I just put a little over 20 hours on the machine and I'm about to do my first oil change. I'm still learning about all the differences in oils. I know the break in oil is mineral based, but should I be switching to a full synthetic so soon or should I continue running mineral oil?
I've chosen full synthetic Mobil 1 4T 10W40, but I've seen others use regular SAE 10W40... should I be using a specific blend for 4-stroke engines?
