Adding oil to Cool Power nitro

[B-17]

I've read some old threads on this topic. Im trying to ensure I dont burn up a perfectly good engine.
60 OS been used. Purchased mounted on a plane. Started easy on the 10% by Cool Power.
Should I boost the oil content with more synthetic ? Id prefer to avoid adding caster.
what type, brand of synthetic should I add ?
I appreciate some help on this.

I've run Cool Power in my engines since the 80's with no issue at all. I've never added anything the fuel, I normally run 10%. Great fuel, still run it every weekend.

Thank you Sir for your response. I ran the engine a couple days ago. It runs excellent. Very smooth and even throughout the power band.
I think its time for her to see the sky again.
