oil based lubes will detonate between 1k and 2k psi typically. dont ever put it in ur tank! u will die upon filling it, no joke. Put oil in the asa (vertical asa that is, remove the reg, put a few drops in there.
iv noticed u can put it in the on/off asa, but the threas there can get dirty so u just pust dirty oil into the gun, put it in the vertical asa imo. leave it at factory fast eblade settings (E1) idk what is good for E2, but factory is the best typically. have fun with it! I love my karnis!
