Welcome to the forum and congrats on your '15. I bought new and owned a '15 CR-V EXL for 3 years. It was our 1st CR-V and loved it, never a problem. Hope you have the same good luck too. I changed the oil and oil filte around every 5,000 -6,000 miles regardless of the Maintenance Minder and always used 5W20 Mobil 1 Synthetic. You should probably change out the CVT fluid using the correct Honda fluids. Your owners manual is your guide.
