A couple of us at David's open house / garage party were discussing engine oil and I couldn't remember exactly what I just changed to.
Schaeffer's Supreme 7000 Synthtic Plus 10w-30
It's what my engine builder recommended and it's manufactured in St. Louis.
Amazon sells it, you can buy it online from Schaeffer's, and at a number of local retailers (NAPA sells it, not sure if they carry that specific type/weight, I'm going to check). Or you can search on their website: Schaeffer Retail Locator
