Motor oil will lubricate your gun but I wouldn’t think there be any (and/or sufficient amounts) of solvents to clean out the carbon buildup. Plus, how clean is it burning when you fire? There has to be a lot of smoke.
CLP is specifically designed to clean, lubricator, and protect the weapon, hence the acronym. It’s definitely more expensive but, like the lube your mom uses, a little goes a long way.![]()
