I need to find some fuel for my little campstove (an MSR Internationale with refillable cannisters), and can't seem to find the right stuff. I'm hoping for White Gas (Coleman fuel), or even Essence C, but can't seem to find either of those anywhere. I've tried the local sports stores here in Paris (Aux Vieux Campeur, Decathlon and GoSport and even Auchan and Carrefour) to no avail. Any ideas either in Paris or out? I can use car fuel in this stove, but would prefer something cleaner.

Thanks
