Hi guys, just popped in to book the car in for a service. I asked what oil they put in and they said SOLARIS 5w-30.. I'm fairly certain that's not what's in the car right now, I think there is 5w-40 Triple R Carlube... Isn't 40 better? Should I just do the service to keep FSH and swap the oil for the nanodrive 5w-40 I've got waiting for the car?
