I can't seem to find the Castrol 2w 40 that matched Vic specs. Is it OK to blend 10w 40 and 20w 50 of the same oil: Castrol Act EVO 4T?
I run 20w-50 in mine with no problems. I have been using the Castrol V-Twin 20w-50 but have now switched over to the Redline 20w-50 motorcycle oil. There is no need to blend, the Freedom 106 and transmission will run fine on the 20w-50 oil.
