Suppose i do use a quart of MMO...think it might cause engine leaks?
Neons have issues with the rear main seal walking out of the bore. I have seen several, the seal will work loose and be riding up against the flex plate/flywheel. It is not an oil or additive related issue. I don't know if that was the case with your car, but that seal is a known issue.
