C&C Sports in Brighton, MI sold me oil for my 600 mile oil change. While I was putting in the 3rd qt I noticed it said "winter blend" on the side. I called the dealer and they said they called BRP and was told it was ok to use in the summer. After many phone calls to the dealer I finally got a hold of the owner of the store. He proceeded to belittle me and tell me that I am not an engineer and I do not know anything about oil. Does anyone else agree that "winter blend" is ok for 90 degree day riding? It is the BRP brand oil. Oh and before you ask, I did buy this and one other Spyder from this dealer this year.
