Hey Y'all...joining the party late with a 2015. Loving it so...only 700 miles so far. Have been be pumping 91 Octane Shell Nitro Premium (can't find 93 around my area) and will be lubricating with Full Synthetic Oil as she ages. Already concerned about DI engine issues with carbon deposits on the valves and oil waste build up due to the design of these types of engines. If I add a catch can set up I void the warranty as I understand it. What to do? Also any break in advice....haven't been babying it but also haven't been on her like I stole it. I live in WI so she is gonna see some harsh winter weather....any advice on this factor will be welcomed. Thank You....this looks like a very welcoming and supportive forum...thanks in advance to those with the knowledge and expertise for sharing with those of us who are not!
