Oil for GBB and Tornado grenade?
I am still very new to airsoft and learning as I go asking questions relating to springs and so on...
My question is regarding oil used on GBB and Tornado grenades.
I have one of each as I purchased the piece that fits on top of a propane tank to refill my (pistol) mags and my tornado grenade which also came with oil. However, the GBB label says do not use for Tornado grenade and Grenade oil says not to use for GBB.
Do you buy two propane tanks, one for the mags and one for the grenades or I am overthinking the whole idea?
