You risk making your blend too oil lean regardless of where you reside. Not a good idea, IMHO.I live in scotland
well what i`m asking is, if you allready have petrol in the tank with the correct ratio of mixing with oil, but if say you need more fuel and you don`t have oil, could you put unleaded petrol in the tank and mix it with the existing oil and gas, or would that just mess up the engine?
I think that sound you hear is Pablo weeping....Me and my buddy were at a friends house on our motorbikes one day and all his fuel leaked out because of a broken fuel line. We rode to the gas station and he filled up. Neither of us had any 2 stroke oil on us so he rode on home with straight fuel in his tank. That was ~6 miles to his house where he added some 2 stroke oil, he did put a little extra in that tank but he hasn't had any problems from it at all.
That's something that is NOT recommended to do, but can be done if needed. Just be careful and not ride WOT when you do it.
