ktm recommend you use a 10w30 oil for the 2 stroke and you will need 0.75 litres make sure you get all the old oil out though otherwise you will overfill it and that can be as bad as under filling it ..
32:1 ratio
Supreme (or the highest grade) gas and (automotive) synthetic 5w 30 oil if you can't get to a bike shop. It's best to use ktm oil though. And if you're referring to two stroke oil, you can use basically any two stroke oil concentrate but again is best to use ktm oil
Engine oil, KTM recommends Motorex ATF Super (Dexron II Gear Oil) Premix, KTM recommends Motorex 2T.
