If you were responding to my statement about the 5-50 synthetic, I think you missed my point. It appears he tested a much thicker "mineral oil" solution than most USA cars run these days, so the test isn't really valid to USA cars. The mineral oil may solidify at a much higher temperature than modern synthetics.They make zero weight synthetic.
