Thinking 9300 miles between oil change is a bit to long I changed it at 6000 miles (9000 on the Spyder) and sent a sample to Blackstone Labs to be tested. Received the report yesterday. Everything came back positive and with a recommendation to wait until 8000 for the next change.
Looks like BRP got this one correct

I changed over to Mobil 1 10-40 and will wait the 9300 miles and have it tested again
