Is 5% fuel OK to use?
I have no hobby shops close to me and I dont want to spend the shipping costs for the fuel. Recently on an out of town trip I stopped in at a hobby shop desperate to find some fuel and all they had was 5% Wildcat fuel. I am used to using 10%. Is there any disadvantage to using 5%? Is it okay to use it in an engine that is used to 10%? Thanks
