Yes but look at the percent of the oil blend. I have been running Power Master for decades in my four strokes, YS and OS with a Saito or two tossed into the mix. 15% nitro and 18% blended oil. I never go below the 18% oil and I have noticed the new Power Master has a lower oil content. When all I could get was Wild Cat 15% it only had 16% blended oil. I tossed in two ounces of Klotz oil blend to make it up. I also use nothing but blended oil, I don't care for straight synthetics but other people swear by it.
