I'm about to try LubriGold full synthetic 5W-20, blended by Warren Unilube in Dunn, NC. A retailer there has it in cases of 6 for $3.53 a quart, everyday price. Yes, it's from a small, independent blender/bottler, but it has to be an awesome buy at that everyday price. I know AAP has the Havoline synthetic special running now, but I like giving business to the independents. Any opinions or ideas out there?
