Iím fixin to get the scoot ready for the season, I went to the local auto parts store to get a new oil filter, and oil. I have a 2009 Suzuki Boulavard C50 with 28,000:miles on it and have been useing Valvoline 4 stroke motorcycle oil, 10-40. They were out of that so I got Castrol semi synthetic 10-40 4 stroke motorcycle oil. Is that oil OK to use in my scoot ?
Thanks Skrapiron, I just wasnít sure if I could use a semi synthetic after useing regular motorcycle oil.
Iíve always used what I hope is good oil, the oil Iíve been useing until now was Valvoline 4 stroke motorcycle oil. I change the oil and filter every 1000-1100 miles, some of my buddies laugh at that and tell me to save the changed oil for them to use, but thatís OK I figure the inside of my engine should be in Pretty good shape. Again thanks youíve been much more than helpful to me since Iíve joined this forum, and I greatly appriciate all the help and answers youíve given me.
The "okay to change from natural to synthetic?" and reverse has been subjected to plenty of sure-enough scientific research -- google and you can find lots of it. But as Skrap has said, the final conclusion of all of it is that which type you use and whether you change from one to the other really does not matter. The things that do matter are -- be sure you are using motorcycle and not automobile oil, and change it often.
