There are those that say your rings don't seat properly with synthetic oil, that's why I said cheap oil. Ask rob why no T6 and that will likely be the reason.
Cheap oil and change it often. First 20 miles, 500, 1500, switch to T6 at 3k. Change my T6 at 3500mi. That's what I did. I have 10k on my rebuild and zero oil loss between changes. Could probably stretch the oci, but oil is cheap enough.
