Which oil?

[motorguy222]

Of these two oils only,which would be better.Wal-Marts Supertech,which seems to be going through some changes,or Advance Auto brand oil which at last contact was made by Coastal? Coastal is now Warren-Unilube.Which of these 2 only would be better?

Since we have a lot of data on Wally's oil (uoa's and voa's), and nothing much on Coastal, I would go with Wally's.

Coastal also had some qc problems with their 5-30 and cold cranking issues.

My vote would go to Supertech.
