You guys are awesome. Back in 2017 I had analysis done on our Hyundai sonata and you noted excessive iron in it. Now after the major recall and issues from Hyundai on metal not being cleaned out properly from the factory it all makes sense after a larger chunk of the lose metal finally lodged in our motor this past weekend and caused it to seize. Sure hind sight is 20/20 but the dealer ships are reading codes on their scanner trying to listen to noise to identify affected engines (which ours past even after the oil test…). In REALITY the dealers/Hyundai should be sending oil samples for analysis to you to identify affected vehicles! What a mess 🙁
