any 100 % synthedic oil will work fine also. KC troble free oil works fine, so does Cobra snake oil. DONT use DOW of anykind on the vik. not even on the reg. Just put two drops of oil in the macro fitting on the reg, and shoot w\o paint 20 times. Then move the ram forward and put 2 drops of oil behind the ram. then manually cycle the gun 10 or 15 times. your done.
