Rotax 912 mogas/avgas

[Adam]

Hi all,

I know that the use of avgas reduces the time before service from 100hrs to 50hrs. Can anyone tell me what the ratio of mogas to avgas is if using mogas as the primary fuel, but filling up with avgas on trips out, before I have to consider reducing to the 50hrs for a service?

Cheers
Adam

Just to answer my own question, the service bulletin recommends that if you introduce Avgas more than 30% (30 in 100hrs) of your flying time in the 100hr period, then the service period is reduced to 50hrs. 
Well done me.
