All here is my latest UOA, I have switched to Amsoil 15w40 but am concerned over high iron...I ran this oil 1300 miles longer than I wanted but due to last minute trip I could not replace filter and re-top oil level. I planned on running another 8k miles but will re-sample in 4k miles (btw I added 1 1/2 quarts with new filter). Not to doubt Blackstone but I did take a second sample and send to Oil Analizers, this should be available tomorrow afternoon...
