I've just started using this flare kit on mini split systems and setting up sling sets, by far the best I've had. The instructions say yes, oil, but not the type. I would recommend using the same oil as the freon you are working with so there is much less chance of contamination. Otherwise, the easy housekeeping works perfectly.
