Bests & Worsts Reviews from Amazon

Hey, it's synthetic oil with all the proper ratings to use in modern automobiles. But it's also refined by the same company that makes Wally World Syntec full synthetic motor oil and WW sells it for about $16 for 5 quarts so that will continue to be my go-to supply. Amazon is facing the cost of shipment factor in a lot of bulk items now and it's making them less competitive on price than they were previously (but more profitable which makes stockholders happy). Assuming it is the same as Wal-Mart, I've sent samples of their synthetic off to Blackstone labs for oil analysis on various occasions and it always tests very, very well (as well as the Mobil 1 samples I've sent off) so I'm not embarrassed about buying the house brand for my cars. If Amazon gets competitive on price, I'll gladly purchase it from them.
