I have used Marvel Oil for years to unstick stuck motors where rings have sat and begun to fuse to cylinder walls, and it has ALWAYS done the job. I use it regularly in my flathead antique motorcycles (added to gas) and it appears to give the valve guides a little more protection in these types of motors. Used to experience galled fuel petcocks (brass to brass) in my '48 Indian Chief, but a few ounces of Marvel in the tank made that problem disappear, too. All in all, I like the stuff.
