Octane?

Octane?
Hello Friends,
I have an '87 XJ6 engine that was rebuilt with .040 over pistons. A recent compression check showed all cylinders to be between 170 and 175 psi.
I was wondering if I need to switch to a higher octane fuel. It seems to run ok on 10% 87 ethanol, but I'm not sure if that's ok. Any input would be great.
Thank you,
George
