Rotax 914-avgas or Mogas

[KarkelB@aol.com]

Hi folks,
             just been reading the march issue of todays pilot magazine. 
There is an article about fuels that just confused me. Read through a 
paragraph that says mogas is unsuitable for turbocharged engines. Previously 
i had read that avgas damages the valve seats on rotax engines. Now whats the 
truth? I think i'll be calling austria tommorrow. Anyone with  long term 
experince on either fuels with the rotax engine?

     regards Karim.
