I have some oil based kool aid in a vial and I switch between my 25g to a 18g to draw. Is it true that if I use the 25g to draw an oil based kool-aid it will dull the needle beside that it takes forever? The reason I asked I just wanted to remove the step of switching from the 25g to the 18 then back to the 25 to inject a orange hehehe
Thanks
