You bet, they are capable, would I do it , no, but then i don't buy a new sled every year either. That law stipulates that no manufacturer can require you to use their oil. that doesn't mean their oil is better. they just can't require you to use it. I don't think someone has the "best" oil. I just think synthetics are better than petroleum based oils. So I use synthetic in my truck and sled, and boat. Not that it really matters but my last truck, which I sold to a personal friend, is now on 200,000 miles with no, no, internal component failures. I used synthetic oil in that truck from 10,000 miles until I sold it at 85,000 miles. Oh, yea, it's a Ford. Doh!Originally posted by vipersj
This imply's that all machines (engines) must be capable of running any brand of oil meeting the standard set out in your manual.
