Zoli76, you really know how to lift the mood! 
Dude, I hope that was just a really strong joke! WD40 e-liquid is the kind of thing that would really be a âcoil killerâ, but not in a good way! 
I think that 18mg/ml 50/50 WD40 combo would definitely loosen every screw on your tank, but your lungs probably wouldnât thank you for it! Letâs stick to proven flavors, and leave the liquids in the toolbox for the tools! 
Let me know if you have any more serious (and less toxic) questions! Vape safely!
