I will be purchasing a slightly used 2005 yamaha rx-1 snowmobile that has 103 miles on it. It has a 1000cc 4 stroke 4 cylinder engine, same as the r1 sportbike. Many owners of this same sled complain of very high oil consumption, and some speculate that babying the engine during the break in period is to blame. I have read that yamaha recommends 15 minutes of idling to break in the engine. My question is would it be a good idea to use dino oil for a while before switching to synthetic? I would prefer synthetic because of the operating conditions the engine will be facing (many cold winter starts), but also want the engine broken in properly. Does anyone think that synthetic oil would prevent the break in from occuring?
