I use .2 but a lot of people say .45 will do. You could probably get away with not adding any ba but if it makes you feel better just add a tiny bit especially if it is only 20 ml of oil or else you will be in a world of pain when you inject it if you add too much. you can use 10cc syringes but make sure the oil is good and warm to hot in order to push the oil threw the filter. I did it once by hand and my hands were sore for days. The caulking gun method is the best but you will need a larger barreled syringe to use that method.
