The chemical composition of the LG6 is on page 2 of the MSDS: Mineral oil+ additives. The Mercon SP is the same thing too: "petroleum distilates" page 1 "Base oil: highly refined" Page 11. The price difference could be because Mercon is made here in the US, and not imported. Also, ford drivers, don't have the same disposable income as BMW drivers.
