Hi Carpe,
I have the same rig but is early days yet as I only have about 15 hours up so far. The first service will happen next week.The dealer told me to use only premium unleaded and so far absolutely no issues starting the engine. It runs smooth, no smoke, no fumes , but I do notice that it when you go to start the motor it does not crank all that fast and I am assuming that is normal for this motor.
I will look at the replies to your thread with interest..
