I know these oil threads have been debated several times and Im sure my question has been covered numerous times, but All I simply want to know is this: I normally run the Honda HP-4 synthetic oil in my bike. Since I am due for an oil change before I officially put it up for storage, I was wondering if it would be ok to put the Honda GN-4 non synthetic oil in over winter time. Since its reccommended to change oil before you store the bike and again before you start riding in the spring again due to condensation collecting and deteroration of the viscosity of the oil over extended time periods; I would change out the non synthetic oil and put the synthetic oil back in, in the spring. My only reasoning for going from synthetic to non synthetic, back to synthetic is to save some coin. I am not interested in replys that tell me how to winterize a bike or what oil to use, etc... all I want to know is will be ok to use the non synthetic oil during winter only and then switch back to my normal synthetic in the spring. I want to avoid this becoming a big "what oil to use debate." Thanks in advance.
