Oil for two-stroke engine

Does anyone have experience with four-stroke oil in two strokes? One told me that he had taken a muscovy trainer and stirred it to Trabos, and drove the engine 57,000 km. And he never bought 2MT. And how they scared us that she made ash and abrasive carbon :-)

1 Answer

Answer :

I wouldn't try it until today's two-strokes ...: o But it's a fact that the Trabants and Wartas rode a lot (and it stinked accordingly), after all - even a friend refueled in his S11 and refueled it with an indulo. ..: o I don't have my own experience - I took care of S11.
