Finally, there is a simple tool that so many two‑stroke fans have been waiting for. Easier to use than a weather app! Just enter how much gasoline you refueled and the mixing ratio you need → the app instantly calculates the required amount of oil for you. 2 seconds and you know exactly what to add! SimsönMische must not be confused with and is not affiliated with the popular mopeds from the former GDR. Warning: An incorrect fuel mixture can damage or destroy your engine!
