The manual also says change oil and oil filters more frequently under severe conditions.

The thing that gets me is they also say, However to allow piston rings to properly seat a new or rebuilt engine should be operated for at least 50hrs using standard petroleum based oil before changing to a synthetic.

Now I'd like you to explain to me why I should change from a regular petroleum base oil to a synthetic when a synthetic isn't good enough to use to break my engine in properly. Pardon me that just doesn't make good sense.

I believe the guy in the video, there are no benefits for me to run the synthetic and it's sure not cost effective because I do my oil and oil filter changes every 50 hours.
So the answer is no then.
