Use whatever you wish it's just my opinion to buy and oil and pay more to add stuff to it when you could just buy a top grade oil that you can ensure all additives are blended to work together.
Just doing some light digging there is some speculation that there is chlorinated parrafins in motorkote (from independent lab test on bobistheoilguy) which can cause corrosion.

If you believe in it and think it works then great go ahead but I'll just rather stick to something developed with all additives working together and have multiple long term test data to back up claims.
