2010 2.0T base model
So I’ve seen across some threads that a lot of people use either 5w30 or 5w40 grade oil in their turbo genesis. I for myself currently run royal purple high mileage 5w30 in my BK1 and change the oil bout every 3000miles just to keep it clean, but I’ve seen some talk around here about the use of 5w40 is better for the turbos. My car currently has 125k miles on it and it’s kinda hard to find a high mileage 5w40 oil. For context I live in Southern Cali. So we don’t get much extreme temperatures here, and I for myself don’t drive to crazy I’m a pretty conservative driver as my bk1 is my daily .Do y’all recommend using oils catered to high mileage cars? And what do y’all use? 5w30 or 40? Should I make the switch to 5w40 even if it isn’t a “high mileage” oil?
