So I picked up 2 cases of 6 qts each of this oil from BJ's. PQIA tests show this oil specs very close the Amsoil OEM oil. Did an OC tonight on my 14 Focus ST. 6k on the odo. First impressions are engine is quieter. Real test comes later....5 miles from house to work with a DI turbo motor. Used Motorcraft Synthetic blend at the 3k OC. Oil smelled like it came from a lawn mower. Don't need a oil analysis to know there is fuel dilution. How much? don't know, but it doesn't take a science guy to know its there with my short trips and engine type. With filter, this is a $26 OC.
