Yamalube 2-M and Ringfree

[DC20]

I run Yamalube and Ringfree but was reading the description of the oil:

Extreme Performance Formula:
An exclusive additive blend works to guard against power robbing ring stick and carbon build up, while special additives minimize wear.

So does the oil allready have Ringfree in it?
Am I doing overkill by having both?

no
yamilube is ashless, that is why it is better
spectrum/spectra makes their oil
