AEROSHELL OIL SPORT PLUS 4
This type oil has been specifically designed for ROTAX 912/914 series or for other 4T engines: temp, altitude, constant RPM, etc.
Its specs are very convincing. They also claim it to be suitable for gearboxes.
It seems that other oils are more designed for the motorcycle world.
I would like to known if anyone has experience with this oil.
