I go through a lot of gun and recently ran out so I did what I think most of us would do I went to my local gun shop and what I noticed is gun oil is $1-4 an ounce depending on brand is it just me or does that seem unresonable? which brought me to thinking whats wrong with using motor oil instead at $3 a quart ? Do any of you use anything besides gun oil on your guns veg oil/motor oil ?
