After some thought, I would like to choose another oil analysis company (instead of Blackstone, who I have been using). The reasons being because they are slow to complete the analysis and they do not provide accurate information for fuel dilution (and no information for soot content), two parameters I am very interested in monitoring for my 2019 Hyundai Tucson with a 2.4 L Theta II. So, if anyone is interested in making a recommendation, I am certainly listening. Thanks!
