Hi guys,
Nearly turned over 13K miles so far on my 2018 LTD S/C. This past oil change I sent off a sample to Blackstone and the report is attached. I'm not going to review the S/C because nothing has changed since my last post:
Magnuson Supercharger 2K Mile Review and 6K Mile Review
No issues. MPG is settled on 16.9 with 80% city driving which is still better than my wife's 14 LTD basically stock except for Nitto Terra Grappler 17" tires.
I've only used AMSOIL Sig series 0W-20 since I brought it home. Typically put on about 5k-6k miles between oil changes. Yes... likely could go longer but I actually enjoy working on the car and with the RCI skid the oil change is quite easy and fast.
