I like 'old school' but I would probably recommend 0-20 motor oil and a quart of marvel mystery oil instead of a quart of oil. Just a thought. Years ago(yeah , I'm THAT old) we didn't have '0' weight oil available for stuff like this....And be patient , don't go over 2K RPMs it for maybe 1/2 hour then drain & fill with OEM rec oil & GOOD filter. And follow whatever else goodguy suggests cause , my profile ....never mind. Good luck.

drain the oil and run it with tranny fluid it will clean some of gunk out then drain the tranny fluid and replace with new oil
