Go back for a pic!!!So, I bought some at Walmart this weekend. The 5 qt jugs were all API SP formula. The 1 qt bottles were SN still. However, the craziest thing was there was a single lone bottle with a really, really, old label on the shelf. I should have taken a pic. I don't even remember that label being the current label 15 years ago honestly. I wonder if it was hiding in the stockroom all these years or someone tried to return an ancient bottle for some reason.
