Hi! The next summer I will participate to a very long raid of 100hrs more or less with other airplanes much more slower than mine. To stay in pair with them I have estimated a power setting that consumes 12Lt/h, this should  be 35% more or less. 
There will be any problem maintaining this settings for a whole 100hrs? 
And there will be any problem using AVGAS maybe with Decalin? An oil change is programmed at 50hr. 
Thanks

    The 915is operates with a Lean Mixture, so fouling should not be an issue.
    The issue might be, Can you fly Slow enough to keep up (Back?) with the pack.
    Also consider that below your VY speed, MORE power is needed the SLOWER you go.

    Good to hear this Bill. Yes I will be more or less 1,3 - 1,4 times my Vy. 
    Thank you.

    So, what is it that you are flying that you consider 1.4 x Vy to be notably SLOW! 
    That sounds more like a casual cruise speed.
    I am picturing you trying to formation fly the 915 Turbo next to a Powered Parachute.
