Go ahead bro used engine is good for u.
There are so many civilize way to protect your gun and this is the worst.
Used engine oil contain so much wasted chemicals and had a lot of metal from engine block those elements could damage your gun. There is a reason why car needs to keep changing its oil, on the other hand u put rubbish on your gun sounds smart.
There is a notice on the engine oil bottle says u shouldn't contact the engine oil directly with your skin despite it may sound over exaggerate but why should i do that.
