Winter oil change

[Water Warrior 2]

Winter oil for any temps you ride in would not need to be a 10-30 or lighter. The chart in the owner's manual says you can use 10-40 or 10-30 down to 4 below F. I would just pour in a good quality oil with good cold weather flow characteristics and ride on. Synthetics will flow very well at low temps and still provide excellent protection. Both of our bikes have Amsoil 20-50 M/C specific oil right now but did have Amsoil 10-40 prior to the last change. The 20-50 has shear characteristics of a 90 weight gear oil to save wear and tear on the gears. Will also mention this as an alternative...........one of the Vstrom riders has been using Amsoil 0-40 Power Sports oil for quite some time with no ill effects noted. He does long distance trips as often as possible and does work the bike within reason.
