I have a few big trips coming up and generally on these trips I have to mix fuels due to availability. Is anyone aware of any potential problems mixing 98, 95 and Avgas. I have a 914 Rotax and haven"t had any problems on previous trips but just wondering if there is something I should be careful of as I will be flying through some pretty desolate country.All fuel that I put in my gyro goes through a Mr Funnel.
