$50 Craigslist 360 EXTREME budget rebuild??

I have a quart of pen grade I could pump through it first? What's with the big call for zinc here?

get some zinc in that oil before running it. Even if you go to the auto parts store and grab some Rislone for 8 bucks, get something in there... this stuff will work from Advance auto parts store. Like 8 bucks a jug
