It won't hurt to run the oil with a little Kroil in it- - - - -other than the possibility it might clean the carbon out from under the piston rings and make it use a little oil. On some older engines, a good thick layer of carbon under the rings is all that's holding them tight against the cylinder walls. Clean it out, the rings shrink away from the cylinders, and you've got an oil burner- - - - -or a mosquito fogger!
