Repotting an olive tree- which compost please.

I am repotting my olive tree and have been told to use John Innes no. 3 and grit. I will probably add about ten per cent grit. I was also advised to mix in multi-purpose compost 50/50 as that person thought I would not have much John Innes no.3. As it happens I have loads so would it be better to use it alone or mixed with multi-purpose? I also bought 'john Innes no. 3' for mature plants by accident, hope this will not make too much of a difference.

Thanks.
