DIESEL FUEL + 2T OIL = Superb performance?

[big_fletch]

I recently bought a litre of Castrol 2T Self Mix (for lawnmowers, lawn edgers and stationary engines). Haven't put it in yet. Is this the right stuff or should I have bought Castrol Active 2T like Fletch used?

I used the Active 2T because it apparently mixes the best with diesel, not sure about the one you bought though.. I imagine it would be ok as long as its a mineral oil.. Cant be 100% though
