I have a husqvarna ts-348xd with the kohler 7000 series. I usually use the kohler brand synthetic oil but my dealer didn’t have any and no idea when they will get it. The parts guy told me a lot of people have been running the Mobil delvac 10w30 synthetic blend or the rotella 10w30 synthetic Blend. Anyone running HD diesel oils in their gas mowers? Is their any issues that could arise from it ?
