I know the manual says 9,000 miles on oil changes. How many people on here go that far? It just seems a little far for me. I have always changed my oil around 4 to 5 thousand miles. I am going to be using Mobil 1 4T 10/40. I have a 2015 RT with automatic transmission. It had the original service at 3,000 miles then it was changed at 8600. When I purchased it I did not know it had been serviced at 8,600 so at 10,800 I changed it again with Can Am oil kit. Now I have about 4,000 miles on the oil. That means I could go another 5,000 miles but I don't think I will.
