You know how there's always a little premix left in your ratio rite; no matter how long you hold it upside down when pouring. Well, for this reason I have two ratio rites; one for the gearbox and one for premix. I got them mixed up yesterday when changing my gearbox oil and used the premix cup, which had a dash of premix in the bottom. I hate to dump that new fluid just because of a little premix. Do you think this is an issue? Should I dump the new fluid and refill just to make sure? :confused:
