 in question is the high compression 112 bhp DJ
