If you're interested in an oil analysis, you cannot go wrong with Blackstone. Great company.
Had this done for the race car after every road race weekend event., valuable.I'm a huge fan of Blackstone Labs. Used to send a sample in after every oil change for my 2017 F350 Super Duty Powerstroke. I never took that long, though (4-6 weeks). I was getting them back in a couple of weeks, tops.
